June SAT Biology E/M Pre/Post Test

<p>DAmn I omitted 8. ANd have atleast 4 wrong so far…</p>

<p>o yea, that’s what it was. I remember putting that.</p>

<p>For the photosynthesis/cellular respiration I II III type questions, did anyone get photosyn/cellular respiration only for the first two questions (about which produced O2 and used CO2 or something like that), then both for the last one (produces ATP)?</p>

<p>For E, what did you put for the diversifying selection?</p>

<p>For the question about fungi what did you guys get? I believe the answers were parasitic, autotrophic, and decomposers. I think i put both autotrophic and decomposers, but I don’t remember I switched it so many times. Wait no, I put all three. Yea I remember now, I thought fungi, like mushrooms, could be parasites on trees and such + they are autotrophs + decomposers. That would be considered parasitic right?</p>

<p>I put only cellular respiration for the third question because photosynthesis does create ATP in the light reactions but then that is used up in the Calvin cycle so I assumed that they wanted net ATP production? I might have gotten that wrong though, but that’s how I answered it.</p>

<p>@Tantoes, i said only parasitic and decomposers</p>

<p>@Apoc314, yeah I wasn’t sure what they meant either…</p>

<p>@catcat. I said only photosynthesis creates oxygen. Can someone verify?</p>

<p>I put parasitic and decomposers for the fungi question because fungi are heterotrophs, not autotrophs. </p>

<p>EDIT: Yes, I put only photosynthesis creates oxygen as well, morpheus44.</p>

<p>Yes, only photosynthesis created oxygen.</p>

<p>What did you guys get for the oxidizing question? It was cellular respiration right?</p>

<p>And for fungus, I put parasitic and decomposers.</p>

<p>Photosynthesis is the only one that produce oxygen(sure)
Respiration oxidize Glucose( I think)
And both Photosynthesis and respiration produce ATP (sure)</p>

<p>Oh crap i mixed up heterotroph and autotroph, that may have screwed me for the yeast question as well. >.<</p>

<p>^ yup it made a beautiful ABC staggering pattern</p>

<p>oxidation is losing electrons and bc photosynthesis is gaining electrons which is oxidation, cellular respiration is reduction</p>

<p>yeah i got the ABC thing too</p>

<p>@kim: I put directional selection</p>

<p>I think you contracted yourself. I am pretty sure cellular respiration is oxidation</p>

<p>Wait, oxidation is losing electrons so shouldn’t that be respiration then?</p>

<p>Yeah, it should be oxidation for respiration.</p>

<p>lol…
So how do you guys think you did?
I skipped 3 and probs missed 5. So maybe a 740ish?</p>
