<p>I felt like that the M section was easier than the E section. I went through both and the M section was a lot more doable xD because the questions were alot more straightforward less calculation stuff and easy diagrams 
well just my opinion though 
@Piano its fine XD just one question and you won’t get any deduction since you left it blank</p>
<p>does anyone remember about byproduct of photosynthesis or something about oxygen in the general section?</p>
<p>Yes, it’s 5.</p>
<p>do you know what was the question and answer to the byproduct one?</p>
<p>i put the peptide bond as the one on the left side near the amino group. cause that’s where it would bind to the carboxyl of another peptide isn’t it?</p>
<p>and does any remember the exact wording of the question about reproduction? the answer was crossing over/recombination i think, but i dont remember the question</p>
<p>@thingschange Sorry, I don’t remember. I do remember that the answer was oxygen is a byproduct of photosynthesis. So I believe you’re right.</p>
<p>@daesung No, I definitely missed more! :P</p>
<p>@yolobio the one all the way on the left was N-C and the nitrogen was also connected to two Hydrogen… now Im thinking about it idk LOL</p>
<p>hmmm… I think Yolobio might be right so it probably is 1

<p>hmmm wait, where exactly was the 5?</p>
<p>Can someone put up like a list of answers LOL there is a lot of repeat.</p>
<p>I think 5 was between C and OH and 1 was between C and N. So it would be 5… i might be wrong though</p>
<p>yolobio is not right, sorry. The bond between N and C has nothing to do with the H or OH that must be released during a dehydration reaction. The bond within the COOH (seen on the left-hand side of the linked photo) is the correct answer. On the illustration in the test, the OH part was on the bottom, but it doesn’t matter. The correct bond is the one bonding C to OH in the COOH bond.</p>
<p>Hey for the diagram of the heart, there were two parts… I think the one with the blood spreading to the body was aorta and then there was one that said pumps to the lung (I think) was that right ventricle or the southwest part of the heart?</p>
<p>@thingschange Yea right ventricle
@StudiousMaximus I was thinking of the bond between N-H on the left side of the amino acid xD But i just remembered that wasn’t part of the answers so YAY I put 5 :)</p>
<p>@thingschange I didn’t take the E section, but I might be able to help.</p>
<p>The aorta carries the oxygenated blood to the body.
The right ventricle pumps blood to the pulmonary arteries.</p>
<p>So you’re right.</p>
<p>haha yea, i had a feeling i was wrong… hey guys, what was the answer to the question: why does sexual reproduction help with evolution? the answer was variation right?</p>
<p>Oh I forgot to ask this question. The one where they gave the experiment on rats. They asked which one must they HAVE so the experiment was accurate. And people are saying the diet but wouldn’t the one with all of them from the same litter be also correct? Since if they aren’t from the same mother then wouldn’t the experiment be to vague??</p>
<p>^ I think diet is more reasonable. Diet affects embryological development, which is most pertinent to the experiment. “All rats from the same litter” is a little ambiguous–which rats, the mothers or the children? If the mothers, there’s no reason why they should all be directly related. If the children, why should all of the children be of the same litter? Should the children of one mother be the children of another mother as well? I think not, so diet seemed like the best choice.</p>
<p>Ok ugghh 2 wrong T.T probably more that I dont know bleehh… But it like gave … a chart on Litters xD soo yea :/</p>
<p>^ But which rats had to be from the same litter? All of them? The mothers? It just doesn’t make much sense. A consistent diet is a necessary control for the experiment, so I chose that answer.</p>
