<p>Does anyone remember anything on the very end of the Bio - E about birds and the number of offspring, and how many would survive?</p>
<p>Was it, remain at 4-5
Most would survive at 5
and was the graph like a parabola looking line peaking around 4-5?</p>
<p>Appreciate it.</p>
<p>yupp your rightt</p>
<p>Nah, marsupial one was long gestation period. You’re right about the other two assumptions, I think. Morphology is wrong because the crabs could look almost identical, embryo development would be REALLY similar. DNA would be the most accurate distinguisher of diff species, IMO</p>
<p>Yeah sorry, that’s what I meant to say. It IS gestation. I got that one wrong 
But I don’t feel too bad since I had no idea about that.</p>
<p>“Was it, remain at 4-5

and was the graph like a parabola looking line peaking around 4-5?”</p>
<p>That’s what I said.</p>
<p>wait what was homology??</p>
<p>Ugh… I feel like killing myself.
The first 60 questions were totally centered on ecology, and they were shady, too. I didn’t expect to get 2/3 biome questions wrong in the beginning! On the other hand, the molecular and genetics part was retardedly easy. I smell CollegeBoard turning away from logic and embracing pure memorization… I skipped 4~5 and probably got 5 ish wrong. ■■■</p>
<p>Dang. Now I feel even less confident about my score.
Omit 2, Missed 3. (What actual score would this be?)</p>
<p>I still don’t get the crab populations one; why is it substrate? What were the other choices?</p>
<p>^ yeah substrate or the other one that im forgetting as well…?</p>
<p>Definitely substrate. The first three were ruled out, because they were the same distance from the tide line. The other might have been “den burrow density” or some crap, but that would have taken some wild inference to actually arrive at that conclusion. </p>
<p>One group of crabs were chillaxin in mud, and the other in sand. That’s the only one you can infer.</p>
<p>YAY one question right! woot! =] lol</p>
<p>What do you think a -7/-8 would be?</p>
<p>-7/-8 probably around a 770. </p>
<p>For the question about the pedigree chart with free earlobes, it’s 1/2 probability the daughter has free earlobes, right?</p>
<p>yes its 1/2
and mowmow is it really 770?!?</p>
<p>Yes, if the curve is the same as the test in the Official College Board SAT Subject Test study guides (the other big blue book). I have it in front of me right now, 73 and 72 out of 80 are both 770s.</p>
<p>how about raw score of 70?</p>
<p>Oh well that would be 750. As would a raw score of 69 be 750. So I suppose you can assume you got a 750.</p>
<p>yay i want a 750+
you think the curve cud be even better?</p>
<p>Possibly. Depends on how the rest of the world does on stupid ecology questions that made up most of the 60 main question section. Honestly, who the hell studied for Marsupials =/ </p>
<p>I thought it wasn’t too hard or too easy, but others think differently. Possibly a more generous curve than that, IMO.</p>
<p>what was the answer for the one about acid rain?
i wasnt sure i put something about methane because the others didnt make sense at first. but now im doubting my answer… could it have been burning of fossil fuels, i just thought that contributed to the greenhouse effect so i completely ruled it out</p>
