That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky. ... The wings force the air downward and that pushes the plane upward.

pychu [463]

Answer:

When gametes combine to form a zygote, the chromosomes number of the zygote is now referred to as diploid.

Explanation:

The term diploid refers to the complete chromosome charge of a cell, in this case a somatic cell. Sex cells, or gametes, contain only half of the chromosome charge that each parent confers on their offspring, and are called haploid cells.

Two gametes, haploids, each contribute their half of the chromosome charge to form a diploid cell, the zygote.
