June 2010: Biology

<p>So, just finished taking it and I must say, I was thrown off a bit. However, it was definitely easier than the AP Bio exam. </p>

<p>What did you guys think?</p>

<p>hey i just took it as well today. It was not that easy as I expected but I think i did fairly well. Scored a 780 on a practice test yesterday. So are we allowed to discuss the answers here?</p>

<p>I had a few questions…</p>

<p>The question about passing on plasmids in yeasts to daughter cells due to the presence of centromeres or something to that extent…was the answer because the centromeres allowed attachment to the mitotic spindle?</p>

<p>post your questions as well</p>

<p>I thought it went okay. The first few questions caught me off guard a bit and then towards the end (last 5 minutes) as I was checking my answers, I found 5 answers that I bubbled in incorrectly or misread, so both of those scenarios are making me feel a little edgy.</p>

<p>Not sure if the embargo was been lifted, but I don’t want to hazard anything just yet.</p>

<p>i dont know it was kinda hard but i only left 3 blank…
I think i got the question about circular DNA wrong… I said retroviruses and i think its bacteria.</p>

<p>For the people that did Molecular, what did you say about the testosterone injections? Did they make the testes smaller?</p>

<p>^that’s what i said. And i got the retrovirus one wrong too. damn. I also skipped 1.
So right now, im at -1 and 1 omit. I can’t retake this test because im saving my test dates for october and november for general SAT’s. I guess i could fit in Bio for december but very unlikely.</p>

<p>So, I definitely know for a fact that I got three questions in the beginning wrong :(</p>

<p>the commensalism/predation thing?</p>

<p>^ No, taxonomy.</p>

<p>I put Bacteria for the Circular one. </p>

<p>^ above, yes, I did for the Testosterone one.</p>

<p>if you guys did molecular, what did you say about the consumed DNA from other organisms? Do they become part of cell membranes?</p>

<p>oh, the cephalothorax and abdomen with no antennae was scorpion and the head with two antennae was crayfish. The tube feet was sea star and the last one was hydra.</p>

<h1>10, I definitely eliminated that choice. Does anyone remember what other choices there were?</h1>

<p>I said that the DNA is broken up into nucleotides and used to make our own DNA.</p>

<p>wait no… head with two atennae is butterfly… crayfish is gills?</p>

<p>Yeah, I pretty much messed that whole section up. Taxonomy is always my downfall…</p>

<p>^ I got crayfish for gills and hydra for two layers…</p>

<p>Oh crap. Screwed up the Taxonomy part so bad.</p>

<p>Yes, that’s what I put as well. Head with two antennae was the Butterfly one.</p>

<p>I put Crayfish - Gills as well.</p>

<p>DNA - I Highly doubt we consume it and make our own. I put it that we just eat it and turns into Co2/water : seems wrong as well, but the other options were just dead wrong.</p>

<p>What about for the antibiotics? Does it help us metabolize the bacteria or does it screw up their metabolization?</p>

<p>i put crayfish for gills as well. But i guess you are right about the butterfly. Damn. So thats -2 and 1 omit. ****</p>

<p>check this website. It agrees with my answer. Not very reliable but it’s true.</p>
