October 2009 SAT II - Biology

<p>haha.
jake: i put desert too, unfortunately.</p>

<p>oh i meant to say northern coniferous, which yes, is characterized by needle-leafed trees.</p>

<p>i think someone brought this up earlier, but i’m still confused by the solute question. people said olfactory/taste, but how is that different from the other sensory receptors that were listed? also, does anyone even remember the wording of the question?</p>

<p>i picked coniferous… and yeah its the same as a taiga</p>

<p>alrighty 6 wrong 1 omit :(</p>

<p>dangitt…another question wrong =[
and yea…it was definitely coniferous (deciduous was not an answer choice)</p>

<p>whats every1 raw score loll
im now a 72</p>

<p>cloisville: i actuallly dont remember the exact wording of the solute question, but i remember my reasoning was that the other options didnt make sense to me, cause u can actually tell when there’s a difference in solute concentration with olfactory/taste (like if its too salty or something) but not with like pain receptors or receptors in the retina, or in the other choices</p>

<p>a 72 is still a 770, according to the blue book. i’d be satisfied with a 750+</p>

<p>bw - was the question really asking you how you could non-empirically measure solute concentration? i thought it was different. but now i really don’t remember what it asked.</p>

<p>Hey cloisville, can you post up the curve (or some of it) from the blue book? I’d really appreciate it :).
Thanks</p>

<p>clois ru serious? it is? and yea id be happy with a 750+
how many wrong/omits have u got so far :/</p>

<p>how old is the blue book anyway? plus those scalings were only for one test. you think the scalings have changed since then?</p>

<p>yeah, the scale is only for that specific difficulty of that test, and also for that specific group of students who took the test.</p>

<p>but as listed, for molecular, the raw score to scaled score is:
77-80: 800
75-76: 790
73-74: 780
72: 770
70-71: 760</p>

<p>and so on.</p>

<p>so hopefully we all screwed up so the curves good lol</p>

<p>LOl yes! i hope they perceived the test to be hardd. does any1 think they got an 800?</p>

<p>WOAH. 72 is a 770 ?! OMG. Clois I think you just made my day. But I probably still made some careless mistakes. Ugh. I really hope the curve is generous this time.</p>

<p>HAHAHA strawberri
we think alike. we both chose desert and we both have a max raw of 72
and we both were happy when clois posted that curve</p>

<p>YEP.
But I’m still so irritated ! This test was NOT what I expected it to be.</p>

<p>SAME! its got to be a generous curve! harder than i anticipated</p>

<p>So this is what we’re at so far:</p>

<ul>
<li>rRNA (for two questions)</li>
<li>Measuring solutes: Olfactory/Taste glands</li>
<li>Chordates for the one with the notochord</li>
<li>Prarie Dogs: 1 square mile and extrapolate</li>
<li>Calcium for the muscle contraction</li>
<li>G+C: Triple bonds (only one that was even correct biologically)</li>
<li>Photolysis (can’t remember which question)</li>
<li>Northern Coniferous, Rainforest, Tundra (don’t remember which order)</li>
<li>G+C Picture: Choice A</li>
<li>G+C Temperature of strand 2 at 50%: 72 degrees</li>
<li>Genetic drift for one of the questions</li>
<li>Motor neurons for the gall bladder (they’re the ones that control muscles and glands; if you cut off sensory, then the gallbladder wouldn’t be able to send impulses to the nervous system, which is opposite of what they’re testing)</li>
<li>For the picking of organs, in no particular order: Heart, Pancreas, Liver, Lungs and 1 more</li>
<li>For the aquarium one (I think): Optimum function of the enzymes</li>
<li>Pituitary Gland: Hypothalamus</li>
<li>Mitosis: To make sure each cell gets a copy of each chromosome</li>
<li>Arthropods: Evolutionary Success</li>
<li>Enzyme Substrates: CO2 and H2O</li>
<li>Crab Question: Live in same area</li>
<li>Specialized Muscle/Nerve Cells: They only use specfic genes</li>
<li>For the plants questions: Phloem, Guard, Cambium cells (not in order)</li>
<li>True Breeding: The phenotype choice (B)</li>
<li>The structure at the beginning: Lipid</li>
<li>Hot Springs order: 3-2-1</li>
<li>Where the egg gets fertilized: Fallopian Tubes</li>
<li>Eukaryotic, chitinous walls: Fungi</li>
<li>Primary Consumer: Deer</li>
</ul>

<p>What did you guys get for the epithelial cells in the gut? And what did you get for the bird that had a brightly colored male? I put vision and diurnal or something like that.</p>

<p>For the aquarium question, there was one about color. Did anyone else get green?</p>

<p>And one more…what did you get for the Darwin question? I totally blanked out on that; I remembered something about natural selection so I wrote extinction is nature’s way of weeding out the weakest animals.</p>

<p>I think the compare the marsupial and mammal question was to compare morphology. They’re internal development is going to be pretty similar, since all chordates have some identical characteristics in their embryos. I think any single individual is going to have different DNA, so you can’t compare that. If you compare morphology (their structures), it makes more sense. You can’t confuse a human with a kangaroo by just looking at the structures.</p>

<p>I felt this test was waay easier than June’s.</p>

<p>So far my raw score is 77. 2 omit, 1 wrong. :/</p>
