There are two alleles, B and b, at a gene locus in a population at Hardy-Weinberg equilibrium. The relative frequency of the dom
viva [34]

Answer:

210

Explanation:

Frequency of dominant allele is represented by "p"

and frequency of recessive allele is represented by "q"

Given

p = 0.7

Thus,

q = 1-p\\q = 1 - 0.7 \\q = 0.3\\

As per Hardy Weinberg's second equation of equilibrium -

p^2 + q^ 2 + 2pq = 1\\

Substituting the given values in above equation, we get -

0.7^ 2+ 0.3^2 + 2pq = 1\\2pq = 1- 0.49-0.09\\2pq = 0.42

So the total number of heterozygous individual is equal to

0.42 * 500\\= 210

If two species of bacteria use glucose as an electron donor, but species a uses oxygen as the final electron acceptor and specie
Vlad [161]
Species B would need about 60% more glucose to generate the same amount of ATP as species A. This is because molecular oxygen is a highly oxidizing agent and therefore, is an excellent electron acceptor compared to other less-oxidizing substances such as sulfate, nitrate or fumarate.
