mr Goodwill [35]

a specialized form of cell division occurs to form egg and sperm cells : Mitosis, Meiosis, Fertilization

What is Fertilization?

During fertilization, the main nucleus of an embryo is formed by the combination of a paternal sperm nucleus and a maternal egg nucleus. In reality, the process of fertilization in all organisms involves the union of the genetic material from two gametes, or separate sex cells, each of which has half the number of chromosomes that are typical for the species. In microorganisms and protozoans, the earliest type of fertilization involves the transfer of genetic material between two cells.

The fusing of the two gametes' membranes, which results in the creation of a channel that allows material to go from one cell to the other, is the first critical event in fertilization.

As blood pressure increases and the hearts is working harder the most vulnerable arteries area? Located near the heart, because
KIM [24]

As blood pressure increases and the hearts is working harder the most vulnerable arteries area are those <u>Located near the heart, because they are absorbing the most shock.</u>

<u></u>

Explanation:

When the heart pumps blood, the highest pressure is felt close to the heart. This is why the aorta, the artery that carries blood away from the heart is made up of thick walls to withstand this pressure, otherwise, these vessels would rupture. Away from the heart, this pressure lessens, and the blood vessels are not so thick-walled.
