For Hardy Weinberg- i have trouble figuring out whether the info they gave us indicates say the P^2 or P. any tips on how to tell?
@ayraify My teacher told me that blastula, gastrula, cleavage, deutrosome v. proteosome is no longer tested. It was however tested on the 2012 FRQ #1
@acpearson98 Thanks!
@awkplatypus p = dominant allele p-squared = homozygous dominant phenotype
EX: If 158 out of 200 individuals in a population have the dominant allele, how many are homozygous dominant?
So: p =.79 q =.21
Therefore, p-squared (AA) = (.79)(.79) = 62.41%
.6421 X 200 = 125 (rounded)
@Asiandoctor For my exam, you can’t bring ANYTHING except pencils, pens, a watch that doesn’t make noise, snacks, and water.
@AnniiT don’t forget 4 function calculator!!!
What’s the story with a TI-30? My teacher said we can use a TI-84 or 83+ (but not an 89), but the CB site says a four function calculator with square root capabilities.
just to make sure, we don’t need to know like all 20 hormones?
@Rpower01 Maybe for the old AP, but not for the new one. The questions about the nervous and endocrine systems will be more focused on ligands and receptors than memorizing the functions of certain hormones.
That being said, it wouldn’t hurt to know insulin v. glucagon, LH, FSH, ADH and TSH/thyroxin.
@TodaysEinstein Do they provide a calculator for you or you have to bring your own? I remember my teacher telling me that they will provide one for you.
@TodaysEinstein Ye the 2012 exam is what I used. I thought a 60+% was a 5 tho.
What percent is a 5? My friend said 79%, but that seems quite high.
last year it was 79% so it might be around that percentage this yr too
What are you guys doing to prep at this point?
@kmadds99 Doing the official 40 multiple choice questions and essays from the CB’s curriculum guide.
Can anyone here who understands the ind. law of assortment and law of seg. explain it really quickly?
@romario123 law of independent assortment: During gamete formation, allele pairs separate independently. For example. you can look at Mendel’s experiment. He decided to test pod color and height, and they were both inherited separately in the offspring. This accounts for variation.
Law of Segregation: During gamete formation, alleles for a trait separate and then come together randomly during fertilization.
anybody have any tips or ideas kn what i should be studying or looking at right now
How in depth is the taxonomy? Cause the in Barron’s it’s really detailed, and I don’t know if it’s worth memorizing…
Anyone know how to calculate a composite score?
we didnt really go over taxonomy in my class this year
