What is meiosis?

The division of gametic or sex cells is known as meiosis. The process of reproduction involves this. It takes eight phases to finish. It is split into two sections. The first and second meiosis.

In the chromosomes in meiosis 1 a full set of chromosomes is present and in meiosis 2, the number is diploid (2N).

Therefore, the correct option is D,Chromosomes have two chromatids at the end of meiosis I and one chromatid at the end of meiosis II.

Homeostasis is maintained by a series of control mechanisms functioning at the organ, tissue or cellular level. These control mechanisms include substrate supply, activation or inhibition of individual enzymes and receptors, synthesis and degradation of enzymes, and compartmentalization. For example, to regulate temperature, you will sweat when you get too hot or shiver when you get too cold.
