Which characteristic of blood makes it especially effective in temperature regulation? Low specific heat capacity High specific heat capacity High evaporative potential

High specific heat capacity.

Explanation:

Thermoregulation is the ability of an organism body to maintain it's internal temperature. It is an important aspect of homeostasis which is ability of an organism to maintain internal temperature not minding the surronding environment.

Blood have high specific heat capacity which help to maintain body temperature. Blood absorbs and distribute heat to the body, so as to maintain homeostasis. Blood vessels contracts when they react with outside environment.
