June 2012 SAT II Biology

<p>Yeah, there was another one that started w/ 4, the starfish… starfish, whale, duck, shark? I really don’t remember anymore.
And yay! If we’ve gone through all the hard ones, then I have an 800 :D</p>

<p>Edit: Oh wait I just realized that you guys have been going over M answers, whereas not as many people took E. Darn I hope I didn’t miss any on E ><;</p>

<p>i dont remember which one i chose but starfish, whale, duck, shark is very out of logic.</p>

<p>i dont know :(</p>

<p>Aquawater98 i also take E section.</p>

<p>Do you remember something from E section></p>

<p>Well it would make sense for people that forgot mammals came last :P</p>

<p>Hmm let’s see for E. I’ll try to compile a list here. Add on if you remember anymore.</p>

<ol>
<li>Aorta = pumps blood throughout body</li>
<li>Right ventricle = sends blood to lungs</li>
<li>Arithmetic diff b/n energy produced by producers and energy taken up by producers + consumers = net community production </li>
<li>Very first column was answer to a question… I think the one w/ the most net primary production (it asked what had the most energy after accounting for respiration I believe)</li>
<li>Energy produced unhindered by cellular resp = gross primary production</li>
<li>Two areas w/ no net community production = the ones w/ 0 on the bottom row, or the two columns that were on the right. </li>
<li>Some question that had to do w/ the 4 above. </li>
<li>Bacteria chart after 48 hrs - 50,000
Remember the other 3 questions for bacteria? </li>
</ol>

<p>Aghh I have a bad memory :confused: was the rat litter one on E or general?
Ok I actually don’t know what net community production is forsure, and Google isn’t helping. Anyone here know?</p>

<p>i actually remember that i chose net community production very very often :(</p>

<p>others were easy.Think about those questions.They were hard :)))</p>

<p>Others were easy… others as in the ones that I posted not about net community production or the ones that I forgot?</p>

<p>that you mentioned.for example heart question was very easy.</p>

<p>yes net community production was hard …imho</p>

<p>for the enzyme denaturation question, wouldnt it be freezing instead of temperatures above 100 F? since most enzymes work at body temperature which is about 97 ish, but definatley not 0-?</p>

<p>Freezing wouldn’t denature an enzyme though. It would just work a lot slower. The only time an enzyme would stop moving completely during freezing is if it reaches absolute zero, which can’t happen yet.</p>

<p>Is sparknotes’ score conversion table accurate?
[SparkNotes:</a> SAT Subject Test: Biology: Scoring the SAT II Biology](<a href=“SparkNotes: Today's Most Popular Study Guides”>SparkNotes: Today's Most Popular Study Guides)</p>

<p>^^^ Enzymes work at around 97 degrees Fahrenheit. The question said 100 degrees Celsius, which is 212 degrees Fahrenheit. It also specified “permanent” denaturation, which could only be achieved by boiling (out of the answer choices).</p>

<p>For the vine graph which one is it. Slightly steeper or really steep?</p>

<p>Also for the plant graph was it plants only carry respiration at night or there’s a high O2 productiom during te day than what is used for respiration</p>

<p>Guys what are your score predictions so far? It seems we are pretty happy with how we did :)</p>

<p>Can someone post list of all questions for E if you remember.Looks like only 7 or 8 got posted so far.</p>

<p>Molecular compiled list

  1. starch stores energy in plants
  2. changing blood type or whatever would not affect hemoglobin shape
  3. Restriction enzymes work by something about complementary DNA
  4. companion cells
  5. Glycogen is a short-term energy storage molecule
  6. Dehydration reactions
  7. H20 is another product of making a polymer
  8. the hydrogen atoms at the end would be removed
  9. the order question was letter E…I dont remember the roman numerals
  10. using a molecule that is more effective in highlighting DNA was the one where DNA was bolded and the spindle was a dashed line
  11. i believe there was another question in the mitosis lab where the answer was anaphase
  12. Cell was from a plant
  13. 400-450nM
  14. Violet
  15. 02
  16. Nervous system responds first
    Anyone remember the last 4?</p>

<p>tenisgirl3232 plant respirates every time.eliminate it</p>

<p>What did you all get for the question with the aquatic plants and which were most likely? I’m not sure what the question was, but I put that there wouldn’t be many oxygen-seeking bacteria around. There was also an option with acidity and chlorophyll. What do you think?</p>

<p>Acidity was wrong because it said substantially (and the PH would actually drop a bit, not much) and the chlorophyll was wrong also so bacteria was correct</p>

<p>Why was chlorophyll wrong? Can you explain further? thanks</p>
