January 2013 Biology E/M SAT Subject Test

<p>Energy cannot be created or destroyed, so the atoms being used are 6 carbons, 18 oxygen and 12 hydrogen. That is 6+18+12 = 36</p>

<p>ok thanks to the guys who responded to my questions.</p>

<p>Another thing, does anyone remember the wording of the question were the answer was cartilage/connective tissue because I can’t remember what exactly I put for it. </p>

<p>@ RickyRoma</p>

<p>In your post (#53 on this thread) where you put down your answers for everything you remembered, do you remember what the question for #3 (which you said Natural Selection) was? And for “Inhibit RNA before adding lactose,” what was the wording of the question for that one? If you remember, of course :slight_smile: it’s just that I don’t remember what those two questions asked specifically.</p>

<p>^lol, wrote “remember” a little too often in that last post.</p>

<p>Oh and yeah, it’s 36 for the atoms, can’t believe I put 72. Silly mistake, same with the Blood types (I put O negative when it’s clearly AB)</p>

<p>So generally, was the Molecular test easy for you guys?</p>

<p>I’m trying to gather a general consensus to see whether the curve would be good enough that I wouldn’t have to cancel my score.</p>

<p>There are Y-linked traits. They exist. [Y</a> linkage - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Y_linkage]Y”>Y linkage - Wikipedia)</p>

<p>This results in the passage of all information from fathers to sons.</p>

<p>Hey, does anyone remember that one question with the evolution lineage branching thing (this may have been in the ecology section)? It had like lobster and shrimp and stuff branching out.</p>

<p>Also, if you took ecology, one of the last questions had a graph of nitrogen levels and two animals, and wanted you to define the relationship between the two animals. I put that they competed with one another, but I’m pretty sure that’s wrong, since both of their lines sloped down at the end.</p>

<p>For the lineage thing I think I put when the water flea branched off from the shrimp on the far right… And then the nitrogen graph was that one line (not algae or other thing) was eating the algae (as algae decreased, nitrogen increased which shows the predator was not using nitrogen but feeding off the algae). As the algae depleted, the predator died because of lack of food.</p>

<p>Was the water flea on the far left, next to the lobster or something?</p>

<p>what was the lineage thing? like do you remember the exact question? I also remember saying that the water flea was just as related to the lobster than the one where it branched off the lobster. i got the eating algae thing. did you put larger algae productions led to decreased amounts of nitrogen</p>

<p>Also does anyone remember the question about lungs? I remember putting pneumonia, but I wasn’t sure it was tuberculosis.</p>

<p>it was enphesyma.</p>

<p>was that question in the ecology section?</p>

<p>The one about the flea and lobsters—yes. the other one about smoking, no.</p>

<p>It did say Y chromosome (It’s a rare occurrence, but I’ve read about it in the Princeton Review or something).</p>

<p>The emphysema answer is correct. All the other were infections (pneumonia, tuberculosis, etc.) that aren’t necessarily caused by smoking</p>

<p>Did you guys put that placing the seeds in a cold temperature for an extended period of time would increase germination?</p>

<p>And emphysema is correct… I got that one wrong though. How in the world do they expect us to know that ;____;</p>

<p>Also, can anyone give some additional info on the DNA sequence problems at the beginning? I was really confused about them for some reason…was it asking for the sequence of the complementary strand, or the same one? I assumed it was the same one, and wasn’t sure about the inversion mutation and the point mutation ones.</p>
