January 2013 Biology E/M SAT Subject Test

<p>was the emphysema question in the general 60? because I don’t remember doing that question. was it near the beginning, middle, or end?</p>

<p>LOL I sound a bit frantic, but I’m freaking out here because I feel like I may have bubbled in the wrong numbers</p>

<p>Also, does anyone remember the choices for the bilateral symmetry question? I don’t remember it for some reason…</p>

<p>It was talking about the sequence except I believe there was one transcription. Inversion mutation is when one nucleotide gets flipped so it was when the sequence was the same but 2 nucleotides switched places. Point was when a nucleotide is mutated and switches to another nucleotide (I believe this one was 5’ATT but that could have been the other one). The other was transcription and it was 5’UAA from what I remember.</p>

<p>@AnnieZ I was confused by those early DNA questions too. The terminology threw me off, and I ended up skipping two of those. I probably only skipped 3 others on the whole test. As for the bilateral symmetry questions I think it asked for which organism(s) did not have bilateral symmetry and I answered adult jelly fish or something like that.</p>

<p>Ok good, so it was which one DIDN’T have bilateral symmetry. WHEW</p>

<p>Also, for the inversion one, I remembered it being when two nucleotides switched places, but some CC’ers have been saying it was the whole segment (like ATT to TTA) or something like that. Are there any other opinions on this?</p>

<p>Oops, looks like it is the whole sequence. Missed that one</p>

<p>I just remembered a few more lol</p>

<ol>
<li>Something about axon transmitting impulse - I put received a receptor or something like that</li>
<li>dogs with shortened tail don’t give birth to other dogs with short tails - I put it was an uninheritable trait</li>
<li>plants height - many genetic and environmental factors contribute to it (it was a I II III question)</li>
<li>potatoes turn green because it deters animals from eating it since the green leaves were poisonous</li>
</ol>

<p>Yeah, I found the potato questions to be a bit difficult as well. I went with the same as you for that one about them turning green to deter animals. There were two other questions with the potatoes I think, but I can’t recall them.</p>

<p>the bilateral symmetry question was “jellyfish and sea urchins” because they exhibit radial symmetry
the question somebody was wrong about… the disease was specifically stated as y-linked. there are many things associated with y-linkage, including male pattern baldness, so yeah it’s not THAT rare.</p>

<p>I remember the plant question was 1 and 2. It wasnt just the answer you put down ANnie/ZOndar</p>

<p>Wait, so what was the answer to the plant question?</p>

<p>It was I and II, pretty sure. one of the answers was many genetic/environmental factors control height, and then there was one more, cant remember but it made sense</p>

<p>I remember that question had kind of mutually exclusive options. like, the first one was that it was only affected by genetic conditions, one was that it was only affected by environmental factors, and then there was the answer i put down…idk</p>

<p>do you remember the question about the impulse on the axon? i remember putting down the answer with “receptors” in it, but i’m not sure it was right</p>

<p>Receptors was definitely correct. And I remember picking 1 and II. idk</p>

<p>Ok cool. And do you remember what the plasmodesmata question was asking about? I don’t remember that question for some reason lol</p>

<p>Also, was there a question about closed/open circulatory systems, and the answer was insects? Or was that only on a previous test?</p>

<p>yes insects. and that was the molecular section-- plasmodesmata.</p>

<p>Alrighty, I think I’ve compiled most of the Bio-E answers (trying to avoid studying for chem)…</p>

<p>can someone explain to me the answer " first 30 seconds more than 30 seconds"? and also bring up other answer choices to this one. ALso what was the intermediate height question asking? because if you looked at the graph asmall amount of black kips grew in both narrow and short, so an intermediate height would make the most sense for black kips only.</p>

<p>another answer: no nuclear membrane</p>

<p>also I’m fairly certain there were 4 DNA questions</p>
