<p>"for that question about burning glucose and respiration, wasn't it that respiration makes more energy because i thought just burning glucose = fermentation and respiration makes more energy through the electron transport and what not...is that wrong?"</p>
<p>burning glucose produces more energy, just not usable energy, the glucose combusts... i think it's the one with lowering the temperature..</p>
<p>So was the answer that simple combustion and oxidate phosphorylation burns at different temperatures?</p>
<p>shrugs, that's only what i think...</p>
<p>and what was that cat/opposum/snake graph one</p>
<p>There were only 2 possible answers
-mammals regulate heat differently
-something else about cold-blooded</p>
<p>what's the other one?</p>
<p>those are the 2 -.-</p>
<p>like what's the something else?</p>
<p>what was the answer to the karyotype question that asked talked about trisomy? was the answer 25 or 49 ?? i think i read the question wrongg</p>
<p>49, a lotta people read the question wrong, i changed from 25 to 49 in literally the LAST MINUTE</p>
<p>mammals regulate heat differently btw</p>
<p>oh yeah guys, i think the karyotype one will be a field test question.
it's supposed to be 23, not 24, and 23 wasn't even a choice.
23 and 46.</p>
<p>I was looking for 23 and had to choose 24 since that wasn't an answer, but it said it was a karyotype for a normal cell, so it should've been 23.
Collegeboard screwed up . . . </p>

Most of your body cells (known as somatic cells) have 46 chromosomes, in 23 pairs, with one from each parent.

<p>Um, no sorry. It was 48 and 24.</p>
<p>i know, i put that too, but its supposed to be 23, 46, thats the general consensus in modern biology today. NORMAL CELL HAS 23 pairs, ask any doctor</p>
<p>"i think i put erosion for that one.
wut were the choices?"</p>
<p>1231--I looked it up later. It was oxygen depletion. -_- I had that originally and changed it. <em>smacks forehead</em></p>
<p>About the karyotype---Who said it was a human karyotype?</p>
<p>but did it specifically say it was a human cell?</p>
<p>and also... sarorah... are you sure? because i read the question through several times and i kept getting the impression they wanted 25... shrugs.</p>
<p>hold on
for the why was the woman infertile question, isn't it just I because III basically said that the vagina was creating a hostile environment for sperm, which it does anyway right? that's why it has the semen to protect it...at least i thought...</p>
<p>you know what? i say collegeboard should just give us all 800s :P</p>
<p>totally agree</p>
<p>god knows i need it</p>
<p>ya it was a karyotype of a chimpanzee</p>
<p>I also had no clue what trisomy meant.... (never mentioend in PR)</p>
