<p>yeah I felt like it made sense…you just never know with the college board!</p>
<p>@sIronMan CB is College Board, who makes the AP and SAT tests. </p>
<p>ohhhh my bad lol</p>
<p>CB–>CollegeBoard–>Bane of high school student existence</p>
<p>But seriously can those who have taken or will take AP Chem can we create an Official AP Chem Thread to get ready please… </p>
<p>I thought the FRQ was like really hard b/c our class never talked about statistcis crap like EMS. Also, the frq was like half ecology.</p>
<p>I don’t really agree with the pedigree, the “matching up” probability seems like a weak argument. If it was recessive and the other parent was a carrier, then that will create 1/4 chance for each kid, and 1/256, which might seem impossible, is still a chance. I’ve never heard about the mitochondrial one.</p>
<p>does alternative splicing of introns in mRNA in flies count as genetic variation?</p>
<p>Form E had a question where you explained the role of the inner mitochondrial membrane. It was a weird question, since part b and c were basically justify your statement from a (so if you didn’t know the role, you probably lose all of the points).</p>
<p>Can genetic variation also come from gene flow?</p>
<p>In what direction did you draw the line for the graph of environmental temperature versus organism’s internal temperature? Did internal temp increase as environmental temp increased or did internal temp decrease as environmental temp increased?</p>

<p>@itsrichardparker yeah that pedigree question was weird! I felt like none of the answers were totally correct. It wasn’t recessive because then not all of the children of the original parents would have had the disease. But it also wasn’t dominant because of those couples where the man had the disease, their children did not. Could it have been X-linked somehow?</p>
<p>Hi everyone. Let’s first remember that getting one question/losing a few points on an FRQ is not a big deal, and if you do get a 4 instead of a 5, it’s not the end of the world. In no circumstance will you die because of an AP score. I promise. </p>
<p>THAT BEING SAID, what in the world was the answer to the carrying capacity question that had rmax= .1, and carrying capacity was 6million? It was on Form D, I think, question 63. I had no idea what to do…</p>
<p>I felt like I put sex-linked dominant, since all males who have it will pass that trait onto his offspring, but females who are not are homozygous recessive for not having it.</p>
<p>@Remembrance I put alternative splicing too for that question. I hope it counts, i thought crossing over didn;t make much sense cuz the strain all had identical DNA</p>
<p>@huhululu i hope it counts. some people were saying that it might not count because the splicing occurs in the mRNA, which is transcribed from the DNA. therefore, the DNA would be the same…</p>
<p>but like, wouldn’t different types of splices result in different types of genes being expressed?</p>
<p>i said in part a that an evidence for variation would be different phenotypes expressed by the production of different proteins. So in part b I put alternative splicing.</p>
<p>DOES ANYONE ELSE THINK TODAY’S FORM O FRQ WAS REALLY HARD???</p>
