Answer:
B. Regulated variables, set-point
Explanation:
Regulated variables also called a sensed variable. It is a regulatory mechanism in the body which is called homeostasis. Constancy in the internal environment of the body is explicit and in a concrete way. Homeostasis is a mechanism to regulated variables, in an internal environment within a range in which life is comfortable. To emphasize the sustained process of the mechanism, we distinguish between the regulated (sensed) and non-regulated (controlled) variables.
Set-point:
The set-point varies from person to person. so it's not a good idea to go for a diet chart. the amount of fat in the body is called adipose. although it may go down and upward from time to time. the body fat, most people carry is relatively stable and maintained which is called a set point.
