Answer: Vestigial organ

Explanation:

Vestigial organs are those organs which were functional in ancestral organisms belonging to the same species but due to the course of evolution of body forms they become non-functional. They can be found in the body either in the same form as used to appear in the ancestors or in rudimentary or degenerated forms.

The human appendix is one of the examples of vestigial organs. It looks like a narrow tube which forms a link with a colon of the large intestine. It was functional in human herbivorous ancestors as it used to help in digestion of variety of vegetables and other plant products. The change of diet along with due course of evolution caused the appendix to become useless. But the appendix physical form remained the same in humans.

How does the hypothalamus monitor water in the body?
krek1111 [17]

Answer:

The correct answer will be option-C.

Explanation:

Hypothalamus is a part of the brain which controls many important functions of the body by producing hormones.

When the amount of water gets reduced in the blood, it leads to a change in the osmolarity which can be easily detected by the osmorecpetors present in the neurons of the hypothalamus.

In response, neurons secrete Anti-diuretic hormone in the blood which acts in the tubules of the kidney where they help in re-absorption of the water from the body.

Thus, Option-C is the correct answer.
