Answer 1

Answer: (A), (B), (C), (D)

To maintain body temperature for terrestrial beings.

Human body constitutes 60%-70% of water. Everything in our body is transported from one part to the other in a dissolved form. Almost all the cellular processes take place in aqueous medium. In fact, all the reactions that take place within our body occur in the aqueous medium only. Hence, water is essential for life.
