**Official AP BIO 2012 Thread**

<p>Yeah, that’s the one I took. 80/100 on it lol with several near guesses.</p>

<p>okay cool! well not cool about the 2.8 but you know</p>

<p>@hum0rMe17 thanks for answering my questions. I do have to tell you that the answer for question 76 is A and not D :frowning: I don’t even get how we should know what the question is asking from the diagrams.</p>

<p>@jasonjackson789
I’m not sure how A is directional selection. The species didn’t even change…oh well, it’s only one question out of 100. good luck on the test</p>

<p>yeah ur probably right :stuck_out_tongue: I need ur help again if ur willing :D</p>

<p>Which of the following best describes how a small
change in genotype can produce a large change in
phenotype?
A. the deletion of a single nucleotide in a DNA
sequence that codes for a major protein
B. the deletion of a single nucleotide in an
mRNA sequence that codes for a major
protein
C. a change in a gene that controls the timing of
growth during development
D. a mutation in a gene that codes for
cytochrome proteins
E. a mutation in a gene that codes for a
ribosomal protein
Answer is C. Why?
What kind of behavior is demonstrated by a bear
who breaks into a vehicle that contains no food?
A. imprinting
B. habituation
C. insight
D. trial-and-error
E. classical conditioning
The answer is E. Why is it not D?</p>

<p>@jasonjackson789
c because if that gene gets messed up you can have disproportioned body parts, body parts growing at wrong times - the organism is going to look really messed up, hence a change in phenotype; for a and b they might result in a misfunctional protein that could lead to some disease but it really won’t affect the phenotype as much as c.</p>

<p>the second question is really sketchy, if you stretch E enough you could say that the bear is used to breaking into cars with food so when it sees vehicle(stimulus 1) it associates it with food(stimulus 2) - that would be classical conditioning </p>

<p>what review book are u using??</p>

<p>An airtight, temperature controlled glass box containing actively growing tomato plants was placed under a light source. PLastic wraping that only transmits green light was placed over the box, and two days later air samples from inside the box were collected and analyzed. the most likely change in air quality is?
Why is the answer an increase in Co2?</p>

<p>Plants reflect green light. If it is only allowing green light in it won’t be able to photosynthesize.</p>

<p>Also remember that plants undergo cellular respiration as well as animals.</p>

<p>Should i even bother studying Biological Diversity for the AP? We skipped this whole topic in class and i heard its barely on the test.</p>

<p>^ I’m wondering this as well. It’s the most dense section of Cliff’s, and it’s a lot to remember.</p>

<p>This weekend, I’m going to be an AP Bio maniac. All day, e’ry day.</p>

<p>I’d focus on the Animal phyla is I were you–some of the frqs require information about them (ie flatworms have bilateral symmetry, etc.) You’re probably correct about the others though; they’re definitely not worth your time.</p>

<p>Okay, good. I’m solid on animal phyla.</p>

<p>What topics do you guys predict will be the frqs</p>

<p>does anyone know if we can use acronyms on the FRQ’s for example say RuBP istead of ribulose bisphosphate?</p>

<p>Done with APUSH, now time to start studying for Bio…LOL</p>

<p>@TopDrawer: my teacher is almost positive the lab one will be the Wisconsin fast plant one about recombination frequency</p>

<p>On a scale of 1-10 how prepared is everyone feeling right now? </p>

<p>I’d say I’m at an 8, maybe 8.5</p>

<p>A better thing to ask would be: On a scale of 1-5, how ready do you think you are :p</p>

<p>I’d say I’m at a 4. I really don’t know much about animal structure/function/reproduction.</p>

<p>@Matugi could you elaborate a little more on that?</p>
