• C. water conducts heat very fast and thereby maintains the body temperature
• D. water is stored as energy in our body

Answer 1

Answer: (B)

water can dissolve a lot of substances

Out of the total body weight, about two-thirds is made up of water and it is important to have regular intake of water. This is because water can dissolve a lot of substances because of its chemical makeup. When atoms in the other molecules are attracted to the water molecule, the non-water molecule pulls itself apart, causing it to dissolve. Water can attract many kinds of atoms and so it can dissolve many substances.
