Jock vs. Nerd

part two

Had this little thought in my head...in a quirkless!college!AU...where you're a pretty girl, a popular one too...also, you're a very dominant young lady...and where you fell for the friendless, geeky, shy nerd...Izuku Midoriya...and leaving the jock, the most popular...the hottest guy in school...Katsuki Bakugo...heartbroken.

Thoughts on this? I have.

Warnings: ANGST, Bakugo: one sided-love, Deku: What? A hottie wants to date me?!, You: Come here, cute nerd! <3, Bakugo is a himbo, you're smart and pretty, Izuku's shyyyyyyy

Just to be clear: English is not my first language, so please bear with me :)

[your name will be Yena here. :)]

Have fun reading:

---

"I'm telling you, she likes you!", Denki nudges his jock friend Bakugo, who only swats the blonde's hand away from his shoulder. The Bakusquad was known for being good on the field in football and so being pretty popular already, but scoring even more points with the chicks because of their good looks, and with Mina Ashido being the cheer captain, one of the most popular girls in U.A. High and also one of your best friends.

And you.

Oh, please.

Don't get him started.

Should he start on how he met you? How he fell for you when you yelled back at him which made him flinch? How he couldn't get that cute frown and sweet pouty lips -which he never could stop daydreaming about kissing- of yours out of his head? How he thought that you were a literal angel when you treated his wounds? How softly you spoke to him, not yelling at him for losing their big game because of him?

Or how you'd always help him and the team out in their finals because wow; A hot and intelligent human being taking their time explaining them the subjects with a sweet voice and soft smile? Where Denki milks out every single advice and reassurance he can get form you, blushing like crazy with a stupid and smug grin directed to his teammates (where these signal him that they would kill him as soon as the study session with you was over) when you pat his head comfortingly?

Where Sero openly subtly flirts with you and you think he's only joking and flirt back, only to have him gulping while looking to the side with a shy grin but bright red face? Where Kirishima looks at you like you hung the stars because you explained him the difference between Mitosis ans meiosis in baby steps until he got it, and he gives you a dopey, lovesick grin with heart eyes. And he'd gasp softly when you'd call him a "good boy!" for explaining the difference after you've explained it to him ten times patiently (Everyone glared at the himbo with murderous intent).

Or where Shinso and Monoma asked you out multiple times in a row with you having to check your calender -a sweet, old fashioned-themed little book with a real feather and ink to write on- turning the pages a concerning amount of times with your delicate fingers (which makes the guys wish it'd be wrapped around something of theirs instead of that little book of yours) giving them a sad pout before telling the whole football team that you're not available until the next four months, which leaves the two least shy guys groaning in despair out loud and the rest looking to the side with a frown and some even cursing under their breath.

Sure, he was jealous that his teammates were ogling at you and blushing when you praised them since they were all crushin' on you, leaving him fuming in his seat, but oh, look how the table fucking turns and lands back on its legs like nothing happened when he finally has your attention. And even when he tries to listen- he really does! -he can't help but admire you.

You, who is so fucking hot and smart Bakugo's actually surprised that he hasn't popped a boner yet.

You, his childhood friend of nearly ten years, starting from pre school and onward, who he never thougth he had a chance with you until he got your attention in these little lessons you gave them, where your focus seemed to be on him and him only, where he started to sweat like crazy, especially his hands and his heart beating rapidly, his pen already slipping out of his hand, and when it does, you catch it with a fond smile before giving it back to him. However, you lay one of your soft hands on one of his caloused and scarred ones and you sigh and he thinks that you're going to ask him out on a date, to marry him, to confess your feelings to him in public-... when all you say is: "I know all this stress is taking a big toll on you, Katsuki. How about we study for fifteen minutes and do a little break, hm?"

And he can't help but nod, because suddenly, He feels a big stone in his throat, he feels like crying, scratching his eyeballs, hitting his head against a wall, because why would such a perfect little girl want to go out with a dumb himbo like him?

He knew that he was more the annoying best friend to you, because he always bullied you for being smaller than him, but no shit because he was literally a six foot something giant. He couldn't even attract you with his handsomeness, nor his rippling muscles and flexing body when it was too hot out in the summer and when he subtly tried to steal a glance at you, wanting to know if you were checking him out like all your girl friends did around you, he only found you giggling at something on your phone.

Yeah, Bakugo put on his shirt after that with a hurting heart, leaving your surrounding friends whining like greedy little bitches and running towards him.

...

Bakugo sighed. It was a nice dream Denki told him. Because Bakugo knew how much of a big, fat crush you've had on Deku. But what made him become your crush?

Deku's always invested in his books.

Deku's never seen without his baggy pants and oversized hoodies.

Deku's never talked to a girl except Uraraka or his mom.

Deku's never had a friend (except Bakugo himself) over at his house.

Deku's always muttering and scribbling away in his notebook or phone, where he's playing a nerdy fantasy game in the medieval times and sometimes whispers a silent, cringey: "Thou shalt be killed with that goblin-sized brain of yours...!", before you can hear a faint growling and slicing sound coming from his phone.

Deku, who never seems to actually take care of his hair, which is always in all places, too curly, or always in his face where he combs his fingers through his hair to actually see what he's doing.

And then you come into the game.

Whenever Deku does any of his little- to you very cute -antics of his, you sigh dreamily while looking at him while he writes away the english assignment he had trouble working on and you were more than ready to help him, leaving Bakugo gagging and growling quietly, staring daggers into your and Deku's head.

Or when he was over at your place, and he tried talking to you but you were too engrossed in something your phone showed you, he got fed up and snatched your phone quickly, Deku's name flashing as the chatting contact and then, he is being shoved down the ground from little ol' you, who is on top of him. Big, buff and strong Bakugo being overpowered by little sweet you, his big nose flaring up after he caught a wiff of your sweet scent and bakugo can already feel his dick twitching from where your heat was resting, but you quickly took your phone back and went into your room. However, you didn't close the door after you told him to get the fuck out of your apartment with an embarrassed red face. bakugo groaned and stared up at the ceiling, heart and dick throbbing in pain.

That's when he knew that you were crushing on his childhood friend.

...

One day, as you were chatting away happily with your friends, you spotted Izuku and called him over. The thing was, it would've been okay if you were with two or three of your friends, and if you guys were chilling in front of the classroom, or on campus. But no.

It was in the fucking cafeteria where you, Yena Hideyo, called a guy over to you. A cafeteria, where you were surrounded by your dozens of friends, all eating and munching, also surrounded by even more people and the cafeteria was extremely full today. Still, you beckoned him closer and suddenly, he felt all eyes on him.

I mean, it was the first time that the most popular girl in U.A. called a guy from the same age over to sit next to her and have lunch with her, except the freshmen, where the girls and boys all blushed from your milf motherly care and were asked about how school was and how you, their senior, would do everything in your might to help them. (U.A. ended up being the highest scoring school in Japan, thanks to a little help of yours) Also, they'd all blush from the close proximity you and them were in, because they could smell your scent, your glowing, sexy figure, where your thick thighs threatened to spill from your mini skirt, or how you had a too small shirt with a much too big cleavage on, where your large tits were spilling out a bit, or how your sweet tummy rolls were so cute -visible from the stomach-free top you wore sometimes- that they had to restrain themselves from pinchining them, or how nice your hair always looked, and with perfect makeup.

That's how Izuku felt, like a freshman, when he finally sat down next to you after he took an eternity with everybody's glare on him.(it actually took him less than ten seconds to speedwalk from his previous spot to yours but who cares) he could feel your unintentionally strong gaze on him and he allowed himself to feel important for once. I-if you were looking at him like that, then it was hard not to think that he wasn't special in at least some way. Izuku could smell your sweet vanilla perfume, but didn't dare to look into your beautiful face, let alone away from his hands in his lap, because if he even caught sight of your nice thighs, he'd be a goner, choke on his spit or thin air and die. He could even hear the thoughts his peers where having. How come Yena calls over such a loser? How come he gets her attention? What's so special about him? He's a nerd!

But you don't seem to care in the slightest, just happy that your favourite nerd (and crush) has taken your plea to sit down next to you. "How are you Mido? English hard? Do you need tutoring lessons?", you started speaking already after he took a bite to let him think about his answer, your friends looking at this little interaction with offended and confused faces. Why was he eating while you were speaking to him? Can't he chew a little faster to finally answer you?

And after he was done finishing his first bite, he began to ramble, but only for you and the person sitting next to him to cromprehend. "W-well, I actually do have a little trouble with English, but I think I'll manage, I don't want you to take more than you can handle- I mean, y-you- of course, you can handle things! You're- you're Yena Hideyo after all! I just d-didn't want to bother you with my problems, since you're already preparing the decorations and routine for prom and the big game is starting to come closer too and I just don't-"

"Breathe, Izuku.", you said gently, holding one of his hands which he was fumbling around when he tried to explain himself. You led it towards the table and smiled at him. Of course, he'd blush like crazy and nod before breathing. Unfortunately, the person sitting next to him was no other than Katsuki Bakugo, who'd of course laugh at him for not being able to speak coherently let alone look you in the eyes. Also, Bakugo wanted to embarrass Izuku in front of you as much as possible, so that you'd finally stop pining after that nerd and start catching feelings for him. That resulted in Izuku pale-ing/paling(?) and eating his sandwich until it was no more, all the while he had to endure this bullying side of Bakugo, which somehow still, never dissapeared.

"Ahahahahha- haaaa...you're one funny guy, nerd. Always muttering shit and not even being able to talk to Yena-" "Kats, that's enough. Drop. It.", your stern voice echoed in the big cantine, leaving everybody in shock.

They knew that you were Katsuki Bakugo's best friend and rumours spread around like crazy whenever students saw you and Bakugo interact with each other, playing with the thought of you and the jock being a couple and all. What they didn't know, for example, was that you, their little sweet sunshine of U.A., who'd always aid with a soft smile and calm voice, could hold such malice in her voice and glare at her friend of ten years with such hatred.

It left the eating ones stop chewing, the talking ones stop gossiping, the loud ones become quiet and Bakugo look at you with a shocked-I'd even dare say betrayed expression on his face. Even Izuku looked up from his sandwich to look to his right, where Kacchan was looking at you, then to you, who was giving him an annoyed look. The school bell signalled that the lunch had ended, much to everyone's dismay, and they all walked out with food in their hands.

You packed your things, but not before whispering something in Izuku's ear before you went away with your people, all the while not sparing the blonde football player a sliver of your attention. Izuku quickly stood up and ran as fast as he could, because 1. He talked to his crush-resulting in his heart beating rapidly against his chest, and 2. His crush stood up to Bakugo, with the whole school seeing them bicker wich was rather embarrassing to Bakugo...yeah, he'd kill him for that. And since Izuku didn't feel the need to die at the moment, especially after you've seductively whispered in his ear to meet you at 6 pm sharp, he ran up to the library to hide in the labyrinth of bookshelves, because Bakugo wasn't really known for his knowledge in this area, but he could still catch up to Deku.

However, since Deku knew this world of books like the back of his scarred hand, he easily dissappeared between the endless seeming shelves with his scrawny, thin body, leaving Katsuki lost and irritated. After a while, after Izuku was long gone, Bakugo found the exit and puked into a nearby dustbin because he couldn't stand the chance of seeing so many books, even though their backs were facing him. It scared him that there was an endless variety of pictureless books, where it wasn't like in comics and he also never understood actors and actresses in movies who always said that a movie would play while they were reading a book. so much for being a himbo.

...

"There you are!", you exclaimed happily, also glad that Izuku didn't leave you waiting any second longer. He even rang the bell to your apartment one minute earlier, which was probably because his watch was set one minute earlier so that he wouldn't come late to meetings and school and bla bla bla-

"U-uhm, yeah! You look pretty!", he said loudly, and you giggled. Taking his hand, you lead him to the living room, where all sorts of english books and literature were piled on top of each other. In total, there were only ten books, but they were thick.

Izuku was left dumbfounded. He thought that maybe, just maybe, you...well...uh, well!

"Are you hungry? I made us some pizza.", you said after he sat down and looked at the pile of books. He only nodded, a little dissapointed at the fact that he didn't get dicked down by you(...yet).

As he smiled up at you with a nod after he put on his sweet round glasses -with you internally dying of his cuteness- you made your way over to the oven of your apartment because you were already a big girl and could look after your own money which led you to invest in stocks and become rich but that's for another story (?👀?).

As you were taking out the pizza to examine the quality of the crust and middle part, being satisfied at how nice the cheese had melted, Izuku came inside and noticed you in an apron. To him, you were looking like his sweet little housewife, ready to be taken care of at the counter where he'd first eat you out and then the pizza-

Aaaaaaaaannnnd there went his dignity with his cock straining against his jogging pants. Well, shit.

"Hey Mido, need somethin'?", your sweet voice asked him and he felt his heart squeeze because you were just so perfect to him and he couldn't believe that he was alone in your home with you. "I-I jist, uh, I mean, I j-just wanted a glass of water-", and he pointed towards the sink behind you, "C-can I?"

This left you gasping and you smacked your head. "Silly me! Where are my host-manners!? I have other beverages as well! Orange juice? cherry juice? All Might smoothie? Apple-" "A-ALL MIGHT!", The nerd interrupted you and you couldn't help but burst out in laughter in his cute little antics and fanboying towards his idol the ingeneering master, Yagi Toshinori-Also known as all might.

"Okay sweetie!", you cheered before going to the fridge and giving him a fresh All Might smoothie. (it was literally a protein shake.) He loved that you didn't tease him for loving what he did, and he felt very precious in your presence. you never ushered him to something he never or didn't want to do.

Izuku took the smoothie with a precious grin and thanked you before going over to the english books and reading through them. So that's how you were always on top of the classroom...you must have been studying like crazy. And these books were amazing! He instantly understood what he did wrong when reading through the explanations.

The smell of perfectly baked pizza caught his attention and you put the sliced food in the middle of the table. You looked at him holding one of your books. "Understanding?" "Yeah, Thanks."

You smiled. "That's good to hear."

You were on your laptop, looking through some of your investments and writing emails like a professional and Izuku blushed. What were you not actually? You were smart, helpful, nice, sweet, calm, a good advisor for young and old, and you were pretty. And here you were too, helping him out by lending him some of your books to read and learn, and not expecting anything in return.

Even though he was thankful, he was greedy. Especially when somebody as extraordinary as you offered him an endless amount of help. He wanted more of your attention, more of your sweet words, and...your touch. Your hands and lips on him. The ony thing was, were you feeling the same? Probably not.

I mean, look at him, he's a nerd! Nerds don't get pretty girls like you. He could already imagine your phone going off any moment with Kacchan calling you, to ask if you'd be free today and then you'd excitedly say-

It seemed like he was staring at you too long, because after a while, you looked at him before stopping to write in your laptop. "All okay?"

Midoriya gulped nervously. Well, here goes nothing...!

"I...Uh-well, Uhm. There-there was s-something I'd like to tell you. B-but promise that you, well, that you won't laugh- or look at me with a disgusted face, or well, not a good reaction! I-just, I...I like you. Like, really, I really, really like you. I always have! From the moment I saw you for the first time where you helped a freshman reach their class and I couldn't take my eyes off of you, because you were just so pretty- which you are still now!-, and because suddenly, many people were talking to you and you had answers for every question they had.

Or the time where you were helping a teacher with finding their exams and when they found it, they were sooooo happy. Or just...all those other times, where you were just ....there!..... for everybody.

And it made me think...what about you? I want to help you. I like you, and I want you to get something in return for all those nice things you do everyday for everyone. So...what would you like to do?"

You looked at him for a moment of pure shock, not expecting him to know about your little dilemma, or even confess to you. Sure, you loved helping people, but you didn't like owing them stuff, or them having to do something for you. So...hearing your crush confessing his feelings for you and wanting to help you too, that made you swoon.

You hugged his arm and sighed. "...can we stay like that?"

Izuku gulped, feeling your soft chest, and small arms hug his toned arm, your knees on his thigh. "S-sure...!" But he still didn't get a reaction from you for his feelings. "Uh, would you like to go out sometime?"

You hugged him tighter. "Let's do that another time, love. I just wanna be close to you right now." And that made the boy happy.

"I'm surprised that you could see through my act though.", you said after a while, tracing some of his veins and scars which made the boy errupt in soft shivers. "D-don't wanna be creepy...but I can always see you...and I only see you helping people. Never anybody helping you."

You kissed his cheek by his little speech and he made happy noises. However, you didn't stop. you started connecting your lips to the arm you were hugging and pulled up his sleeve further and further until Izuku had to take it off. He was in a short sleeved grey shirt, oversized, and his thin arms were shaking with anticipation. Each time you kissed one of his freckles or scars, he felt more and more nervous. Sure, it felt nice and he cherished the moment, because it was very intimate to him. But still, he had his worries. He knew that you'd become a romantic maniac with your partner, but he never thought that he might become yours. Or were you just messing with him? Teasing him like the girls in middleschool did?

"Uhm, Yena-" "Hm? Wanna stop?", you asked, immediately backing away and about to let got of his hands when he grabbed them tightly. Strong shaking of the head. Your hands played with his hands and he felt his anxiety and bad thoughts drift away. "Wanna do something else?" Another shaking no of the head. "'want you to k-...kiss me...more...please?", he pleaded, looking up shyly to you with his thick long eyelashes. God, his eyes were so fucking pretty...!

This time, you let go of one of his nice but shaking hands and gently grabbed his cheek. "...Like...this?", you whispered against his mouth with hooded eyes and he whimpered, already leaning in with closing eyes. And when you brought your lips against his, he felt amazing. Every cell was partying as he grinned stupidly against your lips and intertwined your fingers with his, his other hand holding your hand which was on his cheek. your thumb caressed his cheekbone and Izuku sighed into the kiss in pure bliss. How many nights had the nerd been dreaming about kissing his popular crush? How many times did he want to hold your hand and just have you close to him? He couldn't remember and didn't want to either, when he had the real you right next to him, and taking his first kiss.

After a while, you parted and looked him into the eyes before smiling giddily and burying your head in his scrawny chest to giggle like a highschool girl. He was happy. If you were giggling like that and still holding his hand- this time more tightly- then it had to be that you were in love with him as he was with you. he hugged your frame, but something caught his eye; Bakugo.

The jock was standing in the corridor, his backpack threatening to fall down and scare you when it crashes to the ground, face twisted into anger, jealousy, hatred and hurt, and heavy, quick breathing. If Bakugo had been here a little earlier, he might've changed something, but no. He saw everything. From the moment where you started to kiss his knuckles up his shoulder and then...kissing his lips. Like you two were a real couple. You really loved Izuku.

he went out again and called one of the girls Denki recommended him. "Yer free t'night? Need to fuck out some pain."

Blake and rose for the shipping game?

the first time i've ever won a bingo game on here AND i won it Twice. rose and blake quite possibly the near ideal ship to win this board. the thing is that my prior Poasts about the inherent love-hate feelings rose theoretically has about blake as The Man She Could've Been are not actually canonically accurate--blake isn't rose but w/ different lived experiences. but also. during the time period wherein i did not know this, rose also did not know this. so the post still holds true up until blake dies badly. and even Afterwards them being two splintered halves of the same person (meiosis vs mitosis) is just as good or better. and sure you could kill the other person 2 take Everything but this would mean u r an incomplete person. forever. you see what theres grounds for here. i presume this is how they end up with rose climbing inside blake or whatever it is shes doing in that one out of context pact clip i vaguely remember. which is basically the next best thing to weird sex since blake cant actually masturbate in front of the mirror anymore due to his dickless cock with no balls.

Mitosis vs meiosis

[dementedspeedster]

“Okay, yes, but no… like, twins come from a different source, not directly from the other, so I don’t think I get it…… is this like a mitosis vs meiosis thing, cause that concept never made much sense to me…”

"Ok, ok, but regardless of the source and how I was made the majority of my DNA matches his. We are nearly identical in appearance save for hair color. Just, look he's not my father. Never will be. Can we agree on that?"

"Mitosis vs. Meiosis: Key Differences, Chart and Venn Diagram | Technology Networks" https://www.technologynetworks.com/cell-science/articles/mitosis-vs-meiosis-312017

Everyday the entire human race becomes dumber and dumber because we are listening to people who think they are smart even though they are so out of touch with our natural world.

Religious beliefs are the absolute worse people to tell us about earth and who we are as people because it defies nature. The next is the idea of different races for humans, to believe in this you are the world's biggest idiot.

You can't be a separate species if you can reproduce reproductive offsprings and this is elementary biology. This is why I am posting mitosis and meiosis to explain to the dumbest people on our planet.

Somehow they didn't teach you elementary biology in school or you were just too dense to understand this basic concept of reproductive life. Plants and animals all go through this exact same process of providing representative life.

Everything fucks and this is a fact, without sex everything goes into extinction. Please my dear earthlings let's become smarter than we have been in our past history, we should know better by now.

Class 9 Chapter 5: The Fundamental Unit Of Life-Biology

Fundamental Unit of Life

Cell Theory:

Proposed by Schleiden, Schwann, and Virchow.

States that all living organisms are composed of cells, cells are the basic units of structure and function, and all cells come from pre-existing cells.

Types of Cells: -Prokaryotic Cells:

Lack of a true nucleus and membrane-bound organelles.

Examples: Bacteria and Archaea.

Eukaryotic Cells:

Have a true nucleus and membrane-bound organelles.

Examples: Plant cells, animal cells, fungi cells.

Structure of Eukaryotic Cells: -Cell Membrane:

Semi-permeable outer boundary of the cell.

Regulates the entry and exit of substances.

Nucleus:

Control center of the cell.

Contains genetic material (DNA).

Cytoplasm:

Gel-like substance that fills the cell.

Houses various organelles.

Endoplasmic Reticulum (ER):

Network of membranes.

Rough ER has ribosomes; smooth ER is involved in lipid synthesis.

-Ribosomes:

Site of protein synthesis.

Golgi Apparatus:

Modifies, packages, and transports materials within the cell.

-Mitochondria:

Powerhouse of the cell.

Generates energy (ATP) through cellular respiration.

Vacuoles:

Storage sacs for nutrients, water, or waste.

Lysosomes:

Contain digestive enzymes.

Break down waste materials.

Plant Cell vs. Animal Cell:

Plant Cell:

Cell wall and chloroplasts present.

Large central vacuole.

Generally rectangular in shape.

Animal Cell:

No cell wall or chloroplasts.

Small, multiple vacuoles if present.

Generally round or irregular in shape.

Microorganisms:

Bacteria:

Prokaryotic cells.

Varied shapes (rod-shaped, spherical).

Some are beneficial (e.g., nitrogen-fixing bacteria), while others can cause diseases.

Protists:

Eukaryotic, unicellular or multicellular.

Examples include amoeba and paramecium.

Cell Division:

Mitosis:

Cell division for growth, repair, and asexual reproduction.

Results in two identical daughter cells.

-Meiosis:

Cell division for sexual reproduction.

Results in four genetically diverse daughter cells (gametes).

Importance of Cells:

Cells are the building blocks of life.

Cells carry out all the functions necessary for an organism to survive and reproduce.

Cell as a Living Organism:

Cells exhibit characteristics of living organisms, such as metabolism, growth, response to stimuli, and reproduction.

These notes provide a brief overview of the fundamental unit of life as covered in Class 9 Science.

Diploid vs Haploid - Difference and Comparison | Diffen

Diploid cells reproduce by mitosis making daughter cells that are exact replicas. Haploid cells are a result of the process of meiosis, a type of cell division in which diploid cells divide to give rise to haploid germ cells. A haploid cell will merge with another haploid cell at fertilization.

[adj444]

MAR. 21 '23

BUSINESS: started just a little of insurance revision but didn't get too far or anywhere in general..no we still do not have our mocks corrected or returned <3

AG. SCIENCE: 5wks till project due oooo okay well ignoring that we did farm layout planning which technically counts as an experiment but well yknow

economy of labor = making things ez for yourselfff put related things close to eachother ie summer dairy parlor & grazing platform, winter dairy parlor & winter housing, wide access for milk lorry 2 avoid reversing into yard, calf sheds near paddocks incase weather gets cold... store silage & feed close together like silage pit & concentrate storage... separate machinery vs. animal access routes

health & safety = separate fenced play area in line of sight of house; waterproof outdoor electrical sockets; fence water off; clear visibility = no crowding of shit; sliding doors cuz swinging doors are dangerous in high winds; signs; designated parking area for machinery

sustainability: hedgerows, field margins of wildflowers, fence off waterlogged grassland to turn into wet grassland meadow habitat...use 1 single tank to collect all soiled water... 16-22wk slurry storage... buffer zones = areas maintained in permanent vegetation adjacent to rivers and streams that help maintain water quality, prevent fertilizer & chemical runoff

BIOLOGY: everyone give a big round of applause for more plant sex

MALE GAMETE FORMATION:

4 pollen sacks in the anther, 1 diploid microspore mother cell in pollen sacks

diploid microspore mother cell divides via meiosis to form a tetrad (cluster of 4 haploid cells)

tetrad breaks into 4 individual haploid cells (microspores);

haploid cell divides by mitosis to create diploid pollen grain

pollen grain matures and forms an exine (rough thick outer layer) and intine (thin inner layer) around it, 1 nucleus = tube nucleus & 1 nucleus = generative nucleus

gen nucleus divides by mitosis later on into two sperm cells

FEMALE GAMETE FORMATION: polar nuclei + egg cell + embryo sac = female gamete

diploid megaspore mother cell divides by meiosis into 4 haploid cells; 3 of these die

remaining haploid cell divides by mitosis 3 times to create 8 haploid nuclei within an embryo sac; 5 of these die

2 remaining nuclei become polar nuclei, 1 remaining nucleus becomes egg cell

FERTILIZATION:

mature pollen grain lands on stigma

mature pollen grain absorbs water

tube nucleus controls the growth of a pollen tube through the stigma, down the style and thru the ovary to the micropyle (chemotropism!), degenerates upon meeting micropyle

generative nucleus moves through pollen tube

generative nucleus divides by mitosis into two sperm cells

sperm cells move past micropyle into embryo sac

1 sperm cell fuses with 2 polar nuclei = triploid endosperm (food source for seed), 1 sperm cell fuses with egg cell = diploid zygote

i have a sci formative 2day btw. on dna structure and function and meiosis. i’m studying hard rn. so quick notes that i know:

dna carries genetic information from generation to generation.

it is located in the nucleus of cells.

dna is formed like a ladder or a “double helix” shape, it is anti-parallel.

dna is made of long strands of nucleotides bonded together.

a nucleotide is made of a sugar and phosphate backbone attached to the nitrogenous bases.

it include the pairs: adenine and thymine, cytosine and guanine. a can only bond with t, and c can only bond with g. theyre <the bases> bonded by hydrogen bonds.

oh also 2n means 2 diploids, 2 sets of 23 chromosomes while 1n means 4 haploids, one set of 23 chromosomes.

DNA is a polymer of nucleotides

A protein is a polymer of ___

now mitosis vs meiosis:

mitosis has only one division

created all body (somatic) cells eg. blood cells

produces two diploid daughter cells

has genetically identical daughter cells

creates a human cell with 46 chromosomes (2n)

occurs in somatic cells + all organisms except viruses

meiosis has two divisions

creates gamete cells

produces four haploid daughter cells

has genetically unique daughter cells

creates a human cell with 23 chromosomes (1n)

occurs only in plants, animals, and fungi

similarities:

starts with a diploid parent cell

produces new cells

cells undergo dna replication

meiosis phases

interphase: G1, S (DNA replication), G2 (longest)

prophase 1: connects and forms a tetrad, crossing over of DNA (this creates genetically unique combination) forms chromatids:

metaphase 1: tetrads line up in the metaphase plate

anaphase 1: pairs of homologous chromosomes separate + sister chromatids still attached

telophase 1: nuclei and cytoplasm divides, now a haploid set of chromosomes in each daughter cell.

cytokinesis 1: cytoplasm divides.

prophase 2: spindles form, there is no crossing over of DNA, nuclei disappears

metaphase 2: chromosomes line up at metaphase, because of crossing over in meiosis 1, the chromatids are still genetically unique

anaphase 2: sister chromatids separate and move towards opposite poles.

telophase 2: forms four haploid daughter cells, nuclei reappear, each daughter cell is genetically unique.

cytokinesis 2: cytoplasm divides.

eukaryotic cells dna

pycaryootes

vocab:

cytokinesis -

chromatids -

nuclei -

tetrad -

spindles -

Stage Three, Randomized Review associated with Twin Man Skin Development Element Receptor Only two (HER2) Restriction Using Apilimod Plus Trastuzumab in conjunction with an Aromatase Inhibitor throughout Postmenopausal Ladies Using HER2-Positive, Bodily hormone Receptor-Positive Stage 4 cervical cancer: Updated Connection between Substitute

One particular important element involving apomixis will be apomeiosis, a new deregulation regarding meiosis which results in a mitotic-like section. All of us separated and recognized the sunday paper gene that's directly involved in controlling #Link# entry to the 2nd meiotic department. Through combining a mutation on this gene using 2 other folks that affect important meiotic functions, we created a genotype known as MiMe by which meiosis is totally replaced by mitosis. The particular obtained crops create useful diploid gametes that are genetically just like their own new mother. The roll-out of the MiMe genotype and apomeiosis phenotype is a step toward comprehension as well as design apomixis.\\ Inspiration: The loud character involving transcriptomic data stops the particular organic significance of typical network centrality actions, often utilized to pick gene applicants throughout co-expression networks. Consequently, new resources and techniques have to improve the forecast of mechanistically critical transcriptional objectives. Results: We propose an original circle centrality measure, called annotation transcriptional centrality (ATC) computed simply by including gene phrase information via microarray experiments with natural knowledge obtained from community genomic listings. ATC computation formula delimits consultant functional websites in the co-expression network and then relies on these details to discover important nodes that will modulate reproduction of useful affects within the community. All of us show ATC power to foresee essential genetics in a number of experimental designs and provide improved upon biological importance over conventional topological community centrality steps.Function: To gauge variability associated with worked out tomographic (CT) proportions involving lesions of assorted sizes and also perimeter sharpness in many areas obtained #Link# through readers with different numbers of expertise, while would be within program scientific apply. Materials and techniques: Within this institutional assessment board-approved, HIPAA-compliant retrospective review, Seventeen radiologists using various numbers of experience separately acquired bidimensional orthogonal axial sizes of 50 lymph nodes, 120 lung skin lesions, along with A hundred and twenty #Link# hepatic skin lesions, grouped by measurement and border sharpness. Do it again measurements have been carried out 2 or more several weeks later on. Intraclass link coefficients as well as Bland-Altman plots of land were utilised to evaluate intra-and interobserver variability. Results: Pertaining to long-and short-axis sizes, respectively, overall intraobserver contract costs had been 3.957 (95% self-assurance interval [CI]: Zero.947, Zero.966) and also 0.945 (95% CI: Zero.933, 3.955); interobserver contract costs had been Zero.954 (95% CI: 3.943, 3.963) and also 0.941 (95% CI: Zero.929, 0.951). Both intra-and interobserver deal differed through sore measurement, border sharpness, location, and also viewer encounter. Deal ranged through 0.847 for you to 0.886 for skin lesions Twenty millimeter as well as more substantial vs . 3.745-0.785 with regard to lesions on the skin smaller than 12 mm, 2.961 for you to Zero.975 with regard to clean margins as opposed to 3.924-0.942 pertaining to unpredictable edges, 2.955 to be able to Zero.Ninety seven with regard to respiratory wounds compared to 2.

Lily: Who said you were smart?

James and Sirius: We'd say that we're smart.

Lily: Ok, so what's the difference between mitosis and meiosis?

James: Don't fall for it Sirius, she's just making up words.

floofty and triffany collaborating on Cursed Info Posts like the kirby meiosis vs mitosis one when one of them is having a bad mental health day and want Cursed Content to help. they are very memorable! floofty's students have mixed feelings about the ones that get used in their lectures. extremely helpful! but so, so cursed.

They are good friends! But far too cursed at times.

Mitosis vs Meiosis

*

Hello Everyone!

I am coming into the last teaching weeks of the semester and I am pretty excited to finish my first semester in this new degree. I am mainly excited for next semester as I have two courses that I am really looking forward to taking, an introductory infectious disease course and an introductory genetics course. I am thinking that over the holidays I could start to post some notes for my Spanish learning as I won’t have any university content to post.

Happy Studying!
