Answer:
Meiosis.

Meiosis may be defined as the process of cell division in which a single parent cell divides into four daughter cells. This type of division occurs in the sex cells.
The meiosis division is also known as reduction division because the daughter cells contain the half number of chromosomes as compared with parent cell. The meiosis is divided into meiosis-I and meiosis-II.
Thus, the correct answer is option (C).
Answer:
They are necessary for co-ordination.
Explanation:
The both systems brings about co-ordination, thought there are some basic differences between them. Many organs in an animals system have organs to carry out activities like locomotion, digestion, respiration and excretion. The activities of each organ system must be co-ordinated with those of other systems; and with conditions in the external and internal environments of the animal.
