Detailed explanation-1: -If an organism has a diploid number of 10 it has 10 chromosomes-5 homologous pairs. It will therefore 20 chromatids, all of which will be present in prophase. Mitosis creates two diploid daughter cells from a diploid mother cell.

Detailed explanation-2: -If a nucleus has ten chromosomes after replication, the cell will have only five chromatids. This is because each chromatid is made up of a pair of replicated chromosomes, which exist as sister chromatids during prophase and metaphase stages of the cell cycle.

Detailed explanation-3: -During metaphase, there are 46 chromosomes composed of two sister chromatids each that align at the metaphase plate. Then, during anaphase, these chromatids are separated and pulled to opposite poles of the cell. This separation results in 92 separate chromatids in the cell, which are considered 92 chromosomes.

Detailed explanation-4: -The microtubules of the mitotic spindles are attached to it. Therefore, a cell having 20 centromeres will have 20 chromosomes.

Detailed explanation-5: -For a cell with a diploid number of 10 (2n = 10), the two daughter cells that are produced after mitosis will contain ten chromosomes (identical to the parental cell).
