i was pretty confused with that question initially. however, i interpreted it as saying that the larvae all begin with the same genomes, and i talked about how the mussels develop the allele, which is probably wrong. now that I think about it, it makes more sense to say that once that mussels are dispered to a favorable environment, they attach to a rock nearby. I hoenstly dont even know anymore.

yeah prokaryotes have no introns. did you guys put that the length would be 15kb? due to transcriptoin and translation occurring simultanesouly in prokaryotes, so no processing goes on.

I dont think it said site, but i said near the higher salinity locations since presence of lap94 in fresher water would cause lysis of the cells and a disadvantage. For the direct energy source, the answer is the endosperm since it is an angiosperm seed right after germination.

for the first grid in i couldn’t figure out how to find out the volume of the second cell. i found the surface area…but how do you find the volume w/ a 4 function calculator. idk maybe i just suck at math

also, for the grid in, putting 1/2 still works even if the question asked for a decimal answer?

yeah the bacteria one and mussels one were both 10 pts each. the meiosis one, the dry mass one, the prolactin, rna splicing, and 2 more were 3-4 points each.

@brixtonshifty86 i think so, that’s what I did - they said a fraction would work too, I think?

would it be incorrect to say that the bacteria stopped growing because they reached carrying capacity? i forgot about the nutrients running out oops

oh wow youre completely right, i forgot about that compeletely. thank god i said they would be in higher salinity areas instead of that. what did you right explaining the disperal of them?

test was easy like cheesy bread. 90 percent of the test was ecology or graphs. Will admit the frq was a bit difficult, but still easy cheesy

@glassflowers yea in the page before it said you were able to do either, just a little worried cause the question specified for decimal, but it shouldnt matter because they should detect that 1/2 equals .5 and be fine with it.

@shiftydraw omg I also got 9:3:3:1 for the linked gene cross…there were 2 mins left on the clock and i just put this because i remembered seeing this vaguely in the barrons book. praying its right :slight_smile:

yeah overall test was very easy, which was sorta expected based on the 2015, 14 and 13 frqs that I did. all similiar, much easier than what I wouldve thought, wasted time trying to memorize specifics of respiration, photosynthesis and all that.

@peachypo101 easy. Told u ratio was equal. Therefore just double the answer. Did that question without a calculator too cuz my teachers f’ed up

@luckydoggy1234 dammit

Wait will 1/2 work for the .5 one?

@HL3535 I think so

4995 for the bacteria growth? no idea how to do the logistic growth grid in, just got 200 somehow. was that biomass energy transfer something like 2/20? around 11%?

Ok, anyone else find time to be an issue? I finished MC with like 20 minutes left and FRQ with 15, but a lot of my class didn’t finish

Time was a huge issue for me. I didn’t even finish FRQ
