January 2013 Biology E/M SAT Subject Test

<p>Discussion and results.</p>

<p>Good luck everyone!</p>

<p>Hey. I just finished the Biology SAT E. Not expecting an amazing score, as I studied for about 4 days this past week, and other than that, this is the first time I’ve looked at Biology since 9th grade. This was my third and final subject test though, so I’m happy to be done!</p>

<p>Hijacking the thread a bit, I made a pretty dumb error by bubbling in my answers on the back of the test booklet where I would, if I was taking a third test in the same day. I left the other two middle test grids blank. Does anyone think this will be a problem for the collegeboard when scanning/grading my test?</p>

<p>i just took it too.
That shouldnt be a problem, your scores might be delayed though, I think you should call college board and notify them.</p>

<p>I just took it as well. What did you put for the labeling of the grasshoppers’ body parts? And why do humans only eat the leaf part of the plant (I put that it has less cellulose and more nutrition than the woody part).</p>

<p>Damn, got 3 wrong. Any chance of an 800 assuming I do no worse?</p>

<p>@candicat: I put the same for the plant question. And for the insect one, I believe that they were all A.</p>

<p>guys lets discuss specific questions, does anybody know the answer for the dna strands one? Also the graphs. I’m pretty sure the insect one was B-A-A</p>

<p>does anybody remeber the answers to the hemoglobin graph?</p>

<p>Ones im not sure about:
what is true about most human genes? I put code for structural proteins
I put B for where legs are adjoined, A for reproductive structures and excretion
leaves have less cellulose and are more nutritive than wood</p>

<p>I put at low pressure, infant’s hemoglobin binds to oxygen better</p>

<p>I didn’t put the structural proteins because aren’t most proteins functional proteins? I think I put something about being unique but I wasn’t entirely confident with that so take this with a grain of salt.</p>

<p>@RickyRoma
For most human genes, I put “common to/share with other animals”
(I’m not sure the question asks for proteins)
Leaves have less cellulose and more nutrition</p>

<p>I agree with disguy
did anyone put they would not chose the intermediate width
cartilage is epithelial covering?</p>

<p>problem with adenine synthesis for red bacteria?
i also put UV would cause mutations and effect DNA</p>

<p>UV causes DNA mutation
isn’t cartilage fiber with no nucleus or something like that
Intermediate width: less red and more black?</p>

<p>I got cartilage wrong - it was the connective tissue choice
why less red and more black?
I also put competitive displacement and the group would not help with reducing disease</p>

<p>Tadpoles ammonia frogs urea because tadpoles live in water and frogs on land?</p>

<p>I’m not sure about the cartilage one.Wikipedia says it is a collagen fiber, so… Don’t remember the exact answer choices</p>

<p>anyone remember the light versus blue dye experiment</p>

<p>i put slope for first one
i put directly related
i put last 30 seconds not as much as first 30 seconds
i put control for how it would be if there was no light</p>

<p>I put that cartilage is a extracellular matrix with proteins</p>
