Which statement below best describes the purpose of meiosis in creating gametes?
Answers
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.

Answers
Answer:
D. thrombocytes
Explanation:
The main function of thrombocytes is to stop the bleeding of injured blood vessels. In mammals, thrombocytes are anucleated cell fragments called platelets.
Thrombocytes is responsible for the clotting of blood.
What are thrombocytes?
The microscopic blood cells known as platelets, or thrombocytes, aid in blood coagulation. Your body naturally stops bleeding with platelets.
Plasma, red, white, and platelet-containing blood cells make up whole blood. Platelets, the lightest component of whole blood, are pushed to the walls of your blood vessels because they are the heaviest part of the blood.
This allows plasma and blood cells to flow through the center, allowing platelets to reach injury rapidly to stop bleeding.
Therefore, Thrombocytes is responsible for the clotting of blood.
