<p>I hatteeeee the agglutination question. I understand that concept completely, I just didn't know the term "agglutination." This test ****ed me off completely, it does not reflect at all what someone in a biology course should have learned.</p>
<p>about the calvin cycle questions, i remember clearly my teacher stating that the term "dark reactions" was a misdeamoner (spelling, anyone?) and that it cannot occur in the dark, because it needs the reactants to act upon...</p>
<p>I put starch too, but after some googling (if that's a word) I think I'm wrong.</p>
<p>I searched on google: alcohol plants chlorophyll</p>
<p>I found many labs where rubbing alcohol was used in the procedure to separate and extract the pigments of chlorophyll. Even though it would make more sense for the alcohol to convert the glucose to a starch so it could identified by the Lugol's Solution (iodine) it's just not the right answer.</p>
<p>Here are some websites with the labs that had alcohol and chlorophyll:

<p>Quote from the last website:
1. To test a leaf for starch</p>
<pre><code>* Place leaf in boiling water to kill the cell and tear open the cell membranes so the iodine stain can easily enter the cells.
* Place leaf in boiling alcohol to remove the green chlorophyll so the final results can be clearly seen
* Dip leaf into warm water to remove the alcohol so the iodine stain can penetrate the leaf.
* Cover leaf with iodine solution to test for the presence of starch.
* Iodine turns starch blue-black.
* Those parts of the leaf that stain blue-black contain starch.
* Those parts that are yellow-brown (the colour of the iodine stain) do not have starch.

<p>That's pretty clear.</p>
<p>On the Bio-E section, how many levels were there in the food web with the hawk, grasshopper, shrew, and grass: 4 or 5.</p>
<p>I said 5. I believe that trophic levels are counted by animal species, not by "links" between species.</p>
<p>And also-- It would make no sense for boiling to turn glucose into starch. If I understand correctly, boiling would probably <em>disrupt</em> bonds. Starch is more complex than glucose, so for boiling to build/alter bonds seems strange. Furthermore, the plant naturally converts glucose into starch for storage, so it's not like the sole purpose of the boiling would be to do something the plant already does on its own.</p>
<p>I said boiling removed the pigments.</p>
<p>did anyone take ecology?</p>
<p>can anyone predit the curve?? i really want atleast a 720 and im afriad ive dont bad so far =/</p>
<p>for the trophic levels i put four, but their are five. I am so ****ed i did this dumb mistake. Produces, Primary Consumers, Consumers, Secondary Consumers, Tertiary...dangit..i just realized i missed produces when i was thinking..i hate this test..</p>
<p>Well, all you had to do was count the animals, not go over the various names for potential trophic levels. There was one more species than what Studying Stud said, methinks. It was grass, grasshopper, mouse, snake, and hawk.</p>

I was taught agglutination you just had a bad teacher:P haha jk</p>
<p>I'm gonna have to say now that PR is probably the best book for the test if you dont wana overprep. That Book+Common Sense+(No Bad Luck)= 800</p>
<p>The Calvin cycle CAN occur in the dark, but it doesn't have to. It used to be called the dark reaction, but they changed it because it wasn't appropriate. </p>
<p>Anyone know anything about the polyploid/diploid/monoploid question?</p>
<p>I think Barron's+Princeton is good, since Princeton didn't give me anything on the diseases and stuff, and Barron's didn't go over the plants too well.</p>
<p>"Anyone know anything about the polyploid/diploid/monoploid question?"</p>
<p>"why does e.coli have the system of activating galactidose at will?
...Why is it A? The only need for galactisodase is to BREAK DOWN carbs, so if you're not drinking milk (choice A), you won't need your lactose broken down. Unless I'm missing the point of galactisodase..."</p>
<p>Did you learn about the lac operon in e.coli? The point of it is that lactose acts as an inducer (or inhibitor? Am I mixing up my operons?) to turn the gene sequences on and off so that e.coli don't waste ATP making the enzyme needed to break it down when there isn't any there. That's why A was the right answer.</p>
<p>Influenza is a Virus- Common Knowledge
Malaria- (I just knew this b/c I'm sciency)
the penicillin question- Common Knowledge
and the bacteria question - imo somewhat hard but I'd have to say Common Knowledge for most kids on CC.</p>
<p>I thought the test was a joke, I just took AP Bio and read the PR book a week before (Religiously) - worked for me. (Broad Science Background though)</p>
<p>And imo soo much of Bio (especially the E section this time) was Common sense.</p>
<p>It sounds to me like I should have read PR</p>
<p>dangit..i didnt even kow influenza was a virus..so i put some random asnwer..and for penicillan i thought it was bactera..gosh darn..i just missed some! i want a 740+ and ill be happy..if i get a 700+ ill still be happy..</p>
<p>PR was imo the best route possible with a good knowledge of AP Bio. (If you have a moderate time constraint) And the quiz thing after every section makes memorizing really really easy. It's my favorite SAT2/AP prep book ever. =p It's been good to me.</p>
<p>guys why was the biology answers thread deleted? and world history wasn't? what kinda prejudiced moderator did that</p>
<p>Not fair really. Part of the thread appears on page 15 here.</p>
