<p>Just wondering, would there be a big score difference between a person who took a biology class at school (AP, honors, regular, etc) and a person who didn’t (but bought practice books and had a tutor once a week for an hour for three months)?</p>
<p>Zhuzhupet: oh, then in that case, I also put niche too :)</p>
<p>hkim, i think it mostly depends on how much you studied/learned.</p>
<p>I guess it depends on how good your tutor is and how much you pay attention in class. For me, it was Honors Biology and books. I’m expecting a 720-790.</p>
<p>Edit: I also self-studied for the AP Bio. test.</p>
<p>@hkim0713 ^I second that. It depends on how much effort you put into your studying. I take an advanced Bio class in the 9th Grade but many other students who simply used books rival me in knowledge. I’m sure if you studied well you did fine (assuming you are the latter).</p>
<p>Thanks. 
What are your goal scores right now?</p>
<p>The question on how to tell how closely related 2 species are . . . .
Was it by comparing the DNA sequences, organelles, fossil record . . .
Sorry, probably was already discussed.</p>
<p>I’m almost 99% sure it is through DNA sequences. But what was it about the photosynthesis question?</p>
<p>@APManica I’m pretty sure that question said something about genetic relation so DNA sequence should be right. For anyone who took the E exam, what did you put for the question about the mole and their adaptations without eyes?</p>
<p>I put DNA, too.</p>
<p>MMA: I put that moles’ senses of hearing and smelling strengthened, and so did some other people in the forum, but one person said that it’s a different answer which I forget. I think you should look through the thread. What did you put?</p>
<p>Not trying to spam, but can anybody with M answer my question about photosynthesis?</p>
<p>morpheus what is your question?</p>
<p>For the similar species one I’m very sure the answer was genetic similarites. The wording throws you off. @morpheus44 which photosynthesis question?</p>
<p>I put that one too but I was debating between that one and the one that said a mutation gave them a adaptive advantage because I was thinking that evolution doesn’t act upon individuals and that a mutation seemed like a good answer.</p>
<p>I just realized—
All of the oxygen split off water in photosynthesis ends up as atmospheric O2. So the answer about incomplete splitting was wrong. I still don’t know what the right answer is though and this fact makes me very sad . . .</p>
<p>The one with the photosynthesis question using the oxygen 18 isotope, what conclusion could be drawn about experiment 1?</p>
<p>@hkim0713 could you give me a rough page number of where this question was discussed because I don’t really want to go through 30 pages.</p>
<p>MMA: Me too. I actually put down mutation first, but changed my answer to the one I chose. Do you think that the answer choice we chose is right?</p>
<p>To repeat:
Experiment 1 was:</p>
<p>6CO2 + 12H2(18 O) ------> C6H12O6 + H2O + 6(18 O)2</p>
<p>Yeah. I remember I was very sure of my answer to that question, I just cant remember the answers.</p>
