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"

nucleus

would be most reasonable answer tbh

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
