<p>what question are u talking about for the anwer lungs.</p>
<p>Yeah rawkfist, I left that one blank as well.</p>
<p>The question was…What do all living organisms needs for gas exchange?</p>
<p>oh yeah… i put special structures either lungs or gills.
is that wrong??</p>
<p>anddd whatdu get for the caffine.
i but b
more urine volume and more concentration in urine.</p>
<p>I put the membrane one because amphibians can breathe through their skins…</p>
<p>For the stomates I put to let water in, but I’m not sure now…</p>
<p>For the caffeine one, it’s more urine volume and more dilute urine. More water = dilution.</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>for tht expereint, the milelr urey one</p>
<p>the question was like where is the msot organic compunds found.
was it the one with methane? the one with the ridged bubble aroudn it?</p>
<p>yeah i said gills for the dye going to the nextplace
i put con. urine</p>
<p>stomates are for co2.
im preetty sure.</p>
<p>for one of them it asked which would be dominant after a forest would be burned down .</p>
<p>was it decidious herbacous trees?</p>
<p>Yeah, hmmmm but xShadow63 does have a point. It says in my Barron’s that “if stomates were kept open all the time, the plant would lose so much water through transpiration”…and it said the most impt function. Stomates let Co2 in and out so I think he/she is right</p>
<p>i think its decidous hardwood trees and i think i put conifers for that one):</p>
<p>yeah but theyre mostly for co2.</p>
<p>But one answer said letting CO2 in and one said letting it out, and Barron’s said both. Plus, I think water retention is more impt for plants even though I put Co2</p>
<p>anyone remember any more questions
whats the most quesitons i can get wrong and i skipped 3.
to get at least a 700
?</p>
<p>Hmmm…this is what I am wondering as well. PR says 65=700 but Barron’s says 61=700.
Yet, Barron’s also says you can get 73 and get 800 which I don’t believe.</p>
<p>here is the sparknotes chart its pretty reasonable

<p>do you guys remember the answers to the lab ones? the insulin and ephiphrine?</p>
<p>and wat was the asnqer for the sucruse one?
i put water will flow in.</p>
<p>what were the anohter answers to that one?
and for the other q about sucore i said active transport but i think im wrong):</p>
<p>No, I put what you guys put. That water flows in and that it is active transport. There was a ques with a pic of a chromosome and I put 2 dna molecules and that it was mitotic metaphase</p>
