Answer:
|
Water is required for all life on Earth because it is essential to cells and metabolic systems.
- Water is an extraordinarily versatile molecule. About two thirds of the mass of a cell is made up of water, and most of the biochemical processes of life occur in water solutions.
- Water is the perfect liquid medium in which to dissolve nutrients for ingestion or wastes for excretion, to transport important chemicals or even be used as one.
- The solid form of water, ice, floats, preventing lakes and oceans from freezing solid.
