<p>What do you guys think of it? I thought it was harder than the practice tests from barrons…I prepared it with barrons…but it seems that barrons didn’t cover everything…</p>
<p>I thought it was okay. Did you get a chance to answer every question?</p>
<p>umm…i did. but i left one question blank…it was about vestigial structure…towards the end…i just didn’t have time to figure out which ones can be it…so yea…are there any questions that u still remember?</p>

I think the vestigial structure was the pelvic bone. Well, that’s at least what I put. I know I missed 3 questions, but those were from questions I didn’t answer in my first pass through or was less than 50% sure on. I missed the cephalothorax (Should’ve thought about cephalopods! duh!) and two questions on the cross-section of a plant stem. The others I’m almost 100% sure on, though it may turn out that I’m wrong. :(</p>
<p>ahhhh…pelvic bone was my first guess…but i wasn’t sure…cephalothorax…that was the scorpion right? cause i was sure that butterflies had a pair of antennas…scorpion was the only thing left…</p>
<p>and the cross-section…i knew that pith is for storage…but the graph didn’t have anything pointed to the middle…so i just picked one that’s not pointing towards xyleom/phleom area…but idk if it was right tho…</p>
<p>sighhhhh…now i just hope i get a 700…T_T…my friend said that he took 14 practice tests…and he got 760…but i only took 4 >-<…ahhh</p>
<p>Oh. Haha. I forgot to look up if crayfish had antennae! I too picked scorpion. I just thought about cephalopods after the test and how they were usually only in water. I believe the pith was A (the one pointing closest to the middle of the cross-section).</p>
<p>okay…good. i think that’s what i put. umm…crayfish…i think i put down gills for that?</p>
<p>yepp! I put crayfish too.</p>
<p>I thought it was somewhat easier than the Sparknotes tests I’ve practiced with. I omitted 2 and probably got around 6-12 wrong. Hopefully the curve is generous enough for a 710-760 with that. The molecular-specific section was especially easy in my opinion. Most of it was just utilizing analytic skills; prior knowledge seemed only to be superficially necessary.</p>
<p>1-3 was commensalism, mutualism, and mutualism, anyone verify?</p>
<p>the cephalothorax question was also accompanied with a “no antennae” question, right? i don’t remember the question clearly, but the answer should be scorpion.</p>
<p>vestigal structure for the snake is definitely pelvic bone- they don’t have legs!</p>
<p>what else does everybody remember?</p>
<p>I don’t remember the vestigial question. Was it ecology specific?</p>
<p>I took M- not sure, but it probably was. I was just answering the question lol </p>
<p>the question with the charts in correspondence to the DNA per cell and the time
which charts were mitosis/sperm production?
i chose the one that went up and back down and up and down back to the starting point each time/the one that started out straight and decreased</p>
<p>@ymlee822
Yes, it was ecology specific.
@jumpingjellyfish
The mitosis chart was the first one. It looked like a sin or cos (depending on how you want to look at it) function. In mitosis, DNA replicates so you essentially double your DNA per cell and when it divides, each cell returns to the original amount of DNA that the parent cell had.</p>
<p>The sperm production one was the graph that had two drops. It started very similarly to the mitosis chart, but had another drop after. The parent cell replicates the DNA in meiosis I, doubling the DNA per cell. Then, it splits, creating two daughter cells with the same amount of DNA the parent cell had before replication. In meiosis II, however, the cells do not replicate again; they simply split one more time. Thus, the DNA per cell halves again.</p>
<p>Darn! I forgot about meiosis II… I even drew out a diagram to help me. Wow, I’m an idiot haha. Well that’s one wrong for me. Thanks Shirafune.</p>
<p>@jumpingjellyfish</p>
<p>yea~ i got commensalism, mutualism, and mutualism</p>
<p>i remember putting down pancreas for protein digestion and large intestine reabsorbs water?</p>
<p>yep, you’re right for both</p>
