<p>Thanks, but did everyone else find the phosphorus passage pretty hard? Or did I just have a brain fart when I did it</p>

<p>Oh the phosphorous passage was killer. Definitely the hardest of the passages for me.</p>

<p>OK then can we talk about it more?
I think it was the second or third to last question but the answers were either 1, 2, 3, or 4 and it was something like “In which of the soils was ____ larger than ____” and I picked 4 with logical reasoning, but no reasoning behind it.</p>

<p>and the last question of that passage I picked A, don’t remember the question.</p>

<p>that one was either 0 or 4 because I remember there being both those answers of that section</p>

<p>I want to say that I said 4 as well.</p>

<p>anyone remember the passage about like pH and different graphs and 3 experiments? what did you guys get for which experiments only studied one type?</p>

<p>@Alexmass</p>

<p>I was thinking it was either 0 or 4 as well. But since there was no 0 answer I went with 4.</p>

<p>@omgitsvicki </p>

<p>I believe it was study 1 because that only involved one of the 2 enzymes while the other two had two curves each representing a enzyme.</p>

<p>So no one remembers the last question to the phosphorus passage? It was something like “which fertilizer had more ___ and which had more ____”</p>

<p>@jy2013, really? I put 2 experiments (1st and 2nd) studied one enzyme.</p>

<p>honestly I don’t remember the experiment that well… But I think two of them were studying two enzymes. If the experiment had two curves in its graph, then it studied two enzymes. I think experiment 2 and 3 had two curves</p>

<p>I thought all of the sections were fairly easy except for the “RE” and DNA section which made absolutely NO sense to me. I still think I did fairly well on it, but that section was hell.</p>

<p>I agree Epic.</p>

<p>What was the last section about?</p>

<p>I don’t know why there is so much confusion surrounding the cross section question. The answer is 1 x 4 because the current faces the greatest resistance going through a thinner and longer wire.</p>

<p>I don’t think there was a 1x4 answer choice. What letter was 1x4??</p>

<p>It was an answer choice, and I believe it was D</p>

<p>I think it was A</p>

<p>It wasn’t A, because I remember A having a cross section of 2</p>

<p>Glad to know I’m not the only one who struggled on the RE plasmid blah blah section. I took AP Bio last year and it made barely any sense, if any.</p>

<p>Does anyone remember the 7th passage?</p>

<p>@saraco
It was the the one with the electric currents</p>
