December 09 Biology Discussion

<p>i but active.
cuz it ws low to high</p>

<p>was the chromosome quesiton in m? cuz i took e.</p>

<p>the one with the fire was conifers… gymnosperms benefit from fires because it helps the cones open up and the fire clears the soil from dead plants allowing more growth… believe it or not, i learned this from the Bio sat for dummies book, while laughing at my friend for getting such a gay book and looking over it…</p>

<p>yes loiss, do you remember anything from it that was hard?</p>

<p>The test was almost everything I expected it to be; not harder, and not easier. :D</p>

<p>For the lungs question, it said gas exchange for any living organisms. Doesn’t that range from plants to protists, to insects, to humans, and the only thing gas exchange has in common for all of that is a moist membrane. Specialized structures are involved, it isn’t only defined by lungs and gills.</p>

<p>oh, it must have been on M</p>

<p>but it said a fire burnt down the trees that LOSE leaves.</p>

<p>“Well, for the one for how bacteria and archaea are similiar I put circular DNA. I’m pretty sure both have a round ring of DNA. Oh, and guys for the 50,000 genes in genome, did you put 50,000 diff RNA strands? The others didn’t make sense to me because one dna codes for many genes”</p>

<p>I think the question was between archaea and eukarya, not bacteria and archaea. It was phrased like “Why are archaea more like eukarya than like bacteria…”</p>

<p>dammit, i already got like 10 wrong.</p>

<p>did it say trees that lose leafs?? ■■■</p>

<p>anyone know the one with the experiment . the miller urey-thigns orginated from bacteria one?</p>

<p>what ws the one with the organic compounds??</p>

<p>really?!? lol, oh shoot! I can’t believe I actually misread it like that and my answer was there :(</p>

<p>i think the fire question is supposed to be looked at its ecosystem
taiga would only have the conifers compared to the other answers so most likely the same things would grow there again.</p>

<p>yeahh thats why i put decidious .</p>

<p>Ohhh what was the one with the plant tissue in organs?</p>

<p>what was the answer to the second question on the miller experiment?</p>

<p>ground, vascular, and dermal?</p>

<p>dermal vascular and ground.</p>

<p>i wnt to know the miller urey one too.</p>

<p>OKay, I put dermal, vascular and ground too. First I was going to go with Sclerenchyma, etc, but those are just tissues, not tissue organs. >.> Cunning.</p>
