Question

Explanation:

All life - as we know it - requires water for various biological processes such as metabolism, transport of nutrients, and maintaining cell structure. While life is known to exist on Earth, we cannot be certain that life does not exist elsewhere in the universe. All life forms are interconnected and share a common ancestor, but this is a more evolutionary - related statement. Also, all life forms interact with their environment and other organisms in some way. Water is a universal requirement for life as we understand it.

Answer:

They all require water
