Under comfortable temperature, in a human Bbl6epute ofluH OTBeT: a. heat loss is the lowest b. heat production is carried out at a high level c. heat production does not carried out d. heat loss is carried out at a high I level

The correct answer is d. heat loss is carried out at a high level.<br /><br />At a comfortable temperature, the human body is able to maintain a stable internal temperature through a balance between heat production and heat loss. At this temperature, the body's heat production is not at its highest level, but the heat loss is carried out at a high level to prevent overheating. This is achieved through various physiological mechanisms such as sweating, vasodilation (widening of blood vessels), and increased blood flow to the skin.
