The answer is B) Convection
<span>All the muscle fibers under the control of a single motor axon are referred to as </span>Motor Unit. <span>A </span>motor<span> unit is made up of a </span>motor<span> neuron and the skeletal </span>muscle fibers <span>stimulated by that </span>motor<span> neuron's </span>axonal<span> terminals. Groups of </span>motor<span> units often work together to organize the contractions of a </span>single<span> muscle.</span>
<u>Answer:</u>
The correct answer option is: frequency of the recessive allele.
<u>Explanation:</u>
When there are no mutations, no selective forces, no gene flow, no non-random mating and large population size, the population is said to be in Hardy- Weinberg equilibrium.
When Hardy-Weinberg equilibrium is met, it is written in the form of an equation which is as follows:

where
represents the frequency of the homozygous dominant allele,
is the frequency of the heterozygous allele while q or
represents the frequency of the homozygous recessive allele.
