<p>On essay #2, it’s the electrons flowing down the electron transport chain in mitochondria that provides the energy for H+ to be actively transported into the intermembrane space. They then diffuse through ATP synthetase. In chloroplasts, the splitting of water provides the H+ ions, which then diffuse through ATP synthetase.</p>
<p>ATP and GTP are adenine/guanine RNA nucleotides with two additional phosphates. You could have either said an adenine/guanine nitrogenous base with 3 phosphates or an adenine/guanine nucleotide with 2 extra phosphates.</p>
<p>Operons are only found in prokaryotes. For the protein regulation question, I discussed methylation (-CH3) for transcriptional silencing and feedback mechanisms (the question said regulation of both synthesis and activity).</p>
<p>Although I said a retrovirus for the central dogma deviation question, you probably could have said a virus that goes through the lysogenic cycle.</p>
<p>My two types of phylogenetic evidence were the fossil record and comparative embryology.</p>
<p>For the food chain, I put phytoplankton as my primary producer, then zooplankton, a baleen whale (filter feeder), and a shark. My teacher said that was correct.</p>
<p>And finally, my two variables for the first essay were light and salinity.</p>
<p>What division had the most species discovered? Was it angiosperms or insects? I think it was angiosperms but I ignored that gut feeling and put down insects.</p>
<p>Thanks, I was really unsure about that one actually, but insects was my first choice and then I guess I thought that there were more angio sperms than byrophytes or gymosperms, but good thing that I put insects. </p>
<p>OH, and there was one more important one I had in mind. It’s hard to explain, but this is what I believe it said: A bacteria was exposed to treatment A, and then A+B, and it was a 3 part question ( with the I only, I and III only, etc). I was definitely correct, but II said that B affects the bacteria. What I thought was that since the bacteria was not exposed to B directly, you can’t say that it has an effect. Didn’t the bacteria die after it was exposed to A anyways, so B wouldn’t even matter? I put (I only) for that one, it was the first question of the bacteria section.</p>
<p>for the two types of phylogenic evidence could u say look at the analagous structures so u can c when devations from each other began occuring and also sequencing genomes so you can see where similarities and differences are present</p>
<p>My two variables for the experiment in the FRQ was the age and size of the fish… looking back at the question, it seems like I should have put down like the salinity of pH of the water.</p>
<p>Is the age and size of the fish acceptable answers?</p>
<p>I used the contents of the tank (ie there are plants in one section) and the light of the tank (ie there was a lot of light towards the middle).</p>
<p>the lab probably only got 1/3 of it
2 question most likey 4/5ths of it right
3rd question like 1/2 of it right
and last like 3/5…
if im right 3+8+5+6=22 like more than half i hope.
lol stupid me on the lab i put like numbers of times tested and time intervals between the test an said thedy wouldnt affect the results. WHAT was i thinking/smoking!!!.. Hoping for that 4</p>
<p>I liked the frq question we had better than that form B. I would have done so bad on theB questions. I think the ones we had were easy and basic.</p>
<p>Yea anyone know where the food portion of a fruit comes from? Might have been polar bodies since they supply food to the embryo, but I’m not sure.</p>
<p>For the controlled variables in the experiment, I listed size and species. As for the evolutionary evidence, I used embryology and homologous structures.</p>
<p>Ok so for the “mechanisms of genetic change” I was so stupid and described two different types of mutations…base substitutions and translocations. AH! How badly do you think that will affect me?</p>
<p>Also, for evidence of evolution, I put biogeography (hey, its in the textbook!) and homology. Do you think biogeography is a stretch?</p>
<p>Finally, do you know if you get points off for a wrong diagram but a correct explanation?</p>
