Final answer:
Water's high specific heat helps organisms maintain a steady internal body temperature and supports homeostasis by absorbing and releasing heat slowly.
Step-by-step explanation:
Water's high specific heat allows organisms to maintain a steady internal body temperature by absorbing and releasing heat slowly. This helps in maintaining homeostasis, which is the ability of an organism to maintain stable internal conditions despite changes in the environment. For example, in humans, when the external temperature rises, water in the body absorbs excess heat, preventing a rapid increase in body temperature. The body then uses mechanisms such as sweating to release heat and maintain a constant internal temperature.
