<p>I’m more worried about THE FRQs!</p>
<p>By the way, I wish everyone a Good Luck on this exam (first-timer here). It’s driving me nuts.</p>
<p>@Oscarlany: exactly my problem. The new Barron’s book says you have to write in essay format but it also says to label your free response. Cognitive dissonance…</p>
<p>Just use paragraph then? Idk, my teach said to outline.</p>
<p>montague, I think that most of the free responses will only have an “a” part (the 6 short ones), and therefore, we can just write those in an essay format, but for the two long ones, we should probably label them and write a paragraph for each part</p>
<p>you dnt outline ur points in bullets. you label each part likw 1. a) and then you answer it in full sentences not buleted answers is what they mean</p>
<p>Okay, I trust you guys - thanks so much!</p>
<p>@mattsmats: It’s not A because the question said that the plasmid would contain the gene for human insulin AND the amp gene. We know that the e.coli will die if it does not already have the gene that is resistant to the amp. I does not contain any amp while IV is already growing e.coli that is resistant to the amp.</p>
<p>I hope that made sense.</p>
<p>Sorry uh… its kind of against Collegeboard policy to answer questions like this plus the one that I took is a different form than the one in the states</p>
<p>Essay format could mean using complete sentences.
@ DeZsaS: Cheating on a biology test is like stealing free candy: pointless.</p>
<p>the84thline, DON’T LISTEN TO YOUR TEACHER. whoa, don’t outline unless the FRQ asks for an outline. </p>
<p>EDIT: That’s considered cheating, too? Ugh, crap. I’ll edit the post. Thanks!</p>
<p>have you not seen the forums for SATS where they go over each answer…and u dnt know the test might b the same…and if u dnt want to say…then at least tell us the topics</p>
<p>@teekskim questions aren’t same, but we can get a jist of what to expect.
most people are scared about the frq section cause we haven’t seen the new format before</p>
<p>By outlining, I was refering to labeling 1a, 2a, etc. Without taking the test, I can almost assure everyone that there will SOMETHING about endosymbiosis, transpiration, the endomembrane system, immunity, or evolution on the FRQs. THESE ARE IMPORTANT CONCEPTS!!!</p>
<p>what do u mean by endomembrane…like cell communication?</p>
<p>Alright, just did the 2nd Barron’s practice test and scored about a 70% on the MC. I got 5/6 math questions right as well, and the FRQ’s were much easier this time around (there was only one that I didn’t really know how to answer).</p>
<p>Two questions…</p>
<ol>
<li><p>Can anyone explain Chi-Square to me? I’m so confused on how to calculate it.</p></li>
<li><p>I’m still unsure of how to study for FRQ’s. It seems like you’re at the mercy of the luck of the draw.</p></li>
</ol>
<p>teeskim, Different? Aren’t the AP exams international? My teacher told me that some people even fly over to LA to take the AP test somewhere next to the Staples Center.</p>
<p>Endomembrane System:
Transcription factor to transcription to mRNA transcript to splicing to ribosome (and tRNA) to rough ER to vesicle to Golgi Apparatus to vesicle (again) and finally to the cellular membrane for exocytosis.</p>
<p>chi square is generally used for predicting phenotypes. You must know the ratios of 1:1, 3:1, 1:1:1:1, and 9:3:3:1 to use chi-square for those, or you must be given a numerical perdiction.</p>
<p>chi sq. is sum of (observed - expected) ^2 / expected…it basically is the prediction for the critical value of probability that the experiment occured successfuly for all phenotypes…which you have to compare to the standard values which you figure out on the chi sq. chart where is compares df (# of phenotypes -1) to 0.05 normally. if ur x^2 value is more than it from the chart…reject null hyp. if its equal or less accept</p>
<p>anyone understand #47</p>
