As far as we know all forms of life on Earth use ____________ as a medium for chemical reactions.

Question

Quizplus · Accepted Answer

Liquid water is the medium for chemical reactions in all known forms of life on Earth. It is a key component in biological processes such as metabolism and cellular respiration. Gaseous helium and frozen carbon dioxide are not suitable for supporting life as they do not provide the necessary sustenance for biochemical reactions. Frozen water, or ice, can hinder these reactions and is also not a medium for life in its solid state.
