June 2006 - Biology

<p>I'm trying to be as pessimistic as possible so as not to get any hopes up at all...I'm probably exaggerating, but I'm saying I'll miss 20...that would put me in the high 600's...is that pretty bad for a HYPSM school?</p>

<p>If HYPSM is your top choice, and Bio was the only test you took, I think maybe you could consider either cancelling your score and take another subject test, OR retaking it to aim for 750+ in October. Although something like 680 is a fine score, I think that colleges like HYPSM will have many applicants in the 750+ range for all their SAT 2s, so it wouldn't hurt to try to get your score into that range as well.
Also, seriously try to reconsider taking the exam. Biology SAT 2, in my opinion, was one of the easiest SAT 2s to study for. My worst science is biology, and I never got an A in freshmen biology class. However, I used princeton review that year to prep for the SAT 2 exam. I read through every chapter and did the exercises at the end. Make sure you remember all the concepts and flow charts, because although I have forgotten 99% of the biology I've learned, I recall that there is a lot of that sort of stuff. Anyways, in the end, I didn't score an 800 like everyone else in my class , but I came fairly close =)</p>

<p>I've been feeling horrible all morning about this. According to what you guys put, I've missed quite a few. I can't cancel, because I think I did pretty well on the French test. But, is there definitely the possibility that your guys's consensus on questions isn't always the correct answer?</p>

<p>yeah... the problem is a lot of the questions that we're debating over can't be looked up, because the problem is in the wording of the questions or something.. like i made a "score range" for myself of like 40 points.. and i'm like 80% sure i'll land in that range.. it's not completely set in stone, it's only an idea of how well you did...</p>

<p>i dont know if this question was asked already...i just dont feel like reading 13 pages...</p>

<p>ok there is a flea, seeds, a mouse, coyote, and a snake
my food chain was
seeds->flea->mouse->coyote->snake</p>

<p>i couldnt decide whether a snake can eat a coyote or a flea can eat a coyote because technically, a flea does eat a coyote in a way because it bites it and eats the blood. but, however, only female fleas can do that, whereas a snake can bite the coyote, poison it, and then eat it. but can fleas eat seeds? what do they eat other than blood? can a coyote eat a snake? </p>

<p>this food chain question is so messed up</p>

<p>^^sorry that was me</p>

<p>the foodchain question: seeds--mouse--snake--coyote--fleas</p>

<p>but a flea cant totally devour a coyote like a snake can</p>

<p>u could probably wiki "fleas" and find out what diff things they eat and so on (i don't feel like doing it, because i'm supposed to be writing two papers - errr or maybe i'm just lazy...)</p>

<p>also.. do you guys remember the answer choices for the glucose one? because i don't remember what i put anymore...</p>

<p>does anyone remember the last few questions on the "m" section with the petri dishes and the e.coli colonies? it's been bothering me. a lot. if you have the answers please post them too :)</p>

<p>actually, if you remember any "m" questions and answers at all, those would be greatly appreciated.</p>

<p>thanks <3</p>

<p>can we talk about the M section?? no one has really discussed those answers...</p>

<p>haha i didnt see hulloworld's message...for the e.coli dishes, i put that Sample II was comparable to the water sample as an asnwer?? i also said something about inhibiting the growth of colonies...i think that was an answer to what was this experiment testing? i cant think of more..</p>

<p>um...also, does anyone remember the questions with the girl's breath, the limewater/bromythol blue solutions, and determining the CO2/acidity of the girl's breath? those were mildly confusing...</p>

<p>again, anything at all would be nice-</p>

<p><3 hulloworld</p>

<p>girl's breath, i said the one that best showed CO2 was the limewater because the bromythol turned blue for acidity and presence of CO2, so it was unclear. and acidity was bromythol because the other one remained clear i believe</p>

<p>any more m answers??</p>

<p>i agree with the acidity thing since limewater didn't do anything with acidity, hmm but for some stupid reason, i think i put bromythol for the CO2....ughh</p>

<p>thanks though-</p>

<p>do you remember any of the other questions in the M section? im worrieddd, it was weird</p>

<p>a LOT of M questions have already been discussed earlier, i'm trying to compile a list although it's taking a while to go thru the posts I missed . .
I think a list would be good though so I can see how bad/good I did, hopefully before WED, which is the last day to cancel.</p>

<p>solution 3 killed the bacteria by making the wall explode, so it is the best all-purpose solution</p>

<p>that is the only one i remember</p>

<p>no you can't conclude that it killed the bacteria by specifically disintegrating the cell wall right? I mean, the solution could've just raised the toxicity, raised the PH, making it impossible to live in, not necessarily disintegrating cell wall? maybe i thought too much into it though.</p>

<p>Ecoli experiment conclusion
a) solution 3 destroys cell walls of bacteria
b) solution 2 and water control are comparable</p>

<p>me and some others put B =&lt;/p>
