May SAT II Biology E/M

<p>So what was the ear question!?!?!?</p>

<p>DDT I said it accumulates on higher levels of food chain.</p>

<p>for the DDT one, pretty sure its accumulation in higher trophic levels.</p>

<p>why is it enzyme hydrolyzes instead of low temperature=low reaction rate?</p>

<p>^is that question molecular? I didn’t get any enzymes.</p>

<p>^is that question molecular? I didn’t get any enzymes. </p>

<p>^ It was molecular.</p>

<p>I put low temp = lower reaction rate. :/</p>

<p>oh thank god. i didnt get that question either. i though i was going crazy.</p>

<p>For the lab with the 4 quadrants, what were the answers?</p>

<ol>
<li> the tetracy-whatever…ine</li>
<li> they are penicillin resistant (E)</li>
<li> Also E I think, agar with bacteria but no antibiotics?</li>
</ol>

<p>anyone know the curve the test?
my kaplan book is saying 77 is the minimum for 800.</p>

<p>got that mitotic division wrong… can’t believe i made such a stupid mistake… I put down differentiation LAWL (because i thought the bottom one was going to be the root since it looked different… faill
1 confirmed error so far… hopefully nothing more.</p>

<p>btw, that one was low reaction rate, i’m sure of it.</p>

<p>As for the ear, [Basilar</a> membrane - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Basilar_membrane]Basilar”>Basilar membrane - Wikipedia)</p>

<p>answer both E and M, E was a lot easier and pretty much consisted of reading graphs and common sense. choose M at the end.</p>

<p>They don’t dock points if you bubble both sections right? cuz My friend did that last year and still got 800… hopefully they don’t change that policy.</p>

<p>Based on the only test CB released, it is
For E, it is
800
800
800
790
790
780
780</p>

<p>I remember 10 wrong (-12) being 740.</p>

<p>For molecular, it is one more 800, then the same.</p>

<p>I felt that that test was easier than this one. Hopefully the curve for this is one more 800 :D</p>

<p>What letter was the ear question? I put D.</p>

<p>^
I did that too. @_@</p>

<p>@ RAlec, I got “the same agar in the dark”, E foe the last bacteria lab question as well.</p>

<p>what was the answer for the one where some sort of seed is crushed and the resulting liquid is placed in water, but the liquid separates from the water and falls to the bottom of the container? the question asked what type of macromolecule the liquid had to be.
answer choices were: enzymes, proteins, lipids (thats what i put), hydrocarbons, and nucleic acids.</p>

<p>It was lipids.</p>

<p>Can someone explain the enzyme question in more detail? I don’t really remember it.</p>

<p>it is lipid</p>

<p>wait, the same agar in the dark? I don’t remember putting that. that would test light and dark, where a control would be agar with bacteria, but no antibiotics.</p>

<p>wait, the same agar in the dark? I don’t remember putting that. that would test light and dark, where a control would be agar with bacteria, but no antibiotics.</p>

<p>^
I said bacteria on same plate with no antibiotics.</p>

<p>yay! thanks!
and for the enzyme one, when the temperature is lower substrates move around slowly which decreases the chances of a substrate coming into contact with an enzyme.</p>

<p>^ I would imagine that I put that too, because it was what I was trying to look for. great.</p>

<p>What was teh answer to the muscle contraction? It needs ATP? or ADP?</p>
