Which process can be described as two cell divisions, genetic variation, and haploid cells? a. meiosis b. mitosis c. binary fission d. fertilization

this process is known as meiosis

Answer : The correct answer is -

A. meiosis.

Meiosis is a type of cell division that occurs during the process of formation of gametes particularly in sexually reproducing organisms (such as human beings).

In this process of cell division, a diploid parent cell divides (through two rounds, meiosis I and meiosis II) and produces four haploid, reproductive cells (also called gametes such as egg and sperm).

Genetic variation is produced due to recombination between homologous chromosomes (particularly in prophase I of meiosis I).

Thus, option A is the right answer.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
