<p>@mcvcm92: um...i'm really sorry but i think you didn't read the question correctly. I know for sure that it asked for the correct statement.</p>
<p>I had two answer choices left: one with chlorofluocarbons and the other one with green house gas
i chose the green house gas one, and FORTUNATELY chlorofluocarbon is responsible for acidic rain, so this statement was false. If the question was asking for false statement, there is definitely more than one like the chloroflurocarbon and the statement that humans are not responsible for global warming</p>
<p>I put acid rain for the global warming question...I also thought it asked for the one that did not contribute to global warming. </p>
<p>And according to What</a> Is Global Warming?, chlorofluorocarbons do contribute to global warming as they are "artificial greenhouse gases."-> If that is true,wouldn't there be two right answers?</p>
<p>Actually, now that I think about the question, I'm pretty sure it was along the lines of "pick the true statement to do with global warming". So I think greenhouse gases was the only completely true answer...I could be wrong though.</p>
<p>ah sweet. yea, i was surprised that was on teh ecology section. also, for the last question with the bacteria or w/e in the plate, when their exponential growth slowed down what was taht due to? i said buildup of metabolitic wastes or soemthing like that. i know some of the other answers were lack of light or lack of food...</p>
<p>I didn't do ecology, but it's metabolic wastes (ex. yeast producing ethanol that eventually kills it...i know that's not a bacteria but it's the same concept).</p>
<p>Really? I thought it was an animal cell cause I seem to remember it being round (or maybe that was just the nuclear membrane...uhoh).</p>
<p>For the muscle, I think it was that the ATP changes the shape of myosin through binding to it (wikipedia says something about "conformation" change).</p>
