<p>did anyone else put larger algal population meant less nitrogen</p>
<p>also for seed germination I’m pretty sure the answer was excess amounts of water. [Germination</a> - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Germination]Germination”>Germination - Wikipedia)</p>

</ol>
<p>Yeah, I got excess water for the seed germination question and larger algal population means less nitrogen as well.</p>
<p>Also, from the potato question about the roots turning green, apparently chlorophyll levels can increase when the root is exposed to light, turning it green, but I’m not sure if that’s the correct answer. I put the one about the green turning animals away, but I’m not sure.</p>
<p>Annie that was the logic I used, going to sleep for right now, talk tomorrow?</p>
<p>What was the emphysema question? Was that on the E section because I took the M and I legitimately don’t remember that question. What was being asked?</p>
<p>Also, for the introns/exons, don’t you just add up the exons and ignore the introns? I think the answer I put came out to 300-something.</p>
<p>@candianeuropean Yea that’s what you do for the introns/exons question. I think the answer was like 350.</p>
<p>what did you think of molecular test? do you think it will have a good curve?</p>
<p>@ nycguyy</p>
<p>Oh ok, that’s what I thought, thanks. I thought the M test was pretty straightforward and not particularly difficult (not really any major surprises, which was a relief), though I wouldn’t call it particularly easy either (especially if you don’t study for it). I just didn’t have time to double check everything. From the looks of it, I got 3 questions wrong for sure and there are about 5 or 6 other questions I’m not that sure on. I’m hoping that’s enough for a 750+ or 760+ score. I didn’t have to flat out guess anything or leave anything blank, so hopefully that’s a good sign.</p>
<p>I studied mainly from Kaplan which I thought had realistic practice tests at the back, though Kaplan goes into more detail than what ended up being on the test (this was my first SAT subject test), both the practice tests Kaplan had went into more detailed questions than what ended up being on the test. On my first Kaplan practice test I got 11 wrong and left 1 blank which Kaplan said was a 740 and on my second test I got a 780 (6 wrong, no blanks). I don’t know how similar the curve is going to be on the actual test, or if the curve varies from year to year, we will see.</p>
<p>For the ledge, I thought it was saying an intermediate width. If that was the case, it would be the red at higher and black at lower. There are still two ledges, but they are now the same width–still at the same heights as before (high and low).</p>
<p>Also, for the glucose starch bag, I am almost certain that the solution was isotonic. you have starch and glucose ( 15 %) and glucose 10 % outside the bag. However, starch is selectivey impermeable, and since diffusion is defined as the moving of solutes from a higher concentration to a lower concentration…10 % is only allowed to move to 10 %- isotonic. :)</p>
<p>At least, that’s the logic I used. Thinking back on it now, I probably was just tricked by the whole…starch can’t move or whatever. However, can someone please explain what the first 30 seconds was more than last 30 seconds. I know I specifically didn’t pick the photosynthesis stops at one point, but can someone explain the context of the question and the answers because I’m having a strong difficulty remembering .</p>
<p>And again, for those who did ecology, does anyone not remember putting " the water flea was just as related to the lobster as it was to the branching?</p>
<p>For the branching diagram, I remember that the lobster and something branched off, then something else branched off, and then the shrimp was at the very end. I remember choosing the option that was about how the lobster and the shrimp branch off before the lobster and the other animal branch off, since it seemed like the most reasonable one.</p>
<p>Yeah, that was a different question altogether. But I skipped that one because I wasn’t sure. There were 2-3 questions in that one section.</p>
<p>I believe water will still diffuse to lessen the starch saturation</p>
<p>[Beware</a> of Eating Green Potatoes](<a href=“http://drbenkim.com/green-potato-solanine-dangers.html]Beware”>Beware of Eating Green Potatoes)
It looks like solanine is present, but it sounds like the green is caused by the presence of chlorophyll</p>
<p>@nycguyy
I thought it was legitimately hard.But that’s because I want an 800. So far, after looking at everything, I’ve only missed 1 on the molecular test and it was really really stupid. I’m hoping to have all 80 questions from molecular on here to make sure I didn’t make any dumb mistakes. (I am the king of stupid mistakes) So far I don’t think I got anymore wrong. Lol I walked out of the test knowing how stupid I was for thinking “oh… grasshopper legs are on the thorax… So easy!” But then I accidently bubbled in A for abdomen lol!</p>
<p>Anyway, curves are predetermined so mostlikely 78 or 77 score is still the 800. I used Barrons and PR. I got 740 and 770 on PR and 800,770,800 on Barrons. And 800 on CB practice test. And took 4 free tests I got from idk where. I had a PR because everyone said it was good… but I noticed so many mistakes in there and the tests… It is really the worst book for Bio. I ordered the Barrons 1 day shipping last monday. I’m so happy that I did because Barron’s is much better!</p>
<p>1 1/2 week Try Super Hard Studying FTW! Btw, I know my grammar here sux XD. It’s ok it is just a forum, and I’m like texting.</p>
<p>Oh ya and for the cells moving during development. It’s because of cell signalling. My teacher just explained that. It was in chapt 20/21 Campbell. Lol haven’t read my hw so far. Thank goodness my teacher mentioned that in class before I took the SAT.</p>
<p>@ Whatdoyouthink was the full answer, cell to cell contact or something like that? do you remember the full answer? I think it was E to that one.</p>
<p>I used the Barrons too and I felt that the tests in it were nothing like the actual test. Barrons has test questions that are basically facts but the actual test has questions that are more involved and questions that you wouldn’t know the answers to.</p>
<p>idk its just my opinion.</p>
