October 2009 SAT II - Biology

<p>i really hope i get 750+ :confused:
any other questions?</p>

<p>clois: i chose sensory, but ppl say otherwise and i believe they are right. for the other q, it was 0, 0, 0, 6, 18 (zeroes were all animals, corn was 6, 18 was ecoli)</p>

<p>Its sensory. Because if the motor neurons were cut off, the gallbladder would not release bile, even if a message was transmitted. However if the sensory neurons were cutoff, then there would be no message sent to the gallbladder, and if the gallbladder still responded, then we would know that the neurons have no effect on how the gallbladder works. Right?</p>

<p>what was the exact question again?</p>

<p>im pretty sure its motor. then it would be sure that it was not being stimulated. sensory neuron doesnt have anything to do with it. if it still releases bile, its sure that the motor neuron did not influence it</p>

<p>I donā€™t remember the question, but it was something to the effect of does the nervous system stimulate the release of bile from the gallbladder? Now, my reasoning is that the only way this action can be observed is the motor neurons signaling the gallbladder to do its business.
If we cut out the sensory neurons, BOTH sensory and motor neurons would be rendered useless, while the motor neurons is the more direct path. What is it really triggered by, btw? I vaguely recall it being cholecystokinin, right?</p>

<p>can we make a confirmed list of answers o.o?</p>

<p>oā€¦ok i see. I guess i misread the question. great. now im at -3. How much can you miss to get a 750+?</p>

<p>hey what did u guys get for the trees queestion on
E?</p>

<p>can sum1 tell me all the questions for the C+G experiment?
and possibly the answers u guys got</p>

<p>i know one was a picture of each third of a DNA molecule at 72 degrees. i chose A for that one
there were other qs i forgot them :/</p>

<p>the macromolecule structure towards the beginningā€¦ was that a phospholipid? gah i think i put protein (just because i saw a N-C-C) but i didnā€™t have time to change it later.</p>

<p>i put lipid. there was no phospholipid choice was there?</p>

<p>yeah it was a lipid. 750 may be a -6-8</p>

<p>yeah honestly i found the barrons test to be really useless, especially since they did not have any good lab questions, which was what i was particularly weak at. pr and cb were a lot better</p>

<p>Yeah Iā€™m pretty sure there wasnā€™t a phosolipid choice.</p>

<p>"can sum1 tell me all the questions for the C+G experiment?
and possibly the answers u guys got</p>

<p>i know one was a picture of each third of a DNA molecule at 72 degrees. i chose A for that one
there were other qs i forgot them :/"</p>

<p>i put lipid for the macromolecule question
and for the bile question, i remember putting the last choice, something about circulation in the gall bladder because the sensory neurons had to still be there, which would take out the sight,smell,and sensory neuron choices.
for the trees question i put snow because it seemed the most logical? :S
ugh the bald eagle question from the E was exactly the same as a PR practice test and i still got one of the questions wrong about which reason least likely affected the eggs.
the C+G experiment i put 3bondsvs.2bonds for one and for the DNA strand did you guys get like twisted at bottom and top and a gap in the middle?</p>

<p>i remember for one c+g question was like wat distance u think the species were from the hot spring?</p>

<p>i thought it was hot spring-species3-species2-species1 but im not sure
i chose A for the pictures too</p>

<p>but there was an N-C-C, as well as a phosphate attached to itā€¦so I put nucleic acid. I jumped to lipid at first, but then looked carefully at it.</p>

<p>ā€œhe C+G experiment i put 3bondsvs.2bonds for one and for the DNA strand did you guys get like twisted at bottom and top and a gap in the middle?ā€
yes i got the same answers. But wasnt there another q as well?</p>

<p>Uh. There was something about why it was better at higher temps or something?
I put that it was because of the 3 hydrogen bonds between C +G</p>

<p>Andā€¦there was another one that aked for the distance in relation to the hot springs
I putā€¦the one with hotsprings-species 3- species 2- and species 1. I think.</p>

<p>i think i got that as well</p>
