<p>Mandizz,</p>
<p>Plant A requires more than 13 hours of darkness to grow. The answer was E (light at the very beginning) because even after you interrupt it for one hour, the plant still experienced a continuous 15-16 hours of growth in darkness.</p>
<p>I just hope theres a big curve. i think theres a better curve in may than in june since less people take it in may.</p>
<p>Thanks Juliana. My problem was that I didn’t realize that the second light problem (with the flash) was related to the one before it that said it needed the 13 hours. I just thought they were two completely unrelated problems.</p>
<p>Thats what I get for skipping around the test too much and rushing!! =(</p>
<p>This thing definitely needed an update.</p>

<p>debates:
<p>Come on guys, lets try to think of some more</p>
<p>high correlation between bacteria and depth of soil</p>
<p>lactic acid in your legs…no oxygen</p>
<p>bacteria important for conversion of ammonia to nitrates</p>
<p>were the depths of the soil 0.5 and 2.0? I remember seeing those numbers having the correlation, but I can’t remember if it was for soil depth or something else</p>
<p>farm runoff…the only choice was increase in eutrophication. decrease wasnt a choice.</p>
<p>yeah they were</p>
<p>also you forgot actin and myosin interaction for muscle contraction</p>
<p>you mean decrease was a choice?</p>

<p>debates:
<p>Decrease was a choice, it was letter E.</p>
<p>i thought the curve for may was less than the curve in june.</p>
<p>here’s my reasoning: the AP bio kids take it in may, the regular bio kids take it in june.</p>
<p>I don’t remember the “leg” part of the muscle question. Was there only one choice that said muscles resorted to lactate fermentation when depleted of oxygen?</p>
<p>We’ve got about 50 questions, let’s try to get the remaining 30.</p>
<p>yes…only one choice</p>
<p>was there also an increase in eutrophication choice?</p>
<p>Wasn’t there a question on plant reproduction or division? It may have been answered already</p>
<p>nails/claws. mammals/aves? i don’t know.</p>
<p>something led to increase in water? formation of starch, was it?</p>
