Answer:

During the creation of oocyte, 3 additional haploid cells are created that will not be fertilized these cells are called Polar bodies.

Explanation:

The process of formation of oocyte is known as the Oogenesis. The oogenesis is the formation of oocyte which is capable of being fertilized, and the process begins even before the birth of the child. The oogonia is a diploid cell which undergoes mitosis to form the primary oocyte.

The primary oocyte then undergoes first meiotic division forming the secondary oocyte. this secondary oocyte is haploid in nature and this would again undergo another meiotic division to produce 4 haploid daughter cells. One of these is haploid ovum with additional 3 cells which do not get fertilized. these additional haploid daughter oocyte cells are Polar bodies.

The feature of endocrine system that makes it distinctly different from the nervous system is that it uses hormones distributed through the bloodstream, option(A).

<h3>Why is endocrine system distinctly different from nervous system?</h3>
  • The biggest difference between these two is that the endocrine system uses hormones produced by glands into the bloodstream, whereas the nervous system uses electrical impulses to send signals through neurons.
  • The signal transmission of the nervous system is fast because neurons are interconnected, but the functions are short-lived when compared to endocrine system.

Therefore, option(A) is the correct answer.
