Final answer:
Metabolism refers to the chemical processes that occur within a living organism to maintain life. c)Metabolism will always result in a net gain of heat by the body.
The correct answer is C.
Step-by-step explanation:
In the context of the human body, metabolism involves various reactions that break down nutrients to provide energy and build molecules essential for cellular function. These metabolic processes release energy, and this energy contributes to the heat production in the body.
Conductance, convection, and radiation are all modes of heat transfer rather than sources of heat production. They describe how heat is transferred between the body and its surroundings:
a) Conductance involves the transfer of heat through direct contact with a material.
b) Convection involves the transfer of heat through the movement of fluids (liquids or gases).
d) Radiation involves the emission of electromagnetic waves.
While these modes of heat transfer can affect the body's heat balance, they don't necessarily result in a net gain of heat by the body. Heat gained or lost depends on factors like the temperature gradient between the body and its surroundings. On the other hand, metabolism is a constant source of heat production within the body.
The complete question is:
Which of the choices below will always result in a net gain of heat by the body?
a)Conductance
b)Convection
c)Metabolism
d)Radiation
