Final answer:
Water is important for life because it is crucial for biochemical reactions and helps regulate temperature in organisms.
Step-by-step explanation:
Water is important for life due to its critical role in cellular processes and the fact that most organisms contain significant amounts of water. Firstly, water is necessary for many biochemical reactions to occur in living organisms. It acts as a solvent, facilitating the transport of nutrients, waste, and other molecules within cells. Secondly, water helps to maintain temperature homeostasis in organisms.
It has a high specific heat capacity, meaning that it can absorb and release a large amount of heat energy without significantly changing its own temperature. This property allows water to regulate the internal temperature of organisms and protect them from temperature fluctuations in their environment.
