<p>So howd u think it was</p>

<p>not too bad, but not that great either.</p>

<p>I thought it went pretty well. I think I may have messed up on one question about heredity, and then when they gave the diagram of a makeshift nervous system. I was more confident with history though for some reason. I mean, i hope I did really well;knocking on wood...</p>

<p>what was the answer to how mammals hear?</p>

<p>the tympanic membrane i believe.</p>

<p>what was the answer letter choice for the heart blood flow? i remeber putting down c, but not the real answer.
the last two on the molecular part totally threw me off. what were the answers? i put A for 89 and lower the change in G(answer choice C) for 90.</p>

<p>i thought it was pretty easy lots of heredity questions it seemed. molecular was pretty easy too. there were just a few random ones that i left blank or guess one otherwise not too bad</p>

<p>the heart flow was right atrium right ventricle lungs left at left vent aorta</p>

<p>and what was the pyruvic acid one</p>

<p>pyruvic acid is made from glycolysis, and goes to the krebs cycle. Fermentation, however, makes ethanol and lactic acid.</p>

<p>o, the word acid threw me off because i thot glycolisis made pyruvate. Is the pyruvate the same as pyruvic acid?</p>

<p>wat was the one with 2 germ layers and one digestive opening?</p>

<p>what was the one which had most energy, cellulose, starch, vitamin C, etc?</p>

<p>cnidaria so, had to be the hydra and the jellyfish.</p>

<p>for teh germ layers i left if blank but i think it was the worm. Fat has the most energy I think</p>

<p>was the hydra II?</p>

<h2>Yeah, the hydra was number two.</h2>

<p>How did you guys do on the heredity questions in the beginning?</p>

<p>how's the curve for the bio m for 15 wrong and 5 skips</p>

<p>The morula/blastula undergo mitotic divisions, right?</p>

<p>thats what i had,
also for the two layers, i put II*medulla something) and IV(giant squid), not the earth worm</p>

<p>how's the curve for the bio m for 15 wrong and 5 skips</p>
