Acell divides to form two cells during a process called
a. mitosis.
b. chemiosmosis.
c. photosynthesis.
d. protein synthesis.

Option (A)

Explanation:

Mitosis is usually defined as a process by which a single cell splits into two other cells. This initial single cell is known as the parent cell and the resulting two cells are known as the daughter cells. These daughter cells are comprised of the same number of chromosomes, as well as a similar types of chromosomes.

During the time of occurrence of this mitosis process, there may occur mutation.

Thus, the correct answer is option (A).

a time line cause it goes from 685 to 978

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
