<p>What'd you guys think ?</p>
<p>how does 3 wrong and 1 skip look for bio m</p>
<p>@lalala, that’s a little below 800 I think, probably around 780.</p>
<p>I have so many questions but I don’t think I’m allowed to post yet.</p>
<p>wait why arent we allowed to post yet?</p>
<p>Because people are still taking the test, and they could look up answers.</p>
<p>Test wasn’t too bad. I’m really glad I chose M, because those were the easiest 20 questions IMO.</p>
<p>I think the beginning and the end of the base section were hard (Islands problem and land colonizing organisms).</p>
<p>I tried doing the m section and it was hard, so i switched over to ecology and it was a breeze</p>
<p>when can we start talking about the answers</p>
<p>wow I think I got a ton of stuff wrong, this test was pretty hard…hoping to see if someone remembers all 100 questions and the answers to them HAHA, it’ll convince me if I should cancel and take the june or not…so someone should do it quickly :)</p>
<p>Those island questions were hard for me
I don’t know how size or distance from mainland could affect extinction</p>
<p>The theory of island biogeography proposes that the number of species found on an undisturbed island is determined by immigration and extinction. And further, that the isolated populations may follow different evolutionary routes, as shown by Darwin’s observation of finches in the Galapagos Islands. Immigration and emigration are affected by the distance of an island from a source of colonists (distance effect). Usually this source is the mainland, but it can also be other islands. Islands that are more isolated are less likely to receive immigrants than islands that are less isolated.</p>
<p>The rate of extinction once a species manages to colonize an island is affected by island size (area effect or the species-area curve). Larger islands contain larger habitat areas and opportunities for more different varieties of habitat. Larger habitat size reduces the probability of extinction due to chance events. Habitat heterogeneity increases the number of species that will be successful after immigration.</p>
<p>Over time, the countervailing forces of extinction and immigration result in an equilibrium level of species richness.</p>
<p>was RNA polymerase one of the answers. and for the water and substance separation was it lipids?!</p>
<p>water separation was lipids. i don’t remember RNA polymerase as an ans sorry. Do u rem the question?</p>
<p>i agree with $money</p>
<p>So island A had the most diversity. C had the least immigration. Where was the lowest extinction rate? And what was the last question for that?</p>
<p>I put C for lowest extinction rate. It was a guess but I thought there would be the least species, thus the ones that do make it all the way must be pretty well adapted. But really idk. Anyone pretty sure/ have evidence?</p>
<p>anyone remember what the one with the picture of the jellyfish, starfish and i think worm was?? i was confused on tht one</p>
<p>it was the one with the radioactive isotopes and the endoplasmic reticulum. It said which of the following probs had the amino acid radioactive isotopes or some jazz like that…near the end of el test</p>
<p>What about that question about the tree and the scar the branch left? I Had no idea how to do that…</p>
<p>there was a worm a jellyfish and a hydra and I forgot the last one but it wasn’t relevant…it was jellyfish and hydra I believe</p>
