December 2010-SAT II Biology E/M

<p>^IT was just RNA and protein. Not mRNA and protein.</p>

<p>Yeah the ribosome was 5. I used as an answer twice.</p>

<p>oh yes i remember the insects and decomposing tree one. I put the answer that was like the carrying capacity graph where is starts off exponential growth then levels off at the point and stays there.</p>

<p>Wasn’t sure if i put the right one cuz there was another graph that was bell-shaped. Do the insects leave the log after they decompose it or do they continue to live there?</p>

<p>For the insect one i put the line that had a slope of -1 about. Since the tree was decomposing, wouldn’t the insect population be dwindling? </p>

<p>The human growth one was exponential.</p>

<p>Deer population was the line that leveled off (carrying capacity)</p>

<p>well didnt it say the tree died so it started to decompose? Wouldnt the insects need to grow on it to decompose it</p>

<p>Thats exactly what i put</p>

<p>^no it said the tree died after decomposing. So all the insects there died as well. It was the one with the slope of -1. I read that question over like three times.</p>

<p>omg good i put the thing with the slope -1 whewwww cause i was like if tree dies, insects die too…</p>

<p>The bell curve showed the insects dieing too. I assumed that the insects helped decompose the tree and their population would increase due to the food source. Then it would decrease as that food source ran out.</p>

<p>Both #1 and #2 were mitochondria right? I hate it when answers are the same</p>

<p>ah crap haha i dont know… but wouldn’t the original food source the tree provided for the insects be greateest in the beginning?</p>

<p>@wang yeahh haha :P</p>

<p>@nne–</p>

<p>the question said “DuRING DECOMPOSITION,…” so by the time the tree started decomposed, it was assumed that the population of the insects was already at a maxium. After the decompostiion, started, the population of the insects decreased.</p>

<p>Is glycogen “short-term energy storage?”</p>

<p>This was in the M section by the way</p>

<p>oh that reminds me there was a question that was like </p>

<p>a plant stores glucose into </p>

<p>a. starch
b. glycogen</p>

<p>… something like that</p>

<p>anyone remember that</p>

<p>It’s starch. Wiki it</p>

<p>Wan9, i said glycogen was short term energy source. first two questions had me scratching my head and then i read instructions and realized you could use answer twice. It was mitochondria?</p>

<p>I don’t even remember how the question was worded. Oh well, we’ll see what happens.</p>

<p>Yeah, glycogen is short term energy storage in animals.</p>

<p>^ I think the first two questions were mitochondria. The only other ones labeled were the chloroplasts, cell membrane, and nucleus, and none of those apply.</p>

<p>ty there was another question that had to do with the hypothalumus I think or the thyroid gland and like the regulation of a hormone … i forget but the choices were like</p>

<p>a) hyperthroidism
b) hypothroidism
c) negative feedback loop</p>

<p>negative feedback loop. barrons had the exact same example.</p>

<p>oh ok good i chose that :slight_smile: didnt read barrons lol</p>
