What is genetic variation?

select one:
a. the selection of desirable traits in individuals that increase likelihood of survival
b. the control center of the cell
c. drastic changes to an environment
d. differences with a population of the same species

question 2

- the allele for a widow's peak is dominant over the allele for a hairline with no peak. it is an example of

- the relative frequency of an allele is the allele occurs in a gene pool, compared with the number of times other alleles for the same gene occur. relative frequency is often expressed as a percentage.

- height in humans is one example of

- a gene pool consist of all genes, including all the different alleles, that are present in a population.

answers for those for are
multigenic trait
polygenic trait
single gene trait
bigenic trait
relative frequency
gene pool

Your answer would be "Drastic changes to an environment"

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.  

earthquakes in florida are rare because the state is not located near any tectonic plates. in fact, florida is tied for first place as having the fewest earthquakes of any state. much of florida is limestone and seafloor materials that is not conducive to earthquakes.
