/// SAT Subject Test in Biology \\\ 2012, October, 6

<p>It wasn’t exactly proteins. But all the other ones were completely incorrect.</p>

<p>

</p>

<p>What was the original question?</p>

<p>And about the phylogenetic tree question … that was ecological niche.</p>

<p>

</p>

<p>You thought an LH spike is needed for spermatogensis :rolleyes:</p>

<p>It was asking about the bat wing an bird wing and i think it was convergent too. </p>

<p>Also c and d was an answer?</p>

<p>

</p>

<p>I remember a bat and fly wing.</p>

<p>No I didn’t put that I just didn’t know what the answer was lol. All the other ones didn’t ring any bells. It’s been about a year since I’ve taken any form of biology class loolloololol</p>

<p>

</p>

<p>It shows. Anyway, I’m concerned now … is it a bat/bird or a bat/fly? The former is homology/divergent evolution; the latter is analogy/convergent evolution.</p>

<p>IceQube: it was bat and moth, so it was indeed convergent evolution. and ecological niche is what i got for the phylogenetic question too…</p>

<p>Lol this guy! Anyway it is bat fly, so I believe it to be convergent!</p>

<p>

</p>

<p>Correct, because differences in the amino acid sequences of proteins are used in evaluating the levels of similarity among organisms. It’s called molecular homologies. The amino acid sequences of hemoglobin may be used. Cytochrome c is another commonly studied protein.</p>

<p>IceQube: hell yea so it looks right now like 78 right, 2 wrong. is that an 800?</p>

<p>What grade are you two in anyway?</p>

<p>

</p>

<p>No, the clue about “spiny” plants and “nocturnal” animals and daily temperature fluctuations should have led you away from the choice whose main characteristics are coniferous trees and uniformly freezing temperatures.</p>

<p>

</p>

<p>Do I need to change my location data to read “your arms”?</p>

<p>I hope 770 math ii looks good compared to low 600 on this hahaha</p>

<p>alargeblackman: 12th (taking ap bio currently, so selfstudied)
IceQube: hahaha i like your wry sense of humor. ye that question was a gimme lol</p>

<p>

</p>

<p>I’m sure there’s more of me that you love.</p>

<p>Haha I mean it’s great humor but I really fail to see why this guy thinks that knowing multiple choice answers to in fact a third college admissions test means anything about intelligence…I’m just saying.</p>

<p>Was it meiotic divisions that were needed for spermatogenesis? What were the other choices for the biomes question? Hoping that I picked desert. :/</p>

<p>There’s no way that the carrying capacity could’ve been 500 right? The graph spiked to 500 and then leveled to 400 if I remember correctly…</p>

<p>It was 400 bro…</p>

<p>Meiosis. :heavy_check_mark:
K = 400 (K is defined as Karrying Kapacity) :heavy_check_mark:</p>

<p>@ablack: true…
@IceQube: chill bro…
@russgenious: ye meiotic, and the carrying capacity was 400 b/c that’s what is stable (by definition of carrying capacity)</p>
