Water - The Essential Substance

Questions: 20 | Attempts: 358 | Last updated: Mar 21, 2025

Sample Question
Water is a simple chemical compound, each molecule composed of one oxygen and two ____________ atoms. Why, then, is it so important? Most fundamentally, water is essential for life. Every living organism on earth must have water in some form in order to survive. Every living cell is composed primarily of water. When space probes are dispatched to other planets in search of other life forms, they look for the presence to water to determine if life, as we know it, is possible there.
