November 2010 - Biology (E/M)

<p>what about the one with the hole in the nucleus. i forget what it is called. i put something about how rna needs to get out i think? idk</p>

<p>Wiki says that…
Evidence that mitochondria and plastids arose from bacteria is as follows
They are surrounded by two or more membranes, and the innermost of these shows differences in composition from the other membranes of the cell. The composition is like that of a prokaryotic cell membrane.</p>

<p>Can someone please answer my question???</p>

<p>What do you guys think the curve will be???</p>

<p>IDK math nerd!!!<br>
78 for an 800?
65 for a 700?</p>

<p>the curve will probably remain the same ish. </p>

<p>[SparkNotes:</a> SAT Subject Test: Biology: Scoring the SAT II Biology](<a href=“SparkNotes: Today's Most Popular Study Guides”>SparkNotes: Today's Most Popular Study Guides)</p>

<p>@nwgolfer- that was about pores in the nucleus, and the rna answer was correct.</p>

<p>ok good. </p>

<p>It’s been real everyone. I will be interested to know how we all do when they come out, so make sure you post! unless it is bad. btw, if you don’t hear from me, assume i got an 800 ;)</p>

<p>i hope nritya gets all 80 q’s so i can get a really good idea of my score, eh keep postin lol</p>

<p>haha yeah guys, if you remember any post them so i can complete the questions!</p>

<p>here’s the final draft of them</p>

<li>Elephants and giraffes and such live in the savannah</li>
<li>the sum of all an organisms interactions within a community refer to its “niche” </li>
<li>biomass decreases as it goes up the food chain because the energy is consumed</li>
<li>roots grow downward: gravitropism aka geotropism</li>
<li>plants leaning towards light –phototropism</li>
<li>bacteria moving toward food = taxis</li>
<li>Why shouldn’t you put any nutrients in a group of three plots for the experiment? to have a comparison group (control)</li>

<li>Kingdom contains all the other categories like class, genus, order </li>
<li>Autonomic system controls heartbeat</li>

<li>Something about energy releasing reactions – I and III. (Anyone remember the actual choices?)</li>
<li>eukaryotes v. prokaryotes – lack defined nucleus</li>
</ol>

<p>To the person who said polyploidy, that would be impossible because only plants have polyploidy. atleast thats what i was taught.</p>

<p>humans can be polyploidy too. i.e. 3 chromosomes of 21 in humans</p>

<p>Wait for Mitochondria and Bacteria being similar, I know it was because RNA was similar but I chose something with like different genetic material for like reproducing I think.</p>

<p>Did it say word for word that “it had same RNA,” or along the lines of genetic material?
And for the Egg Shell Thickness what were the questions again?</p>

<p>I said that it decreased the thickness by 0.2 For the 2nd graph.
And I think I chose choice E for the question after that (which was pertaining to the Shell thickness.)</p>

<p>Good job Nyrtia for putting it all together!!!</p>

<p>there was a picture with a backbone structure of a certain cell. </p>

<p>was it a protein because it had a carboxyl group? i remember putting protein</p>

<p>@E=MC: 3 chromosomes of 21 is not polyploidy. Polyploidy is 3n, 4n or n. The only example I remember of polyploidy in animal is part of body of bee is polyploidy, so that it can work better. Of course, it’s just a theory.
Compare to nritya’s list: I got 2-3 wrongs right now :(. Hope that’s still an 800 :D</p>

<p>wait why does the branch remain at 1.5?
trees don’t grow from the trunk?</p>

<p>and can someone mark on the list which were 1-60 and which were M?</p>

<p>oh yes, must have been thinking about something else.</p>

<p>@shortyboiz</p>

<p>i honestly can’t remember whether i saw something similar in a practice test or whether what you’re talking about was actually on the test… but i vaguely remember seeing an amino acid chain (obvious because of the r groups) and must have something along the lines of proteins as the answer. again, this might just be an old memory from a practice exam.</p>

<p>EDIT: i’m agreeing with you… you’re right, its proteins ^^</p>

<p>and i don’t remember which were M and which weren’t. most (almost all, actually) of us took molecular so we didn’t bother dividing the questions up. surely you can tell just by whether the question is familiar or not? sorry.</p>

<p>@nritya </p>

<p>yea that was the question, it had a r- group also so it was definitely a protein</p>

<p>what was the answer to the question that asked for the affect of an increasing pop?Are there new niches developed.The second question asked how bacteria know to go toward food,insight,reasoning,etc.</p>
