January 2013 Biology E/M SAT Subject Test

<p>@nycguyy: would you mind explaining your answer</p>

<p>It seemed to be the best choice. I just looked it up and this is what newsmedical.net has to say:
‘Cartilage is composed of specialized cells called chondrocytes that produce a large amount of extracellular matrix composed of collagen fibers, abundant ground substance rich in proteoglycan, and elastin fibers.’</p>

<p>OK you’re right</p>

<p>come on people, more questions</p>

<p>anyone remember the reason for tissue formation due to chemicals when cells close together?
what about bacterial genetic recombination. i put all (conjugation, transduction, transformation)
galactosidase…
evolved because lactose not always needed
one mutant will express it no matter the lactose
inhibit RNA before adding lactose</p>

<p>Don’t remember tissue formation
I put all for bacterial recombination
Galacosidase: same answers</p>

<p>ok so I compiled a list of the ones I’m pretty sure I’ve figured out</p>

<p>reptile salamander<br>
bilateral symmetry- jellyfish
8 genes code for 8 proteins
blood type- AB
plasmodesmata
transpiration pull
random mating
dihybrid cross
350 or 325 (intron/exons q, don’t remember the numbers)
increased resistance against a disease
frog/tadpole water vs land<br>
cartilage connective tissue<br>
grasshopper legs was b
photosynthesis rate was slope
directly proportional
chordata- was not notachord or w/e that’s all I know<br>
platelets clot
erythrocytes carry oxygen
19. 36 atoms involved in reaction<br>
20. erythrocytes lacks nuclei
21. excretory was a in grasshopper<br>
22. cells made in bone marrow<br>
23. gel electrophoresis
24. starch/glucose bag swells
25.rainforest has greatest diversity
26. humans and chimpanzees evolutionary relationship means common ancestor
liver is an organ
adaptive radiation
convergent evolution
the one with the base and percentages- 20%</p>

<p>ignore the numbers! please add to list!</p>

<p>anyone remember the question about intermediate width and which species would prefer it</p>

<p>We have disagreement on cartilage, hough extracellular matrix/proteins seemed correct.</p>

<p>oh I mean I compiled the list from the threads from the last time this same test was distributed I actually put something different altogether… your answer was also argued so it may be the answer.</p>

<p>@RickyRoma Intermediate width was the red would occupy higher elevation and black would occupy lower</p>

<p>also I’m not sure why it’s competitive displacement…the two colored birds occupied different niches didn’t they? I put mutalism though that’s obviously not correct…they didn’t benefit from one another</p>

<p>This test was recycled? Do you have the link from the thread you mentioned.
I put competitive displacement because they are the same species but left due to competition, and the other choices weren’t as good.</p>

<p>Yeah, I agree with you. Wish I’d put that. My internet is acting up but part of it was October 2008 and also January 2010. There may be more!</p>

<p>Intermediate altitude: I put more blacks than reds based on some inference (more blacks prefer low than reds prefer high). What did you guys get?</p>

<p>@katzly you are so right! I looked at the October 2008 test and there is so many similar questions. I can’t believe they would do that. Is it normal for them to do that?</p>

<p>Where are you getting these old tests?</p>

<p>read the comments on the October 2008 test</p>

<p>They recycle every single subject test they put out ever, for the most part! I’m pretty sure ours had a few new questions though. Guess we’re special :)</p>

<p>College Board recycles most if not all SAT subject tests, that’s why it releases only one official practice test.
I actually checked the January 2010 thred but most information are conflicting and pretty useless. BUT cartilage was mentioned so I regret not studying it.</p>

<p>So was the answer to the cartilage one with the “connective tissue in it?”</p>
