<p>1) what was the secondary bond for proteins..something like that. i think i put hydrogen bonds</p>
<p>misterme i know its not that, the placenta helps transport wasteful material</p>
<p>tjwogus i thought it was peptide bonds? but i dont think that was a choice i just put covalent</p>
<p>actually ya its hydrogen bonds</p>
<p>what was the dotted line.
coenzyme?</p>
<p>what causes acid rain, SO2- or NO- it angers me because all the websites im looking at say they both contribute... i think i put SO2-//the one with sulfur</p>
<p>Anybody have any idea what the incorrect graph for the growth of the plants with the no3, po4, and both nutrients together was. I put the pie graph</p>
<p>ps. I believe it was the SO2 because H2O+ SO2=H2SO3 (sulfurous acid? contributes to acid rain)</p>
<p>i put the pie graph too</p>
<p>dotted line was an inhibitor and the main cause of acid rain is so2</p>
<p>Was this dotted line thing on the molecular section? I don't remember it</p>
<p>Any ideas about the limiting nutrient? I still can't figure it out.</p>
<p>the most limiting nutrient out of the options was nitrogen, and the dotted line was on the M-section</p>
<p>How did you figure out the limiting nutrient thing(to satisfy my curiosity =)) What does it mean?</p>
<p>The pie graph? I put the first graph (A). </p>
<p>There goes my 800! ):</p>
<p>What made you put the first one? I'm asking because I wasn't positive about the pie graph.</p>
<p>How many do you think you have wrong so far?</p>
<p>...I can't remember why I chose (A).</p>
<p>I skipped one, got the AaBBCc one wrong, can't remember what i wrote for 2 of them...
must have made some other careless mistakes (let's put 3 in for good measure...)</p>
<p>so 2+, essentially. you?</p>
<p>I really wanted an 800 on this. How disappointing!</p>
<p>For the graph one I selected the line graph because it didn't make any sense. You can't use a line graph for categorical data.</p>
<p>The one with the bonds in tetiary structure of protien was confusing. There are double convalent bonds between sulphite groups (S=S), hydrogen bonds, and I think there are also ionic bonds aren't there?</p>
<p>For the graph I put A because it didn't have the control (water)</p>
<p>They were asking for the bonds in the secondary structure. Since we're dealing with beta-pleated/alpha helix conformations, the answer was hydrogen bonds.</p>
<p>Yes! Now I remember! That's part of the reason I chose A. Now let's pray we're both correct..</p>
<p>Phew, yeah that's what I put. Makes sense thanks.</p>
