Question
Chapter 39.4, Problem 2R
Summary Introduction
To review:
The reason that determines whether the animal has lost or gained heat in each heat exchange pathway.
Introduction:
There are various heat exchange mechanisms between the body of an organism and its environment. This heat exchange takes place either through conduction, convection, radiation, or eavoration. An animal either gains heat or loses it, which depends on its internal as well as the external environment.
