Final answer:
Water's high specific heat allows it to regulate temperature in cells, moderate temperature changes in coastal areas, and help warm-blooded animals maintain a stable internal temperature.
Step-by-step explanation:
Water's specific heat capacity is related to its usefulness for life because it takes a lot of energy to raise or lower the temperature of water. This property helps to maintain temperature regulation in cells, which is important for maintaining homeostasis.
Water's high specific heat also allows it to act as a heat sink or reservoir, absorbing and releasing heat slowly. This property helps to moderate temperature changes in coastal areas, preventing extreme fluctuations in environmental temperature.
Additionally, water's high specific heat is used by warm-blooded animals to evenly disperse heat in their bodies, helping them maintain a stable internal temperature.
