Question

Most processes in the body are controlled by negative feedback. If a homeostatic system is controlled by this, the resulting action will always be in the opposite direction of the stimulus. In this way the variable is maintained with a normal level, or set point. The variable ____________ constant over time and this ____________ occurs around the set point. If the stimulus increases, the homeostatic system is activated to cause a ____________ in the stimulus. In contrast, if the stimulus decreases, the homeostatic system causes a(n) ____________ in the stimulus until it returns to normal.

Answer 1

Answer:

Most processes in the body are controlled by negative feedback. If a homeostatic system is controlled by negative feedback, the resulting action will always be in the opposite direction of the stimulus. In this way, the variable is maintained within a normal level, or what is called its set point.

The variable does not remain constant over time and this fluctuation occurs around the set point. If the stimulus increases, the homeostatic system is activated to cause a decrease in the stimulus. In contrast, if the stimulus decreases, the homeostatic system causes a(n) increase in the stimulus until it returns to normal.
