Answer;
-High specific heat
Explanation;
Water's high heat capacity is a property caused by hydrogen bonding among water molecules. Water has a large heat capacity which helps limit changes in body temperature in a warm or a cold environment.
Water enables the body to release heat when ambient temperature is higher than body temperature An individual begins to sweat, and the evaporation of water from the skin surface cools the body very efficiently. As a result, water plays a very important role in temperature regulation.

The correct options are as follows:
1. Human skin color variation is primarily determined by the type and amount of melanin pigment in the skin.
2. Human skin color variation likely evolved in response to differences in the intensity of sunlight around the world.
3. Human skin color evolve recently in hominid evolution, once some population of human ancestor migrated out of Africa.
The color of human skin is primarily determine by melanin. The intensity of the sun in the climate where one is living also affect the type of skin color that will dominate in a geographical area.
