<p>eh I thought i did really well. the graph questions werent hard, the genes i practiced alot during the school year, and the first 25 questions were almost laughable. I dont know though, there were indeed some things I wasn’t sure about… like the nucleotide/gene crap on the M section. I glanced at the E sectoin after i finished the test, and my god, E was easier. DOH</p>
<p>Julina, I put brain cavity as well. I’m pretty sure it was either than or the bigger neuron channels, right? I thought about the jaw option, but don’t apes have much larger jaws anyway? Aughh, I don’t know… Oh, and I remember putting sex-linkages for one of the answers too! </p>
<p>Did you guys take M or E? I took M. My proctor didn’t really seem like he knew what he was doing, so I could have easily switched to E, but I didn’t want to spend time comparing the two sections for difficulty. There was barely enough time as it was =/</p>
<p>I took M as well but I also peeked at E. The questions were soooo easy although I didn’t want to read all the graphs they had at the end. What did ppl get for the farm runoff Q?</p>
<p>decrease in eutrophication.</p>
<p>Hey, which question was the sex linkage one? I only remember the pea plants and the colorblind one (which only had probabilities as answers) for questions about genetics.
Also, do they really care if you don’t write the statement in cursive? I was in such a rush to get out of the place, I forgot.
Also, i think it’s okay to discuss questions now, I’m from california and just finished the test an hour ago.</p>
<p>Eutrophication of lakes? BTW, sorry to dissapoint all of us who answered brain cavity, but early humans had about the same brain size as apes :(.</p>

<p>AGH <em>tear</em>, what would’ve been the answer then…</p>
<p>Did anyone get what the heck was going on in the bacteria experiment at the end of M? Was 5 the one producing toxins? How many colonies would be expected to grow in undiluted soil?</p>
<p>How were we supposed to know that about the brain cavity…?</p>
<p>I put 5 produced toxins, 6 was like natural constituent of agar, and omitted the thing about undiluted soil. ***.</p>
<p>5 was producing toxins because of the clear area around it. I think it would be 1000 times more colonies because since the soil was diluted by 1L, that would’ve made it 1000 times less dilute.</p>
<p>what does plasmodesmata do?</p>
<p>What was the one about increasing the pH from 4.5 to 5.5? I was stuck between the thing becoming more neutral and the H+ decreasing, and I put the latter in the end.</p>
<p>I put that 6 was a water contaminant. Plasmodesmata are channels in cell walls. And I thought H+ concentration decreases for going from 4.5 to 5.5.</p>
<p>Yeah, it was H+ decreasing. It didn’t say MORE neutral, it just said neutral which was wrong.</p>
<p>What else did ppl put for colony 6 in Molecular?</p>
<p>I put a water contaminant too. I don’t see how agar, a nutrient broth, could have bacteria in it… If it did, then the bacteria would grow before any water was added. Agar is produced by algae and it’s a carbohydrate.</p>
<p>BTW, if the PH rises from 4.5 to 5.5, the H+ concentration is decreasing, but I don’t think H+ decreasing was one of the choices, so I just put the buffer choice…</p>
<p>I’m pretty sure it was a choice. I think it was right above the buffer choice?</p>
<p>But if it was a water contaminant, wouldn’t it show up on both agar plates? I put that bacteria #5 was toxic because there was such a big space around it. Was that right?</p>
<p>
</p>
<p>It did show up on both plates I think… One of the facts was that the bacteria on the water plate had an appearance similar to a bacteria on the soil plate, something about the red color</p>
