Answer:
High specific heat capacity.
Explanation:
The specific heat capacity of water is the quantity of heat energy needed to raise 1 kg of water by one degree.
The high specific heat capacity of water is due to high hydrogen bonds which holds water molecules together, preventing their free movements.Therefore, large amount of energy is needed to raise water temperature. The hydrogen bonds also enabled water to store energy.
This features of water makes, plasma resistant to fluctuations in body and environmental temperature, and allows biochemical reactions to occurs at relatively constant rate.
