Which effect promotes the dissipation of heat when environmental temperature rises in endotherms?

💡 Explanation

When external temperature increases, peripheral vasodilation occurs, increasing blood flow to the skin and stimulating conductive heat loss because this is how heat radiates into cooler environments; therefore, the animal cools its core, rather than upregulating other thermogenic processes.
