January 2013 Biology E/M SAT Subject Test

<p>do you remember this one? asexual reproduction without genetic recombination</p>

<p>Usually, I would agree, but for some reason I explicitly remember the little blurb saying it was on the Y. It caught me off guard for that reason you just said</p>

<p>Nah, man I’m sure of it. It’s literally impossible to do crosses with genes expressed on the Y. But you maybe right, idk.</p>

<p>I’m sure it said Y as well.</p>

<p>Well, the y chromosome just determines sex friends. Its all of his daughters. end of story.</p>

<p>Dude, I guarantee you Y chromsome was not specified. ALL the question says was a male has a trait, crossed with a female, what occurs?</p>

<p>The father could not have given his son the condition, because he only contributes a Y chromosome to his son;[SparkNotes:</a> SAT Subject Test: Biology: Explanations](<a href=“SparkNotes: Today's Most Popular Study Guides”>SparkNotes: Today's Most Popular Study Guides)</p>

<p>Keywords in that: “for <em>this</em> condition.” Look, I’m not gonna argue. Believe what you want, but it is possible for a disease to be on the Y–unlikely, but possible. (Maybe I just read it wrong, but I was pretty sure Y was mentioned in the summary.)</p>

<p>I’m over 90 % sure Y chromosome was never specified, and if it was, oh well ,don’t think i did that well. Hopefully 660 +. Do you remember what you put for the one about advantage of asexual reproduction?</p>

<p>I think answer A but I honestly don’t remember. I just remember B, D and E didn’t sound right. (Maybe something about not having to have further genetic modifications? Idk)</p>

<p>YEAH thats what I put… do you remember any other ones?
no nuclear membrane for one i remember… </p>

<p>did you put not an inheritable trait for the one about shorter giraffes–cant remember the animals and also did you do ecology or molecular?</p>

<p>Hey guys </p>

<p>This was my first SAT test, so I’m just wondering, did you find it easier or more difficult than previous tests? I didn’t find it difficult, just took the whole hour to do since I was going slowly, trying not to make any careless errors.</p>

<p>For the question that asked about how many atoms in the reaction, I think the correct answer was 36 (even though I put 72), can I get a confirmation on this?</p>

<p>Also, there was a question (I think it was in the M section which I took), which involved a graph with mother, fetus and hemoglobin and one of the questions (which I don’t remember the exact wording) had five options of which two involved pH. Does anyone remember this question or what they put?</p>

<p>And for the questions about the two different birds on the different cliff heights/ledge size, what was the answer to how the birds react if you add an intermediate cliff height?</p>

<p>I took two practice tests from Kaplan and I got 11 wrong and left 1 blank on the first one (which Kaplan said is a 740) and 6 wrong, no blanks on the second one (which Kaplan said is a 780). Is this generally a good indication of the actual curve the test has? The questions on this test where a little bit less detailed than Kaplan’s questions, but the structure of the test itself was actually pretty close.</p>

<p>Thanks</p>

<p>Oh yeah, and the question which involved 8 chromosomes (or was it 8 genes), was that the same question as people are saying the answer to was 8 genes code for 8 proteins? Are you guys sure that’s the correct answer?</p>

<p>@CanadianEuropean</p>

<p>I think it is (according to the one-gene-one-polypeptide hypothesis)</p>

<p>To go back a few post, I do recall a blurb about the disease being on the Y chromosome. Hence every son would get it, but that, of course, contradicts the fact that the Y chromosome typically doesn’t carry much of import. Thus, I’m not sure either.</p>

<p>Hmm maybe i missed the blurb then. Still makes no sense, but on to a different topic. Can some of yall help compile ecology? im having a difficult time remembering the solanin questions-with the potatoes.</p>

<p>And just as a side note, on the intermediate height question, i was pretty sure the black one would grow on the intermediate, because it didnt grow on the lower one or the higher one. just speculation</p>

<p>anyone else put fetal grew faster than mother till birth</p>

<p>For asexual reproduction I put no genetic recombination for favorable traits
It was 36 atoms - the question was how many atoms take part in reaction
I put fetus bound more O2 at lower pressures than mother - I specifically remember not putting fetus grew faster</p>
