<p>@Morpheus - I don’t exactly remember, but… was the fact that plants could use O2 as well as 18O2 one of the answers? what were the choices…</p>
<p>btw, the DNA was winded up, so the answer was definitely the one where it was
5----3
3----5</p>
<p>@catcat I think some were ; excess water is taken, something about the oxygen from water being incorporated into the glucose. Again, I don’t remember this well. Can someone help?</p>
<p>I am pretty sure adding phosphates to bodies of water ultimately increases diversity. Sure, some fish might die, but masses of a wide variety of bacteria and fungi appear. And the key word was “species diversity.” It might of killing like 7 different species of fish, but then there are hundred of species of diversity.</p>

<p>This source claims that it is OVER 4,000 NEW SPECIES OF ALGAE. There you go. ;D</p>
<p>Fungi are heterotrophs. End of Story.</p>
<p>what do you think the curve is going to be for this test? maybe 4-5 questions wrong is an 800?</p>
<p>Fungi are heterotrophs, but they often share symbiotic association with photosynthetic organisms. This was a trick question, but the answer is heterotrophs. Does that clear anything up?</p>
<p>More water is present than is split into oxygen? Was that one of them?</p>
<p>^ I think so</p>
<p>“The oxygen given off by plants comes from water.”
- source AP Bio. book</p>
<p>Might clear some stuff up.</p>
<p>i think another one was that CO2 carbon (oxygen??) is incorporated into glucose or whatever. totally forgotten.</p>
<p>@hpyscm - haha we had a big debate over the DNA strand thing. I still think it was C, which was
5 ---- 5
3 ---- 3
since it was a wound DNA and that was possible.</p>
<p>I’m thinking 4 question curve is safe bet.</p>
<p>^ That’s what I put because the o18 originally present in water went to the glucose, if I remember correctly. Did others say this as well?</p>
<p>Okay, so for the caterpillar peak question, the answer was interdependence or niche partitioning? I was really confused between the two choices.</p>
<p>@hkim: i put niche partitioning because one of the species was able to survive even after the other species’ death</p>
<p>Hi guys, just curious. You know the question on what molecule a reptile would excrete in a hot and dry desert? I figured that the reptile would have to conserve water, due to it’s enviornment. I put uric acid (pastle like substance as opposed to normal liquid urine). I fanyone remembers this problem and was sure of their answer, please tell me what you put.</p>
<p>uric acid, yeah</p>
<p>@wopoccs: my ap bio book says that birds&reptiles excrete uric acid. (:</p>
<p>Zhuzhupet, are we talking about the same question? Are you referring to the question with two graphs (where one line went up and the other went down) or the one from the ecology section about caterpillars and bird?</p>
<p>Wopoccs, I put uric acid too. :)</p>
<p>@hkim: oh sorry, my bad. i didn’t see a specification and i took M so i assumed that it was the only problem with graphs and caterpillars</p>
