Answer:
B. No
Explanation:
First, let's watch what it looks like when a population is not evolving. If a population is in a state called Hardy-Weinberg equilibrium, the frequencies of alleles, or gene versions, and genotypes, or sets of alleles, in that population will stay the same over generations (and will also satisfy the Hardy-Weinberg equation). Formally, evolution is a change in allele frequencies in a population over a very long period of time, so a population in Hardy-Weinberg equilibrium is not evolving.

0.43/m
Explanation:
Given parameters:
Surface area of the sphere = 588m²
Volume of the sphere = 1372m³
Unknown
Surface area to volume ratio = ?
Solution:
To the surface area to volume ratio is simply a ratio of the surface area and the volume of a substance.
Surface area to volume ratio = 
Input the parameters:
Surface area to volume ratio = 
= 0.43/m
