PLEASE HELP ILL GIVE BRAINLIEST

Biology
1 answer:
Finger [1]2 years ago
8 0

Answer:

Purpose: Meiosis is a special version of cell division that occurs only in the testes and ovaries; the organs that produce the male and female reproductive cells; the sperm and eggs. ... Therefore the purpose of meiosis is to produce gametes, the sperm, and eggs, with half of the genetic complement of the parent cells.

Genetic variability is a measure of the tendency of individual genotypes in a population to vary (become different) from one another. Variability is different from genetic diversity, which is the amount of variation seen in a particular population.

Meiosis generates genetic diversity through a process called crossing over which allows new combinations of variations to appear in gene pool. ... Chiasmatal points appear randomly on homologous chromosomes, hence amount of genetic material exchanged in every case/cell could be different.

If the adhesive forces between a liquid and the walls of a capillary tube are greater than the cohesive forces within the liquid
olga_2 [115]

Answer:

Option A, the liquid level in a capillary tube will drop below the surrounding liquid and the surface in the capillary tube will have a convex meniscus.

Explanation:

A liquid will wet the surface of the container in which it is contained only when the adhesive forces between the molecules of the liquid are weaker than the adhesive force between the surface wall of the container and water.

A  convex meniscus is formed when the attractive forces between the molecules of liquid (cohesion) becomes greater than attractive forced between the water molecule and the container's surface (adhesion)

Convex meniscus simultaneously move the surface of the liquid in the downward direction due to which its level become lower than the surrounding layer.

Hence, option A is correct

Mitosis results in the formation of how many cells; meiosis results in the formation of how many cells? see concept 13.3 (page 2
9966 [12]
Mitosis results in the formation of two diploid cells while Meiosis results to the formation of four haploid cells. Mitosis is a process that takes place in the somatic cells; a cell that has doubled its genetic material divides to produce two diploid daughter cells while meiosis is a process that take place in the gamete cells where a doubled cell undergoes two rounds of division producing four haploid cells.
