Gonna ace my quiz tomorrow!!

[@1220MrCool]

Taking the AP Biology Exam tomorrow. Definitely getting a 1 or a 2 on this :/. I just cannot understand how people understand all of this. Is it memorization? How does it come easily to people? I have struggled with this course all year. :( I am normally the Math freak and loved Calculus.

[@nicolaskaros4997]

+Mr. Cool In the same boat here man, good luck

[@1220MrCool]

+nicolas karos Good to luck to you too man!

[@yujinj2903]

AP Bio to me is all about memorization of key facts and applying it many different ways and to many concepts.

Why is there a slight variation between the percentage of A and T or G and C?

Good!!

[@michelebeneducci8007]

The Hershey Chase experiment used radioactive isotopes, not dyes as stated in the video.

[@cassommer6749]

Martha Chase experienced dementia. She did not "go crazy". What's sad is that Hershey didn't acknowledge her involvement for years and she was unappreciated throughout her life and career.

[@YG2025]

I guess it depends where you go to school. I didn't have a Honors Bio class in my middle school which I'm guessing you did or at least you took it prior to entering high school. I didn't have that opportunity.

[@werq34ac]

AP Bio is usually offered to Sophomores and above, not freshmen. Bio honors/regular is a prereq for AP bio and other AP sciences at our school.

[@octavioboris2190]

IF IT LOOKS EASY....I DOUBT YOUR EXPLANATION!

[@YG2025]

I never bragged about being in an Honors Bio class so how am I thinking highly of myself? I actually sometimes feel that I don't deserve to be in advanced classes so contrary to your belief I am not a narcissistic & vain honors student, just a girl. Anyways, I was just a bit puzzled by the fact that the other person had that material on a college bio test & like someone pointed out before, the material expressed in the video is not really college bio material (unless used for review purposes).

[@jDudinec]

YO WHAT UP CONROYS CLASSSSSS!

[@lesbeanpandas]

"And you can't get a Nobel Prize if you're dead." Lol. You're videos really help with AP Bio! :D

Thankyouu!

[@DoubleT1995]

Do you support genetically engineered foods? are they safe?

[@cathleenharrington444]

For the Hershey Chase experiment I thought they labeled the phosphorus an sulfur with radioactive "tags" not dye

[@MYEHLICHIZDAEPIX]

they did not use dye. they just used radioactivity. it was illustrated with dye because radioactivity cannot be seen in pictures.

[@billybishop1997]

I'm studying about this in high school right now.

[@useurcamera]

@Dudodit yup. that's so sad..

[@sherayabentick6156]

"and you can't get a nobel prize if you die.." haha idk why that made me laugh (x

[@MsToy11]

I'm watching this video for our semi-final exam tomorrow...

[@Sweetiegirl18]

lol. I think the person meant "college biology" in high school, as in a college course and honors course. no way in college would students need to review such simple material. They should have these basics down. And I wouldnt call it "unfair"; I'm majoring in Biology by choice.

[@ToXiicSNiiplEz]

Im in 7th grade Science, this is so easy. Well not like THUPER EASY, just enough so that i know what he's talking about. Your videos are really easy to understand and i love watching them for fun! Thanks :)

[@xstardestroyer1379]

Do you still watch them for fun even tho you like 23 now? 😂

[@bobjones9693]

I've noticed people are always talking about the huge yet forgotten role Franklin had in the discovery of the structure of DNA,but everyone's forgetting about Chargaff.He didn't get a Nobel prize either and his discovery was as important as Franklin's

[@Aya-ho2cw]

mmm so it's just a coincidence that Franklin was the only woman involved and the only one not to get the Nobel Prize? highly unlikely..

[@starclanman]

+Ayako G It's less because she's a woman and more because they stole her work and didn't give her credit. The scientific community didn't learn she was involved until after her death, and the award isn't given posthumously.

[@HomebrandMusic01]

+Ayako G Yep. She died.

[@charity4613]

martha chase wasn't included in the nobel prize that alfred hershey won for the experiment that they did TOGETHER. it's sad how many women weren't honored for their scientific contributions

[@misorihara]

Aside from that it's ridiculous in the first place how Nobel Prizes aren't given posthumously... Rosalind Franklin was not recognized for her contribution to discovering the double helix probably until a long time after her death due to the sexism in the scientific circle back in the days. Any acknowledgement to her was fairly muted and almost always coupled with Wilkins' name. It's quite sad actually.

[@dongdestroyer6077]

franklin did all the work

[@plutopuff]

He didnt ask if it was helpful!!! :o

[@alialast6271]

+the-screem-queen check part 2 of the podcast c:

[@YG2025]

I don't brag, why does everyone assume that all the people who take advanced classes brag? Unfortunately, many people know I'm in advanced classes but only b/c word just kind of gets around & I've been in advanced since I was young. Anyways, I hate when people know b/c they sometimes take advantage of me & teachers from my normal classes automatically expect more from me. There's more pressure put on you from peers & educators so it's not always fun, contrary to some people's beliefs.

[@jasonlionbar1911]

Hi my friend " I had A dream A couple off weeks back were I so my Cells being laserd bi mini lacers ... And just before I woke up ' I heard DNA to RNA" watt does this mean I've had A Lot off lucid dreams off late 'butt this one had words and I heard RNA " thanks ".❤️❤️❤️⚔"

[@YG2025]

Yea looking back I don't consider it unfair. I was never much of a fan of biology and I was stressed over my final so I guess wasn't in the best state of mind to be posting that comment. Anyways, best of luck with your major in biology! Personally, I find it biology interesting yet it's not really my favorite subject.

[@iiserkfreedomfighters1913]

[@roffigrandiosaofficial]

[@maxkadan]

Hello

[@YG2025]

I never said that. I was saying that why were both of us learning that same material at such different points in our academic career. Secondly, I'm not brainwashed. I know my generation isn't the best but honestly if you're so grown up, why are you stereotyping/generalizing?

SHOUTOUT IF YOU'RE FROM MS. HENDERSON'S CLASS BREH.

[@WeatherStationZ41]

He's not disparaging the college kid, he's just wondering why they didn't get the opportunity to learn it sooner. That's the only way the "unfairness" he mentions makes sense. No need to be derisive.

[@Patt5]

Martha Chase didn't "go crazy", she suffered from dementia. And "mental illness" or "mental health problems" would be a much nicer way to call it anyway.
