<p>am i the only one who did bad?? my gosh! this sux!!!! OK ! everybody, i noe im asking like million questions, but is 7 omit, and 4 wrong, bad??</p>
<p>Ok I think I got some more. The one cell would swell and burst?</p>
<p>do u remember answer to the question about the parts of a plant that uses plasmodesmata? was the answer the one with one thing inside the other?</p>
<p>i said it will swell and burst</p>
<p>plasmodesmata are just holes between cell walls</p>
<p>so wat did u put as the answeR?</p>
<p>Yeah, I agree the cell would swell and burst. Reasoning: since the cell was high with solutes but low on water, water would diffuse into the cell and the cell would swell and burst. Kinda like what would happen if a saltwater fish was put in freshwater.</p>
<p>I can't remember. Something with a bundle sheath?</p>
<p>Didn't it say .9 percent solute? I remember seeing the normal percent solute in my review book but dont remember the exact value. Isn't .9 percent solute really low?</p>
<p>i can't remember what i put... im so mad!!! :mad:</p>
<p>.9 percent? Wow, if that tried to trick us by saying that that would be so stupid!</p>
<p>Plasmodesmata = bundle sheath and mesoderm cell.</p>
<p>would that make a difference to the answer?</p>
<p>im pretty sure it said "0.9" which i figured is nearly water, so it would stay the same</p>
<p>What kind of solution is the .9 percent solute placed in?</p>
<p>More research bout the ape question:

<p>Early transitional humans had brains that on average were about 30% larger than those of the australopithecines. In fact, it is beginning with Homo habilis that our ancestors finally had brains that were consistently bigger than those of the great apes. Ajit Varki and his team of geneticists at the University of California San Diego campus have discovered a small genetic difference between humans and apes that may account for the progressive increase in the size of human brains. People, but not apes, have a gene that stops the production of N-glycolylneuramine acid. Using "molecular clock analysis," the U.C.S.D. researchers determined that this gene entered the human evolutionary line as a result of a mutation 2.7 million years ago. While it is presumed that the australopithecines lacked this gene, there is no direct evidence.

<p>Seems that larger brain cavity may indeed be the answer</p>
<p>.9 percent!?! Okay, guess I missed it then =(</p>
<p>animal cells are approximately concentrated as (isotonic to) a 0.9% solute solution, so the answer would be that it would swell and burst</p>
<p>ok now i just would have to wait and see</p>
<p>what about hte bacterial conjugation question?</p>
