Biology - Neural Control and Coordination Question with Solution | TestHub

The rate of transmission of nerve impulses is directly proportional to the body temperature.

Whale is a mammal and a homeotherm (warm-blooded animal), which maintains a constant and relatively high body temperature.

Labeo (fish), Salamander (amphibian), and Tortoise (reptile) are poikilotherms (cold-blooded animals) whose body temperature fluctuates with the environment and is generally lower than that of homeotherms.

Due to the higher and constant body temperature, the rate of transmission of nerve impulses is comparatively higher in whales.

Answer: Whale
