How chromosome number remains the same in the members of the same species?

The process of meiosis allows chromosome number to be same in members of same species.

Explanation:

Human beings consist of 23 pairs of chromosomes that is 46 chromosomes. The gametes (sperm and egg) in them contains haploid number of chromosomes. This is due to the process of meiosis.

The meiosis is a type of cell division. It is also known as reductional division. This decreases genetic material from diploid to haploid. This is the reason that all  chromosome number remains the same in the members of the same species.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
