The correct answer is E)52
When there is Hardy-Weinberg equilibrium like in this case of a single locus with two alleles denoted A and a with frequencies f(A) = p and f(a) = q, the expected genotype frequencies under random mating are f(AA) = p² for the AA homozygotes, f(aa) = q² for the aa homozygotes, and f(Aa) = 2pq for the heterozygotes. Let's put that A is dominant and a is recessive allele. In Hardy-Weinberg equilibrium we have:
p²+2*p*q+q²= 1 p+q=1 p=1-q
f(a) =0.4=q q²=0.4²=0.16=16%
p= 1-0.4=0.6 p²=0.6²=0.36=36%
Percentage of a homozygous genotype in the population is 16%+36%=52%
The plasma membrane maintains homeostasis in the cell by keeping cell contents in and foreign material out, and by providing controlled avenues for the transportation of fuel, fluids and waste.
Answer:
A nerve impulse
Explanation:
It's important to note that these signals not only connect the brain and spinal cord, but they also send signals to muscles and glands. People talk about nerve impulses when they talk about the electrical signal that goes down an axon.
