<p>Yeah, I took a look at Form B and it was MUCH easier. I could have gotten all of them I think. But instead, I only answered about 2 on the normal one…</p>
<p>I feel extremely fortunate to not have had Form B. All the questions seem harder…who gets Form B, by the way?</p>
<p>seriously?!</p>
<p>For 2 mechanisms of genetic change, I used bottleneck effect and founder effect. Is this ok, even though they’re both part of genetic drift?</p>
<p>I wouldn’t stress; if I’m doing the math correctly a 60/100 and 28/40 will get you a 5.</p>
<p>60 x .9 = 54
28 x 1.5 = 42</p>
<p>54 + 24 = 96, good for a 5.</p>
<p>Form B isn’t that bad, I think its a lot more straightforward with the questions compared to the other. The 2009 questions were somewhat weird.</p>
<p>Could genetic change be on the cellular level (like meiosis crossing over and ind. assortment of chromosomes)?</p>
<p>@cosine</p>
<p>I think they were specifically looking for molecular stuff like crossing over/mutations…cause those are what actually cause the change…the genetic drift/gene flow stuff is more how the genetic change moves through populations.</p>
<p>I’m incredibly thankful for form A…form B would have been really difficult for me… Who even gets form B? </p>
<p>I thought form A questions were pretty general and therefore easier. Like “explain 2 processes that use ATP”…that’s like what half this course is about.</p>
<p>well gene flow and genetic drift are changes in the gene pool and it clearly affects genetic variation, so I would assume it would work - given that you explain it and how there is greater variation and change in the gene pool that can lead to evolution. My example was there could be a pop. of blue skinned animals and another population that didn’t have blue skin. Through gene flow the other population increases genetic variation because now blue skin alleles are present in the gene pool.</p>
<p>for my trophic level (and i checked these organisms’ diets on wiki, it totally worked)</p>
<p>algae - clownfish (i put “Nemo” in paranthesis lol) - flounder - shark</p>
<p>Just to lighten things up, did anyone include any notes to the AP graders? I included a few biology pickup lines (crossing them out, of course)-- hopefully they have a sense of humor, especially after reading thousands of essays. :)</p>
<p>no jokes
but i did the why so serious thing</p>
<p>OMG. Form B is just too perfect. My one semester of non-AP Bio ap just did lab 6, and our teacher is a H2O freak. <a href=“Supporting Students from Day One to Exam Day – AP Central | College Board”>Supporting Students from Day One to Exam Day – AP Central | College Board;
<p>hey can someone let me kno how okay these responses are:
1.drew histogram using temperature intervals
said motility and size of fish were variables that need to be controlled
said physiology affected b/c gills dilate or contrict and scales become flaccid or harden depeding on temperature–>related to being ectotherms
2.said ATP is adenosine bonded to three phosphates, said bonds are high energy and when broken down can fuel exergonic reactions,uhh also said its a steroid or something lol
said its in krebs cycle and calvin cycle and explained chemiosmosis a bit here
reexplained chemiosmosis lol
said algae-shrimp-fish-sharks
just said 10% rule so only 10% energy transferred b/c lots lost in digestion (bs)
3.drew a kladogram… meh
for descriptions i just talked abt which ones are most related etc.
penguin and chicken were most related
4.defined everything pretty well but messed up spliceosomes
transcription/translation stuff was easy
used retrovirus but instead of saying reverse transcriptase i said DNA polymerase and described them using lysogenic cycle–> deviates from dogma b/c they r doing opposite by using RNA to make DNA rather than normal eukaryotic cells that use DNA to make RNA</p>
<p>uh yea. size of fish=no good. it says “small” in the question.</p>
<p>you explained that protons built up in the matrix and then went through atp synthase right?</p>
<p>o and for number 3 i described mutations diff kinds and stuf and abt how beneficial ones fuel natural selection–>leads to increased genetic variation
then i tlaked abt genetic drift–>decreased genetic variation (talked abt founder effect)</p>
<p>position69: ya i explained the proton gradient and all that stuff</p>
<p>Wait isn’t Chemiosmosis in the light reaction and the ETC not the Calvin and Krebs Cycle?</p>
<p>And for the fish I wrote down placement of the fish (ie they might not move around or w/e), the age of the fish and the size of the fish. </p>
<p>And for the genetic variation one I didn’t know if they meant like mutations in the DNA or genetic drift in the population.</p>
<p>ok so i put p53 and ras gene for protein regulation…will that work?</p>
<p>i also used homologous structures for determining phylogeny. is that a stretch?</p>
