@CollageWhat But couldn’t 2nd consumers consume primary consumers? Or am I just going about the question wrongly?
@mochilate1897 Didn’t it ask which two animals likely would not be at the same trophic level? All the others were both herbivores or both carnivores so it was possible for them to both be primary consumers or secondary, etc… For this one, however, they cannot be at the same trophic level because one HAS to be a primary consumer (deer) and one CANNOT be a primary consumer (wolf). If it asked if they’re in the same food pyramid, I agree that this would not be an answer.
@CollageWhat Ahhh you’re right, im pretty sure that the question said trophic level but I must have read it as food pyramid.
@CollageWhat it was Wolf and Sheep
@RybkaShredder Yes it was.
@RybkaShredder Ok yeah, wolf and sheep. Sheep also are herbivores, to my knowledge.
@mochilate1897 to answer your question about the difference between marsupials’ and placental mammals’ embryonic sacs: both types of mammals have them at some point, it’s just that marsupial offspring exit the sac at a less developed stage than do placental mammals.
I’m taking IB Bio next year. What prep book is best for SAT Biology?
what did you guys get in the M section about specific gene comparisons? other than the rRNA one, I feel like there was another similar question next to it with the same choices, like hox1, etc???
@MrAustere I used Barrons, because I heard if you do well on its practice tests, you’ll get a way higher score on the real thing. But I thought the actual thing was way harder than Barrons. Also I heard that some of the exact questions from like Kaplan or PR (I can’t remember) was on the real thing this year. Maybe try a combination.
@samsunguser Thanks!
what did you guys put for the question that asked doubled in cell mass? it was part of the matchings
@SpaceX it wasn’t matching but A was the answer, S phase
Maybe we’ll get a good curve
Bio has a hard curve to be honest. It’s 80 questions, -10 should be an 800
@MrAustere Kaplan’s and Princeton’s practice exams were NOTHING like the real exam. They test you at extreme details and have much longer experiments than the real one will have. As for content, I don’t really know much about the IB curriculum, but I took AP Biology and I used Princeton to study things on the exam that we didn’t cover (plant reproduction, embryology, skeletal system, major hormones/glands, etc.). If I could go back in time, I’d probably do the Blue Book official practice test, skim through Barron’s to review things I’ve learned (and do the practice tests), as well as using Princeton for another review and filling gaps between SAT and AP.
Guys the second set of questions is B, Natural selection, A, Mutation, D, Genetic drift.
@catsthatbarkk yeah i think that’s how i remember it. mutation for the one that was like a new trait randomly appears? and i can’t remember if i accidentally wrote genetic flow 
@Collegewhat all I remember is that the second one was mutation, I don’t remember what the question was though.
@catsthatbarkk I’m pretty sure the answer was genetic drift. It asked for a recessive trait randomly disappearing
I think I have around 4-5 questions wrong. Didn’t skip any. Does anyone know what that score would be?
