<p>o yea inversion in the base DNA molecule thingy
does anyone remember that question?</p>

<p>wasnt there something with the kidneys or liver? or am i mixing this up…</p>

<p>yea the inversion was like from ATTCG to TTACG (switching the A and T) i think</p>

<p>Yeah there was a question about kidneys I believe… Hmm. </p>

<p>I remember the blood group question, the question about the number of haploid/diploid cells (that was just the double right? Or was I thinking too easy?), questions about birds on high and low cliffs and their nests, questions about potatoes, questions about speciation, the anatomy of the grasshopper (I said both his digestive … and other part were in his back part, and his legs attached to his abdomen? Probably completely wrong…), I’ll see if I can remember more of them! </p>

<p>And I second the question if they curve subject tests or not!</p>

<p>For the grasshopper questions, did u put A for all of them?</p>

<p>I put BAA I think… not sure!</p>

<p>what was the first one asking for?</p>

<p>whatd u guys get the one about the blue dye and photsynthesis? when was photosynthesis most observed? i put underr the curve. but not sure.</p>

<p>I didnt know</p>

<p>I guessed slope.</p>

<p>For the most observed, I put under the curve.</p>

<p>for the rate, I put the slope.</p>

<p>“For the most observed, I put under the curve.”</p>

<p>huh? I dont really remember this.</p>

<p>under the curve = surface area (if I remember right from calculus and integrals)</p>

<p>slope=rate</p>

<p>The rate of photosynthesis would be the slope of the curve. The ‘amount’ of photosynthesis would be the area under the curve.</p>

<p>They asked for the rate - I put the slope too, there wasn’t a question about how many times it was observed though, if I remember correctly…</p>

<p>Wait there was a question that asked for the amount of photosynthesis?</p>

<p>was there a question that asked about reptiles or amphibians or was salamander one fo the answers?</p>

<p>Yea. Salamander should be the answer.</p>

<p>Did it ask which was an amphibian?</p>

<p>i cant remember, for some weird reason i thought it was reptile, but my friend told me amphibian</p>

<p>what did you put for the zone/region (forget the exact wording) with the greatest animal diversity?
tundra, tropical rainforest, …</p>

<p>I put rainforest but it was a complete guess</p>

<p>yea thats right. was it reptile or amphibian?</p>
