Which statement below best describes the purpose of meiosis in creating gametes?
The purpose of meiosis is to produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).
The purpose of meiosis is to create gametes. Thus, it reduces the number of chromosomes to half.
What is meiosis?In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent).
The egg and sperm that combine during fertilization must be haploid or have only one pair of chromosomes, in order to sustain this state. Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are gametes.
In humans, autosome cells contain 46 chromosomes, while gametes contain 23 chromosomes. Hence, the main purpose of meiosis is to divide the genetic material in half.

A)Electron transport chain
B) Glycolysis
C) fermentation
D)krebs cycle
Image Attached
Answer:
D) Krebs' cycle
Explanation:
The stage of respiration shown is pyruvate oxidation. This is the intermediate stage between the first and second stages of aerobic respiration.
The first stage is glycolysis, which is the breakdown of glucose into two molecules of pyruvate. After pyruvate oxidation, the next stage is the Krebs cycle. The Krebs cycle is a series of reactions that release energy through oxidation of acetyl-CoA.

What is genetic variation?The difference in DNA between individuals or between populations is referred to as genetic variation.
Mutation and genetic recombination are two of the many sources of genetic variation. Although mutations are the ultimate source of genetic variation, other mechanisms such as genetic drift also contribute to it.
Heredity, also known as inheritance or biological inheritance, is the transmission of traits from one generation to the next.
Each of your parents has two copies of each of their genes, and each parent passes on only one copy to you.
Many of your characteristics, such as hair and skin color, are determined by genes that are passed down to you.
Thus, the correct option is B.
