<p>all cells have ribosomes yes</p>
<p>This is why these tests just suck. We should be able to see the right answers later on, but we never get to.</p>
<p>Any consensus on my previous question?</p>
<p>Also, maybe you guys are right about III, I’m thinking of allele frequencies, not viruses. Maybe it’s not the same thing.</p>
<p>For the guys who took Ecology!! Can you please try to remember what II was on the HIV question!!</p>
<p>Um, I don’t remember if this was I or II, but I want to say that one of the options was about the viruse moving from one animal/species to another? Or it might have been something to do with the viruse’s genome</p>
<p>Now that you say that about the different animal species, it sounds familiar but I cannot confirm. Can you remember it greg?</p>
<p>I was mutations! III was moving to bigger populations. And I think II was like moving from a one animal/species to another… but I can’t remember exactly… :(</p>
<p>djumper and supergrover911, what did you guys put for the ray finned and lobe finned fish question??</p>
<p>I put I and II. I originally had all three, but then the last one started to sound strange.</p>
<p>Well I am now certain that II was right. I googled transfer of virus between humans and animals, and it said “mutate”. As long as II was about transfer from human to animal. As for III, I don’t know.</p>
<p>I don’t think we’re going to come to a definite conclusion with the pines.</p>
<p>I and II, no doubt. The third was illogical. One still existing today has to do with its own genetics, not its descendants.</p>
<p>wikipedia says, “Non-tetrapod sarcopterygians (lobe finned fish) continued until towards the end of Paleozoic era, suffering heavy losses during the Permian-Triassic extinction event (251 Ma).” </p>
<p>ughhhh, but when I think about it, it really doesn’t matter because their extinction or decline in numbers doesn’t point to their evolving into tetrapods!</p>
<p>And the pines one was very tricky!! how are we supposed to know that pines grow better in drained soil?!?!?</p>
<p>What is the curve for the Biology M test</p>
<p>Moreover, one group of lobe-fins gave rise to the tetrapods, which have become other most successful group of vertebrates. Strictly speaking, since tetrapods evolved from lobe-fins, all tetrapods –including us— are also lobe-fins.</p>

<p>okay it’s I and II only!!</p>
<p>do you think next months sat is going to be easier?</p>
<p>So if I only missed the pine and HIV ones, what am I looking at with none omitted? 790?</p>
<p>ughh… 
i got the cambium one wrong!! the lobe fished one wrong!! HIV an pine still in debate… ■■■</p>
<p>Where did everyone go? I thought of some more questions from core, but want to confirm the ribosome one first. It’s the one that prokaryotes and eukaryotes both have, correct?</p>
<p>^yes, it’s correct!</p>
<p>Most evolutionary success- Arthropoda?</p>
<p>^yep!!!</p>
