Answer:
I believe the answer is D for the top one
A mucous membrane or mucosa is a membrane that lines various cavities in the body and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue...
If A is dominant allele, and a is recessive allel, than:
p is frequency of A allele, q is a frequency of a allele, p2 is a frequency of homozygous dominant genotype, 2pq is frequency of heterozygous genotype and q2 is frequency of homozygous recessive genotype.
If the population is in Hardy-Weinberg equilibrium; p+q=1
p=0.15 q=1-0.15=0.85
2pq=2*0.15*0.85=0.255~26%
The answer is D.
Picture it like PAC-man
. The enzyme is pac-man and its hungry for a substrate. It's mouth is the active site. The substrates are cherries.
