June 2010: Biology

<p>@Mathlete: I’m at about 770 from what I can see and I read straight through McGraw Hill and Barron’s, used some sparknotes things, and PR tests. McGraw Hill is very good, but Barrons is still better, Hill had a lot of the obscurer stuff/alternate terms that were on this test.</p>

<p>So far I’ve confirmed two wrong, and I think two omitted.
And one possible wrong. D:</p>

<p>Well if anyone wants me to see what their score is based off the old released collegeboard tests, just say so and I will look for it.
I’m assuming that I do not get more then 15 wrong with 3 omitted, which is a 670, based off the old test.</p>

<p>Do you think I should cancel my score?
Worst case scenario - I think 10 wrong for Bio-E?</p>

<p>I still have next year (junior year)</p>

<p>No, I don’t think so, 10 wrong none omitted? That’s a potential 760 depending on the curve</p>

<p>there was something along the lines of recessive genes show up less in polyploid plant than in diploid plants right?</p>

<p>and mutations in gametes are necessary to be important in evolution?</p>

<p>so far im at 2 wrong, none omitted…</p>

<p>phew</p>

<p>i eliminated it to sea star and the scorpion and split the 2 remaining answers</p>

<p>i mixed up in 10-14 about the structure of plants- forgot where the xylem and phloem was :(</p>

<p>I said that it will be taken out by natural selection, or disspear or something like that, since the diploid is shown more on land than the haploid, and the haploid won’t survive anyway with a recessive gene. At least that’s what it said in PR.</p>

<p>a recessive mutation in polyploid should show up more because it has more than 2 chromosomes whereas a recessive mutation in a diploid would only show up in 2.</p>

<p>does estrogen target the ovaries or the uterus</p>

<p>this may seem obvious but i just need confirmation</p>

<p>i put ovaries because uterus holds the embryo for 9 months, why would hormones be directed there</p>

<p>What was the answer for the polyploid one?</p>

<p>Yeah, estrogen is aimed at the uterus.</p>

<p>What about the fly? Someone said it was mimicry but I said directional selection…</p>

<p>The answer was mimicry, I don’t remember the question exactly but I know mimicry was only on the test once and it was the answer.</p>

<p>I think im gonna get around 680’s or 650s… should i cancel? i want to get into a competitive state school… should i cancel and retake to try to get 750? or just leave it and see what I get and then if i don’t ill just retake.</p>

<p>So should i cancel and retake or see score and then take? will it hurt me if i get 680 and 750?</p>

<p>1, 2…i know i got 4 wrong and counting + i ommitted 2</p>

<p>when does people start canceling their scores? at 10 incorrect, 15 ?? etc</p>

<p>oh, allright. I thought it was directional because it said something about escaping predators. </p>

<p>if I get 6 wrong (playing safe here), what will my score be?</p>

<p>When will we get the scores? I just hope i did well.</p>

<p>I said that it will be taken out by natural selection, or disspear or something like that, since the diploid is shown more on land than the haploid, and the haploid won’t survive anyway with a recessive gene. At least that’s what it said in PR.</p>

<p>Was that a choice?</p>

<p>przgonna, did you omit any? If not thats a really good score. I’d say 780ish??</p>

<p>For the polyploid ones I put that it would be more prominent.</p>
