Question

can you explain this question?

14. True (A) or False (B): During meiosis, chromosomes from each pair in a diploid celbare randomly assorted into the new cells that are produced 15. In animals, mitosis generates cells for which purpose(s)? Choose all that apply.

Answer 1

Answer 14: Meiosis- A type of cell division in which the number of chromosomes in the parent cell is reduced by half to produce four gamete cells. The number of chromosomes is restored in the offspring when the sperm and egg unite to form a single cell. Parent cell that is diploid begins the meiosis, this means Parent cell has 2 copies of each chromosome. This process gives four daughter cells that are haploid in nature, this means that they contain half the number of chromosomes of the parent cell.

So, the statement stated is false (B) as chromosome from each pair in a diploid cell are not randomly assorted in to a new cell they are assorted half the number of chromosomes of the parent cell.

Answer 15: Mitosis- A process by which organisms produces new cells by cell division mechanism. In this process a parent cell is divided to produce two identical daughter cells. This process includes the division of genetic material (DNA) by the method called cell duplication in which nucleus division also takes place.

Purpose of mitosis in animals:

To produce two identical daughter cells that is the copy of parent cell

To pass proper number of chromosome to the next generation

To replace damaged tissues

To make more diploid cells

To maintain growth in animals

To replace old cells like in RBCs which lives for only four months

To replace finger nails and hairs

In replacement of body parts like in star fish
