- Which of the following statements is true regarding the impact of the environment on snake behavior? In wet climates, a snake is more active because it does not lose as much heat via evaporation. In hot weather, a snake is more active because it can gain body heat by conduction. In cold weather, a snake is less active because the food supply is decreased. In dry climates, a snake is less active because there is less moisture in the air.Label the GI Anatomy of a dogState TWO ways how the gigantic ears of the elephants help in thermoregulation.
