The epithelial cell will have 38 chromosomes
A 2n or 2(19) = 38 chromosomes. This is because n is called haploid number of chromosomes; the number of chromosomes present in the gametes. Epithelial cells like other body cells divides through the process of mitosis; therefore; the parent cells yields daughter cells with the same number of chromosomes (diploid). The other haploid (n) number is present in the gametes which divides by the process of meiosis.

Therefore, on the basis of the above information, the desert is the correct option. The desert biome is the hottest and driest region of the earth. This region receives very low annual rainfall.

Answer:
Genetic variation
Explanation:
It could lead to natural selection, but natural selection isn't the cause. Many years down the road you could see a particular variation having a higher population, which is the result of natural selection/survival of the fittest via better camouflaging from predators.
