<p>I put random mating for the trait randomly disappearing … would explain it but probably isn’t the right answer. Gallbladder question is 100% MOTOR not sensory!</p>
<p>I found the test fairly easy tbh…was satisfied with my result. May have to retake but overall was ok!</p>
<p>Does anyone remember the rat question quite correctly</p>
<p>I was completely stumped on one of the questions in which there were two species of (clams/mussels ???- I have no idea…) located right next to eachother. The first question they asked about this diagram was what is the separation of this species dependent on?
I believe the answer choices looked something like this:
5)</p>
<p>i completely forgot the last 3 options… one was about eating? 0-0;;
If you guys remember the answer to this, please respond? I personally omitted this one.</p>
<p>After the first 8 questions, I knew forsure that Collegeboard screwed us over for the November test.</p>
<p>oh and also i think i messed these ones up but</p>
<p>a new trait appears within a population- gene flow</p>
<p>a trait moves to another population- genetic drift?</p>
<p>Does anyone know the answer to that question that was like, ‘Which of these choices show evolution?’ The answers had something about a plant grew broad leaves after being moved from sun to shade, and increased antibacterial resistance in a strain of bacteria. It was in the E section.</p>
<p>Hey there!!!
well if it talk about ‘a’ plant then the answer will definitely be the bacteria since evolution cant take place in a single individual.</p>
<p>Of course, I don’t know what I was thinking. Thanks for answering, sadman51!</p>
<p>For the AaBb question about recombonation, were they all possible?</p>
<p>hi there!! i think it would be density bcs did you notice the diagram? the colony had different habibtat but i may be completely wrong.</p>
<p>About the recombination one…yep i think its all of them …it was D i think!</p>
<p>I took the ecology test…I found it pretty difficult overall</p>
<p>Here are some questions that I remember and hopefully we can work out the answers</p>
<ol>
<li>It asked something about cochroaches…why the cochroaches of today haven’t evolved a lot from cochroaches of the past. I picked the answer that said something like “Cochroaches are highly successful so they don’t need to evolve”</li>
<li>The first set of questions about biomes…I believe it was number 2. It said something about leaves that are needles. I thought about cactuses so I put down desert as my answer. Did you guys do the same?</li>
<li>The difference between marsupial and placental mammals? I researched into this and found out that it has something to do with the birth of mature young…not sure what the answer choices were or what I put down</li>
<li>The question about the plants going toward the window…I’m 90% sure the answer is that the side of the plant not close to the window is elongated (auxin works this way)</li>
</ol>
<p>I believe the answer to the question regarding the diagram of the two clams/mussels directly next to eachother read something like , “difference in substrate.” The two clam species were equal distances from high tide and low tide but they resided in different types of soil. I think one was in sand and one was in mud.</p>
<p>A new trait that appears within a population is not gene flow. I am 100% sure it is mutation. (confirmed by Princeton Review)</p>
<p>Another question I remember specifically on the ecology test had something to do with hot springs…there were several graphs involved in this problem. One of the questions asked for the distance of the hot spring relative to the location of something (can’t remember). But the options for the question read something like “Hot spring - 1 - 2 -3” “Hot spring - 1 - 3- 2-” “Hot spring - 3 -2 -1” I had no idea what it was asking for…what did you guys put as your answer?</p>
<p>according to wikipedia, </p>
<p>"Genetic drift or allelic drift is the change in the frequency of a gene variant (allele) in a population due to random sampling.</p>
<p>The alleles in the offspring are a sample of those in the parents, and chance has a role in determining whether a given individual survives and reproduces.</p>
<p>Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation."</p>
<p>… that last sentence makes me almost certain that the last one in that section was genetic drift. got the motor neuron thing wrong though D:</p>
<p>For the clams i put substrate. For the cockroaches i put highly successful body plan. For the hot springs i puy hotsprig-3-2-1</p>
<p>HI!!!
well the def from wiki dosn’t seem to support the idea suddenly does it?
Anyways lets hope for the best result :D</p>
<p>I’m also pretty confident that the answer was genetic drift :)</p>
<p>And yay Happy2102 we put the same answers!</p>
<p>
</p>
<p>Needles … that screams coniferous forest to me. The “needles” on cacti are “spines.”</p>
<p>
</p>
<p>Correct.</p>
<p>
</p>
<p>Marsupials gestate immature young that need further development (in pouches). So it sounds as if you chose the correct answer.</p>
<p>:( unfortunately i missed biological magnification and glycogen is stored in liver, so thats two right off the bat</p>
