Which outcome occurs when a mammal's body temperature drops sharply during cold exposure?

💡 Explanation

When body temperature declines, shivering thermogenesis is triggered via muscle contractions because hypothalamic thermoreceptors detect the drop in core temperature, generating metabolic heat. Therefore metabolic heat increases via shivering, rather than reduced blood flow, lesser thermal gradient or elevated glucose changes, which represent different physiological and hormonal processes.
