Question

Positive-feedback control systems:

A)have no effect on the deviation from set point.
B)accelerate a change.
C)ignore a change.
D)do not exist in human systems.

Answer 1

Positive-feedback control systems intensify changes in the body and are exemplified by processes like blood clotting and childbirth.

Step-by-step explanation:

Positive-feedback control systems are mechanisms that intensify a change in the body's physiological conditions, moving the system farther away from its normal range. Unlike negative feedback, which serves to bring a system back to its set point, positive feedback accelerates a physiological process to completion. Examples of positive feedback processes in human systems include blood clotting and childbirth, both of which are normal and only activate when needed to complete a specific physiological task.
