Question

Quizplus · Accepted Answer

When the surrounding temperature is low, heat is lost from the body by means of radiation and conduction/convection. Radiation is the transfer of heat through electromagnetic waves, while conduction/convection is the transfer of heat through direct contact with a colder material (such as air or water). Nonshivering thermogenesis is a way the body generates heat without shivering but is not a factor in heat loss. Therefore, D is the best choice as it includes both means of heat loss in this situation.
