<p>I ended up doing both the ecology and molecular sections because I had so much times. And yes, it was that cereal, fruits, and vegetables, since they are producers, the trophic level containing the most energy.</p>
<p>the one with the bat's wing ? convergent evolution?</p>
<p>yep yep convergent</p>
<p>electron transport system was basically the easy way to solve that problem.</p>
<p>hhhmm.... thinking of another question.</p>
<p>for that last two on molecular, it was the activation energy required to bring two reactants togther?</p>
<p>and then the last Q... #80... it was, I think, that oh nvm, i forgot the last q...</p>
<p>Wait what was the bat one again?</p>
<p>Two of my friends cancelled their grades on SAT Bio today. The test had way too much genetics. It was ridiculous. Especially those questions in the beginning stumped me. The molecular part----was good. I make no predictions, but the test was harder than i expected.</p>
<p>last Q on molecular was something like "how do enzymes affect the reaction?". answer was they lower the activation energy (Ea)</p>
<p>yes enzymes lower the Ea.</p>
<p>Ye, that was easy...there were much harder ones!!!</p>
<p>This is a stupid question, but the haploid question in the beginning stumped me, cus at first i thought it was 8...u know...4 haploid, 8 diploid......but there was no 8! So i eliminated 2, 25, and 50 i think it was. Which was it....16 or 4???</p>
<p>pretty sure it was 4</p>
<p>Hmm...others i asked said 16....weird....</p>
<p>Yes i thought it was hard too. I was expecting questions on labeling structures and plants/flowers, but there were none at all.</p>
<p>Cus the key part was chromatids...and u gotta remember homologous.</p>
<p>BTW...there is no curve right? Cus i didnt expect this.....just like u said....there were no plants, not even organ structures! ***! We spent like so much time on that and review books cover a lot on physiology; there was none of that! Except they used "colon" to trick ppl instead of large intestine.</p>
<p>For the one about chromatids, it was 16. You end up with 4 daughter cells after meiosis, and each of those has 4 chromosomes (so 4 x 4 = 16). DNA doesn't get replicated in between meiosis so what you have in the daughter cells has to have been in the parent cell.</p>
<p>what's aggluntination?</p>
<p>I agree with altairaqua, the answer was 16.</p>
<p>Agglutination was the answer for whichever question it was- I forget what it asked, but it was the answer.</p>
<p>YES i guess 16!!! agglutination is blood platelet blockage due to different blood type mixing :)</p>
<p>oh crap, i put 4 cuz I meant 4 for each one</p>
