<p>no more discussions here? :[</p>
<p>what's the fused chromosome question all about... I was blank for that one....</p>
<p>Wasn't there a question about sodium into a cell? Was that facilitated or simple?</p>
<p>i think the fused chromosomes one looked had a couple chromosomes in anaphase but one pair looked like this >< and couldn't seperate maybe?</p>
<p>I'm pretty sure that the fossil order one is shark, starfish, dinosaur, bird- starfish is an echinoderm which is closely related to chordates.
Also for the closest related to the primate one isn't it whale (because they both are mammals). A lot of people are saying that it is dinosaurs and unless i read the question wrong, that answer is completely wrong</p>
<p>The fused chromosome question was E. This is because it said that they fused at the ends, and in that one, two ends of sister chromatids were stuck together. In mitosis (and i think meiosis), the spindle fibers attach to the center of the chromatids and pull them from the middle, so if two were together, then it would be like this <_> (except that in the picture the connection was on the top).</p>
<p>Also, for the question with "if it had stained the DNA more than the proteins" or something, it was the one with the chromatids as more bold, and the spindle fibers less bold right?</p>
<p>does M generally have an easier curve than E?</p>
<ul>
<li>i did E.. it's easier. but i think the curves are around the same.</li>
<li>t-rex is definitely not a mammal... whale is most closely related to primate (both mammals) i think.</li>
<li>order of evolution was starfish, shark, t-rex, duck.. i think. sharks are chordates..</li>
<li>genetic uniformity of cheetahs -> bottleneck effect? not sure</li>
<li>leeches aren't arthropods.. they're annelids</li>
</ul>
<p>yes i put bottleneck for cheetah question.</p>
<p>for the phloem one, wikipedia says
"Phloem tissue consists of less specialized and nucleate parenchyma cells, sieve-tube cells, and companion cells (in addition albuminous cells, fibers and sclereids)....The survival of sieve-tube members depends on a close association with the companion cells. All of the cellular functions of a sieve-tube element are carried out by the (much smaller) companion cell, a typical plant cell, except the companion cell usually has a larger number of ribosomes and mitochondria."</p>
<p>so i think the answer's companion cells.. ?</p>
<p>YES! I said companion cells.
I got the closest to primates wrong I guess, I said whale, I didn't know dinosaurs were mammals???
It was 2/3 for uric acid 99% positive.
What was the Darwin natural selection, I was wavering between DNA and Populations and went with populations bc of the wording, I guess.
I said starfish, shark, t-rex, duck, even though it angered me.
The one with the chromosone malfunction??? I had NO IDEA, the picture was so ridiculous that i wanted to die. I said A. I guess I got that wrong too.
There were a bunch of other iffy ones, so I might cancel.
I guess I got leeches right.</p>
<p>THE DIAGRAMS SUCKED!!!!!!!!</p>
<p>And the eye question? What the heck? I thought this was general biology! We didn't even go that indepth in AP!</p>
<p>I thought the Molecular section was pretty easy...although I wasn't sure about the plasmid question...I think I picked whatever A was, or maybe left it blank. I was decently sure about everything except the eye stuff and the hideous plant drawing...I know that the 2nd out of 3rd question about the plant diagram was supposed to be a xylem, but I didn't know which it was...I picked the one corresponding with the blank spot in the middle of the diagram.</p>
<p>^I took psych so I'm pretty sure I got at least 2/3 right, I'm just not sure about the one that focused, I said it was the pupil but now realize its the iris which was also the answer to another one. So blah. Oh, and the plant diagram WAS hideous, beyond all comprehension. I said xylem was that bizarre ring thing just stuck in the middle of the diagram.</p>
<p>im pretty sure dinosaurs are reptiles.. i put whale for that.</p>
<p>bird and t-rex for uric acid</p>
<p>populations for natural selection</p>
<p>i put starfish, shark, t-rex, duck, but im not sure..</p>
<p>i think the chromosome one was the one with /_____\ but upsidedown from that.</p>
<p>does anyone know the answer to the question that was like which biome has the greatest diversity?</p>
<p>^^Oh, I had no idea for the biome, I said coral reef, but it was probably the forest one. I really wish they had included rainforest, then it would have been easy.</p>
<p>Ugh, now I remember that terrible chromosome thing from class, I just had memory blahh moment. So I have confirmed at least 3 wrong so far, what about you guys?</p>
<p>it is coral reeef Coral</a> reef - Wikipedia, the free encyclopedia</p>
<p>Yes!!! Thanks!</p>
<p>For the M section, the picture of the molecule was an amino acid, right? And the bond would be at 5, and it produces H20, right??</p>
<p>for the evolution one w/ the five diff animals, look at this diagram
<a href="http://www.dhushara.com/book/evol/trevol.jpg%5B/url%5D">http://www.dhushara.com/book/evol/trevol.jpg</a></p>
<p>yes yes and yes to the amino acid stuff</p>
