which is one way that water helps living things?\no temperature regulation\no oxygen transportation\no heat…

Answer:

A. temperature regulation

Brief Explanations:

Water has a high - specific heat capacity, which allows it to absorb and release a large amount of heat without a large change in its own temperature. This property helps living things regulate their body temperature. Oxygen transportation is mainly related to blood and respiratory systems, heat absorption is a part of temperature - regulation but not the most comprehensive answer here, and water is not directly involved in nutrient production.
