<p>What does it mean to “drop” a question? I think I got a near-perfect score on FRQ #1, so I hope they don’t remove it entirely. (I actually had no idea what it meant, but I guessed well.) :/</p>
<p>@DiscipulusBonus to “drop” means to not grade, i.e. to ignore a question for grading purposes</p>
<p>anyone with form D here?
just curious, but how do they even distribute the forms?</p>
<p>@wordstylist I had Form D! I have no idea how they distributed the forms, because there is no one else at my school who had Form D other than me (I live in the Midwest). Hopefully each of the tests is on its own proper curve.</p>
<p>@lolapz Have you found any more people with Form D from your school or elsewhere? I think I’ve encountered maybe 3 other people in total (including you and two other college confidential users). I can’t help but wonder if there were even 100 people with Form D in the United States, haha.</p>
<p>@catheriney2004 half my school got o and other half got d. other than that literally couldn’t find anyone lol. </p>
<p>So, wait… College Board takes out credit for certain MC questions even if you get them right? Lame… :/</p>
<p>Also, anyone know the main difference between the SAT 2 Biology concepts and the AP Biology concepts? Do I need to know anatomy? </p>
<p>@DJFlash I believe so…think about the SAT’s experimental section. They don’t give you extra credit, even if you answer them all correctly.</p>
<p>anybody had form E…? </p>
<p>wait so form D was experimental? so different curves maybe…? </p>
<p>form O FRQ are posted! anyone want to do a google doc and solve all of them?</p>
<p>@remembrance I had enough difficulty doing them once lol</p>
<p>Is it okay if I said exotherm not an ectoderm? I loooked it up and apparently they are the same thing… but I don’t know if the grader will acknowledge that</p>
<p>@itsrichardparker Exotherm and ectotherm are not the same thing, sorry. Exothermic refers to processes that give off energy. Ectothermic refers to organisms that do not produce their own body heat. A couple of my friends did the same thing. I think you will get partial credit for your explanation, though. I wrote some gibberish about the organism being an endotherm so I likely got 0/3 on that…</p>
<p>So i put exotherm and in parentheses I put cold blooded. is that okay?</p>
<p>exotherm doesn’t mean exothermic. I also said cold blooded and explained it correctly so hopefully the grader knows what I am talking about and I still get points for the question. </p>
<p>How hard is AP Bio? How many hours of work do you have on average per day? Thanks!</p>
<p>The question didn’t ask you to identify whether it was endothermic/ectothermic anyway. It wanted a description of the process, but incorrectly stating it was an endothermic process will lose you points. </p>
<p>For the part B first problem of the on the FRQ, it seems that there is some disagreement, and I am trying to clear it up.
The questions said “Identify the two populations that are most likely to have statistically significant differences in the mean stem trichome density.”</p>
<p>To find a statistically significant difference means to find a difference in the data. It just means that there is a difference in the respective data of the populations. For this reason, the answer would be Population I and II because they have the lowest means out of the three populations as the standard error remains the same. This basically means that the data deviates from the mean more than for Population III. Population I has a standard error of 1 and a mean of 9. So, with 95 percent confidence the data can be between 8 and 9 and 10 a 11% difference from the mean at either extremes. Population III has the least likely statistically significant difference in the data of its plants, because it has a mean of 14 and a Standard error of 1 meaning that the data can be between 13 and 15 a 7 % difference. </p>
<p>So, question 14 has the least statistically significant difference in its respective population compared to the other populations while the other two obviously have the higher difference.</p>
<p>And, for the mitochondrial DNA question, not all moms with the allele passed it to their offspring. I checked the whole graph, and not all moms passed it to their offspring. And, the choice simply didn’t make sense.Here is why:</p>
<p>The women whose offsprings’ phenotypes we were trying to find had the allele for the disease ( the circle was colored black). And, the choice said, "it is a mitochondrially inherited trait so there is a 0% chance that the children will inherit it."If it was a mitochondrially inherited trait and the mom had it ( this case) there would be a 100% chance of inheritance of the trait, because every child would have it. It was a recessive trait.</p>
<p>oh never mind for the B part. I actually completely messed up my explanation. It is population 1 and 2 because they have the most difference. But, I believe that my mitochondrial explanation is correct, </p>
