<p>wouldnt the concentration of glucose decrease cus water would diffuse into the membrane and make the solution dilute?</p>
<p>i didnt know what a colon was----i left it blank : (</p>
<p>Oh yeah! What was that. I guessed bc I narrowed it down to 2 choices... but it was really a random guess.</p>
<p>Which version did you guys take? E or M?</p>
<p>I really wanted to look over E. But I forgot and decided to check over my answers. And by the time I was done and realized I wanted to see what the ecology questions were... I had like 5 minutes left and didn't get through them. :(</p>
<p>No, the substance in the bag has a higher concentration then the water. So, water would rush into the bag, as the stuff in the bag diffused out. Water diffuses from hypotonic to hypertonic.</p>
<p>exactly...i knew ppl would be like...what the hell is a colon....thank god i knew it...but just in general...it was tougher than we expected....is that a concensus amongst us all?</p>
<p>but didnt it say that the starch couldnt pass through the membrane, so water would go in but starch wouldnt go out, and the concentration of starch would decrease</p>
<p>didn't they say the bag was not permeable to the starch?</p>
<p>So the graph went up like...and then stabilized...it was A right?</p>
<p>Like this: </p>

<p>Yeah, I'm confident with US history--I think I can score really high, mainly because the curve's so generous (knocking on wood). Biology on the other hand, I came out of the test more apprehensive and paranoid: like, "Oh man, did I check this party--did I do this on that part!" Yeah, I really think they overdosed the genetic topic.</p>
<p>i thought it just went down</p>
<p>i think solution dilute cuz solute can't diffuse out (question said the solute can't go thourgh the bag) </p>
<p>is colon for reabsorb water?</p>
<p>Ea is for breaking bond, right??</p>
<p>Another thing- they didn't have one of those DNA-RNA questions like GCTAT! :(</p>
<p>The concentration of the starch stayed the same. The PERCENTAGE of starch in the bag would decrease, but the concentration couldn't change because starch wasn't able to diffuse out.</p>
<p>What was the colon answer? I'm so confused.</p>
<p>wait, what was the exact question....cus it appeared to me that water would diffuse in, lowering glucose concentration, but I put A because i think the question asked over time, wat would happen to the concentration of water in the bag? was it that? The other graphs didnt make sense...there was a constant, one increase slope, decrease slope, exponential i think...and then A which was an increase and then leveling....i forgot the question itself...</p>
<p>activation energy is for breaking bonds i think</p>
<p>who else took ecology??</p>
<h2>the colon answer--reabsorption of water.</h2>
<p>Wait? So how dod the graph look like for the starch? Did it swoop down, or remain the same?</p>
<p>Ea for breaking bonds yes....Colon is the large intestine = water absorption</p>
<p>YAY ON COLON YAY! </p>
<p>The graph looked like this</p>
<hr>
<p>:)</p>
<p>i put that it swooped down...but now im not so sure</p>
<p>i think i put A. the graph increased a little then constant.</p>
<p>there's a question choice like
A. cell is under cell division
B. cell is enlarging
c. cell differeniation</p>
<p>what's the answer?? (can't remember exactly the question anymore)</p>
