Entire 2024 AP Biology FRQ Exam – Full Explanations by AP Biology Teacher

Hey All, here are explanations to ALL 6 FRQs on the 2024 AP Biology Exam released by college board that took place on May 16th, 2024. I truly hope this is helpful to whoever is watching! Remember, these are “proposed answers” as of now as the scoring guidelines have not been released yet (will be released usually in July when scores come out). If your answers do not match, it doesn't mean they are wrong, many times on AP scoring guidelines, they can accept multiple answers. If I am wrong on an answer (which I may be - sorry), please comment below to help us all out! Thanks for watching and I hope this video is helpful to you.

Here is a link to the 6 FRQ questions released by College board I will be covering in this video:

i watched literally all your past videos in prep covering the frq in prep for this 2024 exam, and i love how enthusiastic and reassuring you are!! they have helped tremendously, you seem like a kind soul and a great educator. your energy is contagious and thanks for these!! i’m a little nervous for how i did lol. but seriously, these videos are awesome and i recommend them to my friends!! keep it up :)

Hey! This was a great video.
For 1aii, I think that your answer is what I originally thought, but I think here the idea is that if the sister chromatids crossed over they would have either 0 or 2 fluorescent markers. Since some haploid gametes will only have one, it means that crossing over didn’t occur.
I think the right answer would be that, “Some of the haploid cells formed after meiosis will have only one fluorescent marker because the sister chromatids on each homologous chromosome that eventually separate into haploid cells were not involved in crossing over.” or at least something along the lines of what I said. I could be totally wrong though :)

Hi. I am a high school freshman who planned to take all the AP sciences in my sophomore year, and I initially felt daunting as I didnt know what resource did I need. However, after seeing your video and your enthusiasm in teaching biology, I am feeling less nervous about the exams! you are truly the best teacher and you deserve it!!!! wish you all the best sir

For question 1 d.i., I said that the number of copies of chromosome 8 would increase and my justification for d.ii. was correct. Would I likely lose the point for di since I didn't mention that the number of copies could also decrease?

[alphaanimated]

For part 1di and 1dii, I predicted that there will be a fewer number of chromosome 8 in the cells and I basically justified it as you said it (fewer would align & separate properly) but did not mention nondisjunction. But, my prediction was not the same as yours because you said there will be an abnormal number due to nondisjunction (more/less). Do you think that will get me 2 points, 1 point, or 0 points altogether?

For the last question, wouldn’t the values further right on the graph be slower, since the rate units are ms/codon. Is it showing that the more milliseconds it takes to translate one codon, the slower the rate or am I reading the graph wrong?

[Speedstrike]

Do you think that the curve for this year will be lower or higher then previous years? Like will we need less or more points to get a 5? How many points is it normally out of 120?

[joedassin]

For question 3 b), will mentioning reducing bias in the results count?
