<p>Question:
I know a lot of the questions here are on human anat.
The test isn’t constructed so heavily around this topic, however, correct? My teacher hasn’t put emphasis on human anatomy at all…</p>
<p>^We haven’t even finished covering human anatomy yet, but… according to some review book, approximately 10-15% of the exam is usually comprised of this topic.</p>
<p>Looks like Barron’s made a mistake in the questions above. Digestion is completed in the small intestine, but according to the answer key the only correct answer for #3 is the esophagus. It seems like large intestine should be right too though, unless egestion counts or something.</p>
<p>hey anyone has 2008 ap biology multiple choice questions???</p>
<p>and answers??? please</p>
<p>Regarding Post #378:</p>
<p>1) D
2) E
3) B
4) D
5) D
6) C
7) E</p>
<p>Those are probly right above.</p>
<p>Describe Tay-Sachs disease</p>
<p>Isn’t that the one that results from a defective lysosome and as a result, lipids accumulate in nerve cells and that becomes problematic.</p>
<p>Oh, it’s autosomal recessive.</p>
<p>I really need to brush up on diseases.</p>
<p>
</p>
<p>Yes, that is exactly what it is – premature death of nerve cells due to the accumulation of gangliosides. It is particularly prevalent among those of Ashkenazi Jew descent.</p>
<p>Mifune do you have photographic memory? o.o</p>
<p>How do you study and retain so much ? JW</p>
<p>“Mifune do you have photographic memory? o.o”</p>
<p>^Haha, he definitely does. Thank goodness we never have know any of these topics to that level of detail for the AP exam.</p>
<p>
</p>
<p>… I don’t really have anything to say. Except that I’m very, very jealous of you!</p>
<p>
</p>
<p>I think my memory is pretty good - but quite far from perfect. Actually, what I stated in #389 was basically recasting what xxrunningonempty had posted.</p>

<p>So for the ones that I did answer, how did I do?</p>

(e) a PO2 group, deoxyribose, and thymine</li>
</ol>
<p>Use the following five choices for #2-6:
(a) Lipids
(b) Peptide bonds
(c) Alpha helix
(d) Unsaturated fatty acids
(e) Cellulose</p>
<ol>
<li><p>Contain one or more double bonds which “kink” the carbon backbone.</p></li>
<li><p>The major class of biological molecules that are not polymers.</p></li>
<li><p>Linkages between the monomers of proteins.</p></li>
<li><p>A secondary structure of proteins</p></li>
<li><p>A structural carbohydrate found in plants.</p></li>
<li><p>If three molecules of a fatty acid that has the formula C6 H22 O2 are joined to a molecule of glycerol (C3 H8 O3), then th resulting molecule would have the forumula
(a) C48 H96 O6

</ol>
<p>3 is transmission electron microscope. Both scanning and transmission are powerful, but scanning is usually used to study the surface of cells, while transmission is used to study the internal structure of cells.</p>
<p>6 is the repressor. </p>
<p>10 is C, the tracheids.</p>
<p>11 is D, root pressure.</p>
<p>12 is C, the frequency of the impulse. Think of pain like a heart pulse. The greater the frequency, the greater the pain or feeling. </p>
<p>13 is D. This one seems hard at first, but if you recall B cells and T cells, you’ll remember that cytokines are a large part of their function and that B and T cells are part of the specific immune system. </p>
<p>14 is B. The plants are probably releasing toxins to hinder other plants from crowding them out.</p>
<p>15 is E. You were on the right track, since the mating dance is a fixed action stimulus. But the releaser is what begins the FAS, and that would be the bobbing head.</p>
<p>You did very well on the ones you didn’t skip. I chose hard, specific ones on purpose from a variety of chapters.</p>
<p>My answers to yours would be:
- B
- D (?)
- A
- B
- C
- E
- No idea, blind guess would be A
- B
- C</p>
<p>Thanks for the explanations. #12 and #13 I didn’t know because we haven’t yet covered that material. I have it in my schedule to cover it today, in fact.</p>
<p>Of the questions I posted: You only missed #7. </p>
<h1>2 is D because unsaturated fatty acids contain one or more carbon-carbon double bonds (which yield kinks), whereas saturated fatty acids contain no double bonds.</h1>
<p>With #7, recall that to join molecules by dehydration synthesis, one molecule of water must be removed. Since there are four molecules involved (one glycerol and three fatty acid chains), there will be three bonds, and therefore, three molecules of water must be removed. To solve, add up all the C, H, and O in the three fatty acids and the glycerol. Then subtract 6H and 3O to account for the three water molecules. The answer is (C).</p>
<p>I didn’t realize animal cells can plasmolyze lol</p>
<p>^ :eek: !!! 
</p>
<p>Both plant and animal cells can. :)</p>
<p>Thanks for the explanation for 2 and 7! Dehydration and condensation reactions confuse me for some reason. I get them all mixed up. Combine that with the critical thinking that 7 required and you’ve turned my brain to mush. I have to go back and review that.</p>
