Answer:
20 chromosomes
Explanation:
Mitosis is a kind of cell division that results in daughter cells with same number of chromosomes as the parent cell. It involves stages including Prophase, Metaphase, Anaphase and Telophase. In prophase, the Chromatin condenses into Chromosomes.
In Anaphase stage, the 10 chromosomes as mentioned in the question divides into opposite poles of the cell. One individual chromosome contains two sister chromatids, which actually separates in the Anaphase stage. Hence, at the end of the Anaphase stage, there will be 10 chromatids each at opposite poles of the cell. Each chromatid at this stage is considered a chromosome.
Hence, a cell with 10 chromosomes will contain 20 chromosomes (10+10 chromatids on each pole) in the Anaphase stage just before the cell divides into two in a process called CYTOKINESIS.
What Happens during Prometaphase? When prophase is complete, the cell enters prometaphase — the second stage of mitosis. During prometaphase, phosphorylation of nuclear lamins by M-CDK causes the nuclear membrane to break down into numerous small vesicles.
The correct answers are A and C.
When an individual is reproducing asexually, it means that there is no fusing of two parent cells and meiosis, but that the offspring is produced out of the cells of one parent. This means that the organism is not '' losing time'' by trying to find a suitable mate, which enables the populations to grow at a rapid rate.
However, the offspring are genetically identical to the parent, which means that there is very little genetic variation in the population which can lead to accumulation of harmful mutations and unresponsiveness to changes in the environment.
