SAT Subject Test January 2009: Biology E/M

<p>Yeah, it was the starfish, then fish, then dinosaur, then birds.</p>

22

<ol>
<li>what type of signal is used b/w (something about neuromuscular junction) nerve and muscle cell?</li>
</ol>

<p>I put chemical (acetylcholine). I was stuck b/w that and electrical.</p>

<ol>
<li><p>This one was on the M test. The one about different wavelenghs about the aqatic plant thats exposed to the light that had the lowest rate of photosynthesis?</p></li>
<li><p>what contained both RNA and protein?</p></li>
</ol>

23

<p>for the rat question...it was that they were all on the same diet...</p>

24

<p>what was the one about convergent evolution dealing with the pics of the starfish, etc...?</p>

25

<p>Aquatic plants was lowest amount of O2 dependent bacteria.</p>

<p>RNA + Protein was the ribosome.</p>

<p>Convergent evolution was the shark and the whale (I actually had that exact example of convergent evolution in my biology class).</p>

26

<p>anyone know the curves for the bio m? </p>

<p>i hope its not the same as the one in the princeton review books.</p>

27

And coral reef is most diverse.

Lol, that was an answer for a previous test.</p>

<p>I think it was the same question too.</p>

28

<p>for the rat question i put it was that they had to be genetically diverse. because when you think about it, if you have a bunch of, rats or anything from the same family or whatever, it may be somewhat genetic that they give birth at around the same time, or that the offspring have a greater chance of dying if they are kept in the womb longer, etc. but if you have rats from all over the place, the chance that this is the case decreases. is this flawed logic?</p>

<p>i was leaning towards the diet one.</p>

29

<p>i dont think the gestation period has anything to do with being from the same family..its the about the same for all the members of a species...</p>

<p>if they were on different diets then the experiment would be flawed because one diet could decrease/increase the mortality rate of the infants.</p>

30

<p>what was the answer to the chlorophyll prodution graph question asking about 500nm green spectrum light?</p>

<p>Someone already said lower oxygen bacteria. I had that answer first but changed it to less chorophyll, since chlorophyll is green and thought there would just be more accessory pigments.</p>

31

<p>Actually, </p>

<p>Engelmann did this exact experiment and found lower levels of the aerobic bacteria in the green light.</p>

32

<p>this was the EXACT same test as the on may 2008. look at the threads.</p>

34

<p>You're right...that's strange...is the collegeboard getting lazy?</p>

35

<p>I thought that this was fair enough, but I got stumped on the whole eye diagram. Also, what was that global warming question? I put something with acid rain, but I felt that question is debatable because it is not known for a fact if humans are contributing to global warming...?</p>

36

<p>And wow!!! That is realllyyy sloppy effort.</p>

37

<p>The answer to the global warming question was greenhouse gases.</p>

<p>Although you could technically argue that humans do not cause global warming, this is a debatable point (with the majority of the scientific community believing that we do), and we are instructed to pick the BEST answer. The greenhouse gas effect is well-documented and proven. It is fully accepted by science.</p>

<p>The question did kind of make me laugh, though. If you really wanted to, you could probably get away with the human thing and argue with the collegeboard that it's an opinion and not scientific fact (just a widely held theory backed up by a lot of circumstantial/empirical evidence).</p>

38

<p>Haha maybe I will give the CollegeBoard a piece of my mind hahah =).</p>

39

<p>Oh and btw, it asked which did NOT contribute. I though that greenhouse gases were a major cause....</p>

40

<p>Is this test at all similar to the ACT Science section? I got a 33 on that, and after this discussion, I feel I should have taken this instead of the Math Level II today.</p>
