May SAT II Biology E/M

<p>i feel like there were more i was unsure of. i dont remember them tho . ugh. this sucks. i have such a bad feeling about all the subject tests</p>

<p>no, concentration decreases, because water flows in due to osmosis</p>

<p>really? <em>crossing fingers</em>…anyone confirm?</p>

<p>can someone give me a link for the average curve for bio M? i only signed up for math 2 and ush for today but i was in the test mood and decided to take it (considering i finished college bio this semester) didnt think it was too hard but definitely skipped like 3.</p>

<p>shooting for those 800 across the boards baby</p>

<p>what did you put for the small circle in a big oval? species/species? or genus/species?</p>

<p>the one with bacteria grown together in a single petri dish or whatever. the equilibrium populations in the end after doubling starting populations. anybody know the answer to this?</p>

<p>species genus and for the concentartion one, it would go down.</p>

<p>species/genus</p>

<p>species genus i think. because the circle is the species.</p>

<p>The small circle was species, the large one was genus.</p>

<p>The concentration one had a graph that was a slight downwards curve I think.</p>

<p>the graph was a slight downward curve that gradually became stable because it will reach equilibrium. can anyone answer my question on top with the bacteria? i answered that the result will be the same equilibrium populations.</p>

<p>Bio M curve: (based on the only Bio M test released by CB, I think today’s test is harder so hopefully better curve?)</p>

<p>800
800
800
800
790
780
780</p>

<p>E is same thing, but one less 800.</p>

<p>the one with bacteria grown together in a single petri dish or whatever. the equilibrium populations in the end after doubling starting populations. anybody know the answer to this?</p>

<p>^YES this is the one I need help with. Just remembered it.</p>

<p>I put A double the equilibrium. I was torn between A and B. I had no idea, and was rushed. What did you all put? (Don’t trust my answer)</p>

<p>Is that for E? Because I took M =)</p>

<p>Yes that question was for E, and i choose the same. (as in same equlibrium point)
Resources are the same, therefore, the population equilibrium is the same.</p>

<p>(this answer actually came from calc BC class… we did differential EQs and there were questions like that LOLLL)</p>

<p>What was the answer to the question about why carrots become flexible? was it because the cell membrane shrinks from the cell wall?</p>

<p>And what were the answers to the last two problems for test M about the enzyme reaction rates?</p>

<p>Yes, its b/c of the cell wall shrinking.</p>

<p>I think it was something about lowering the energy of activation and I don’t remember the last one.</p>

<p>cell wall? or cell membrane?
and i think i got like 2 A’s for the last two…</p>

<p>I meant membrane, lol. The Cell Wall can’t shrink. I don’t really remember the last two, you would have to give me the question so I can solve it a again =)</p>

<p>What was the answer to the ‘which one doesn’t have a membrane surrounding it?’</p>
