<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.
Answer:
B.) is the process of taking materials into the cell
Explanation:
A.) is incorrect because endocytosis move things into the cell by collapsing the cellular membrane around the substance and then budding off.
C.) is incorrect because the material is not always directed to the endoplasmic reticulum. Most the the material is directed to the lysosomes.
D.) is incorrect because phagosomes are created during phagocytosis, a special type of endocytosis.
Answer:
having traits that help a single organism survive
A major disadvantage of artificial classifications is that they have little predictive value; arbitrarily selected properties do not necessarily correlate well with each other. This generally means that they are of little use for purposes other than that for which they were designed.
