What process takes place first in the development of a human being

The correct answer would be fertilization.

Explanation:

Human fertilization takes place in the ampulla of the fallopian tube. The fertilization process involves the union of a human egg (ovum) and sperm which results in the zygote formation.

In this process, the sperm burrows into the zona pellucida to reach the outer membrane of the egg and fuse there for zygote formation.

Thus, the correct answer is Fertilization.

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.

this is math not biology xd
