Explanation:
For the body to maintain stable conditions for optimal working of biochemical activities in cells, then it will require to constantly readjust any imbalances and offshoots that occur (which is the case regularly) through a positive and negative feedback mechanism. An example is blood sugar. After food intake, the blood sugars tend to rise a bit and the body produces more insulin to communicate to the cells to take up the excess glucose from the blood and store it. During starvation when the blood sugar tends to drop below normal levels, the level of insulin is reduced and that of glucagon is heightened. This causes the stored glucose to be released into the blood to restore homeostatic levels. This kind of balancing act happens with many other variables in the body.
