<p>what about
what causes changes in DNA
what causes the greatest genetic diversity</p>
<p>and anyone know possible curve</p>
<p>and the one about alga and human enzymes, how come alga has a great temperature span</p>
<p>magerie: i put mutations for both</p>
<p>what about the set of questions in the beginning that had the choices of extinction, comptetition, etc...</p>
<p>blah123: What were the choices?</p>
<p>^^i put something about humans can regulate their temperature and alga cant</p>
<p>i think thats what i put</p>
<p>I put down that mutations cause changes in DNA</p>
<p>what did you get for what was considered "diploid" (1st question on M section)-was it a pair of chromosomes with similar structure or something like that? and what about what the Q on what the plasma membrane did-did it trap photons?</p>
<p>What was answer to the matching question that said there were more organism A (forgot about the specific species) than organism B when it was cold, and more B than A when it was warm? Adaption or competition?</p>
<p>topboy: umm i put adaptation for the stingray and i put competiton for that one</p>
<p>Can you explain why it's competition? I thought species A and B varied in population because one was more capable of adapting to the cold environment and one to the warm environment.</p>
<p>does anyone know if diploid chromosomes are homologous w/ similar structure and if plasma membranes trapped photons..plz??</p>
<p>^^i put diffusion of o2? something like that</p>
<p>adaptation is an anatomical structure, physiological process or behavioral trait according to wikipedia...but i think it was competition b/c there was an exmple like that in my pr book</p>
<p>i put down pair with similar structures for the diploid question</p>
<p>about the question in that competition/euphorication..etc. list..with the blue-green algae replacing the protists in a pond or w/e b/c of an increase in phosphate-was that succession?</p>
<p>rw...i dont think it was succesion...isnt tht dealing wiht lichens, and decidous forests??</p>
<p>i thought that was eutrophication because it said the pond was polluted</p>
<p>what was the one when they mentioned a bunch of cycles? (water, nitrogen, etc..)</p>
<p>no i don't think so..it was about a pond that increased in phosphate-it was part of the group based questions with like adaptation/competition/euphorication/succession...</p>
