Abiallelic locus, aa, has allele frequencies of a = 80% and a=20% in a certain population. another biallelic locus, bb, has allele frequencies of b = 90% and b = 10% in the same population. both loci are found to be in hardy-weinberg equilibrium. a recessive digenic disorder (100% penetrant) occurs only when one has the aabb genotype. it’s found that 15 people out of 10,000 in this population have the disorder. what was the expected frequency of the disorder? (assume that the "a" locus and the "b" locus segregate independently.)

The images show the wings of a bat and a bee. from this evidence, what can you conclude about the evolutionary relationship between these organisms? a. the wing structures of the bat and the bee are different, indicating they didn’t inherit wings from a common ancestor. b. the wing structures of the bat and the bee are different, indicating they inherited wings from a common ancestor. c. the functions of bat wings and bee wings are the same, indicating they obtained wings from a common ancestor. d. the functions of bat wings and bee wings are different, indicating they didn’t obtain wings from a common ancestor.

Atypical human cell is approximately 12.00 μm in diameter and enclosed by a membrane that is 5.000 nm thick. (a) what is the volume of the cell including the membrane? (b) what is the volume of the cell membrane? (c) what percent of the total volume does its membrane occupy? to simplify the calculations, model the cell as a sphere. enter your answers using four significant figures.
