OFFICIAL SAT II BIO June 2..

<p>I don't exactly remember those questions from the M section about acid, Co2 test, and breath. But I think you had to choose the 2 tubes from the first indicator (the one that tested for acids better and was the top of the table). One tube had to be a known acid and the other the student's breath.</p>

<p>wait was the answer to the immune system question in M proliferation or differentiation?</p>

<p>It was the one about "already existing lymphocytes proliferate".</p>

<p>was there ever a master list posted in the first four pages to begin with, or did i totally imagine this?
because going back and forth and debating these questions just might give me an anxiety attack, haha</p>

<p>for the liver question, the liver does make red blood cells</p>

<p>the answer was detoxification of urea or something like that, the kidney does that i think</p>

<p>u r sure bout that? that theliver make rbc...i thought i read that sumwhere...thats why i doubted myself...but i thought rbc was in the bone marrow....</p>

<p>they are usually made in the bone marrow but can be made in the liver too</p>

<p>Browncow- Yes, there was such a list, but it was deleted shortly after it was posted</p>

<p>aigght so whats the correct answer to the liver prb?</p>

<p>The curve in the books don't mean anything for the actual tests. The college board first gets every raw score, and then sets the curve so that they get a similar range of grades to every other time they give out that subject test. Otherwise, with the same curve out of some book each time, people taking an easier test would have a huge advantage for college applications.</p>

<p>Ookanuba is the master key lady. She (i think) did the same thing for the May Bio and Chemistry tests.</p>

<p>upon further inspection in my book, the liver does deaminate as well so whats the answer?</p>

<p>umm. the liver question answer was the red blood cells. 95 percent positive.
Wikipedia excerpt:"In the first trimester fetus, the liver is the main site of red blood cell production. By the 32nd week of gestation, the bone marrow has almost completely taken over that task."
Okay..so it does it in a fetus.. but the BM takes over practically the whole process. Don't read too much into these Q. lol</p>

<p>Hey guys wat was the answer to the one with Linked Genes, i put all three, I, II, III is that rite?</p>

<p>And the question about which of the following factors and then something about population density was the answer severe weather!</p>

<p>Edit: Whats a score of 3 omit and 7 wrong!</p>

<p>I didn't take the E test, but I read through it after finishing the M section. Yes, severe weather was the answer.</p>

<p>yes! so wat is a score of 3 omit and 7 wrong?? anybody??</p>

<p>^ I'm not sure. I'm ALMOST is the same boat.. I ommited three ..but i got a couple wrong..idk how many though.
Linked genes..it was only two of them.</p>

<p>i highly doubt this, but possibly the answer to the liver q is -does not store glucose. it stores glycogen, which is a form of glucose, but is still something different. plus we have established that the liver does indeed at times make rbc's.</p>

<p>for the linked genes one...i'm pretty sure it was all three...i don't remeber the choices exactely..one was: it was on the same chromosome...and one was like they could be inherited separatly or crossed over.....i went home and checked the ap bio book...it said linked genes are linked and inherited together ASSUMING that crossing over have not occured...meaning that crossing over can occur between linked genes...though they are not linked then anymore...hoped it made sense..is there aynone who remembers the 3 choices? thanks that would be helpful...</p>

<p>after doing research:
liver makes bile
liver detoxifies
liver stores excess glucose
liver deammonizes ammonia to make urea or some jazz like that
liver DOES NOT normally make rbc</p>

<p>three choices for teh linked genes:
same chromosome
crossing over can occur
located only on sex chromosomes (NOT TRUE)</p>
