<p>What was teh answer to the muscle contraction? It needs ATP? or ADP? </p>
<p>must be ATP, ADP is the decharged form</p>
<p>But I learned that muscle contraction requires no ATP, only Ca+ ions, which was not an option.</p>
<p>no, myocin walks along the actin fibers powered by ATP</p>
<p>Ca ions are used in signaling, not actually powering up the muscle.</p>
<p>Just curious, what did you guys put as the most effective anti-biotic?</p>
<p>i put quadrant 3, since white was the area of no-growth</p>
<p>Just curious, what did you guys put as the most effective anti-biotic?</p>
<p>^ 3, The white area was the largest.</p>
<p>So we’re sure that mutation changes alleles right?</p>
<p>Yes I believe it started with a T</p>
<p>Ugh I hated that eardrum and carrot question… What did u guys get for the one with the 4 pics and which ones have a single digestive opening and two tissue layers?</p>
<p>For the quadrant and agar question, for number 2, did you answer (E) that the bacteria survived because they were penicillin resistant?</p>
<p>For the pictures, it was II and IV. I’m sure of it. It was a hydra and jellyfish</p>
<p>what is the curve???</p>
<p>Yeah, I had E, that bacteria were penicillin resistant.</p>
<p>What was the one about the island 600 miles from Ecuador or something that had animals that weren’t on the mainland? I can’t even remember the answers right now, but does anyone else recall it?</p>
<p>^^ i said something about evolutionary change cuz they are far away from each other.
something like that for the post above mine lol</p>
<p>The island’s separation has caused its own type of evolution … something like that.</p>
<p>Yay thx Ralec114. Phew. Tho it looks like I already missed about 3… Which means I prbly actually missed 5. What does that put me at?</p>
<p>Umm, how about the problem with the starch concentration? Which graph was it? Was it the graph that went down then stable?</p>
<p>I have 5 wrong already >.<</p>
<p>yea i said the graph that went down bc the amount of starch stays the same, but since water is entering, the concentration goes down?</p>
<p>about the starch one:
should have remained constant right.
anyone confirm?</p>
<p>That’s what I thought too.</p>
<p>At first I put the stable graph, but then I thought that the molarity of the starch would go down. Thanks =)</p>
<p>yea i said the graph that went down bc the amount of starch stays the same, but since water is entering, the concentration goes down? </p>
<p>This.</p>
<p>:( guess that makes sense lol
darn it.</p>
<p>wait what??? it was concentration stays same? 
noooooooooooo!</p>
