I totally made that up on the test so I’m not certain it involves Epigenetics, but when I looked it up it said some courtship behaviors can be controlled by epigenetics. I found like 8 articles that say courtship rituals can be controlled by epigenetics.</p>
<p>I personally didn’t care very much about the siRNA being on the test because all of the other choices were easy to write about, but just because it won the nobel prize in 2006, doesn’t necessarily make it fair game. My teacher didn’t even recognize the name of it (She was research scientist for many years, AP Bio 20+ years, multiple awards). I’m sure there are many Nobel Prize winning ideas/project in the last 10-15 years that wouldn’t be fair game to test a AP student on.</p>
<p>For the epigentics FRQ I wrote about epistasis and used albinism as an example… Does that make sense?? I said that even though people may have the gene for skin pigmentation, the presence of an epistatic gene causes the skin pigment gene to not be phenotypically expressed</p>
<p>And for the graph FRQ I totally freaked out and couldn’t figure out why the plants were consuming oxygen because they should have been performing photosynthesis and releasing oxygen, so I definitely screwed up there :</p>
<p>I haven’t read everything in this thread so I don’t know if this has been said or not, but there were two completely different tests… two different MCs and two different sets of FRQs. I guess they have to have two different curves, right?! Cause otherwise that would just be completely unfair.</p>

<p>several version of a test is a standard practice. the tests are extremely well researched. a person able to get 5 on one version will get 5 on a different version (even if it is from a different year).</p>
<p>folks, in AP pass, it says that the minimal number of points for a 5 is 95. I’d like to know how much could that change due to the curve or the test being easy? I mean can the minimum change from a 95 to a 110 or even 120? coz if that’s the case, I’m probably screwed :/</p>

Epigenetics (the inheritance of traits not due to the DNA sequence) is not the same as epistasis. You’re describing epistasis. I didn’t take the test this year (took it last year), but the two most common examples of epigenetics are DNA methylation and histone acetylation. </p>
<p>I guess they want people to be really up to date with what’s going on in modern biology. Maybe there will be more questions on stuff like DNA sequencing.</p>
<p>It’s funny but I put epistesis too, and I used albinism as well! Well in the descriptioj of epigenetics given in the problem itself it said “heritable changes in phenotype withouht changes in genotype” or something close to that extent and I figured albinism fit that pretty well</p>
<p>silver spoon i did the same exact thing.</p>
<p>… and now i just read what aldfig0 said. that’s sad, i knew about gene silencing but i didn’t make the connection. CLIFFS DIDN’T PREPARE ME FOR THIS :K</p>
<p>WARNING: Today my school got a call saying they want to cancel my AP Biology score because of the posts I made on here… I didn’t even say anything specific about the test, and you guys are…</p>
<p>So I’d stop, and even report some posts so CC can delete this thread…</p>
<p>Btw; they said they tracked my IP address, so they could do the same to you >.<</p>
<p>Is your name actually Lesley Cordero?</p>
<p>@Lesley, seriously?</p>
<p>Wonder if they just called you or if they called anyone else.</p>
<p>All I have to say to Lesley is… YOLO.</p>
<p>How are the frqs graded? Is it like one point for each part of a section of a question you get right?</p>
<p>Hello!</p>
<p>Did everybody here use the Cliff Notes to study for the exam? What about Barron’s?</p>
<p>seriously? well I should probably delete my posts… we can’t even talk about how we think we did?</p>
<p>That should be fine.</p>
<p>Just don’t reference FRQs until they’re posted, and never talk about MC, just in case CB comes over here again and decides to kick someone to the ground again.</p>
<p>The FRQs are all worth ten points total, but not each section is weighted equally. For example, if the question was (and this was not on the test! but I saw it on a past released FRQ i think) Also, there are many ways to get your points. Which I will explain.</p>
<p>Part A:List 5 eukaryotic organelles and describe their function
Part B: Explain three differences between eukaryotic and prokaryotic cells.
Part C: Give an example of a prokaryotic organism’s adaptations to combat the difference in part B
Part D: Give two supporting reasons for the endosymbiotic theorem.</p>
<p>Part A may be worth 5 points, Part B three, Part C one, and Part D 2. That adds up to 11 points. If, by some chance, you get all 11 points, you will only get a 10/10. But, if you mess up Part C, you can still get a ten/10. I hope that makes sense!</p>
<p>Oh ok, that sounds fair. ^ thanks :)</p>
<p>Hello!</p>
<p>Did everybody here use the Cliff Notes to study for the exam? What about Barron’s? What are their weakness and strongness?</p>
<p>I just don’t understand why anyone would discuss specifics, if it was clearly in the rules. Collegeboard helps us get college credit before college, gives us an opportunity to show our skills through the SAT, and essentially helps us get into college. Let’s respect them a little please by not breaking their clearly stated rules.</p>
