-Because of Homeostatic imbalance as we age our body organs become less efficient, and our internal conditions become less and less stable. This event has a risk for illness and produce changes we associate with aging.
Explanation;
-Homeostasis is the body's ability to maintain a relatively stable internal environment even though the outside world is constantly changing. It involves both positive feedback Loops and the negative Feedback loops.
-Aging is a general example of disease as a result of homeostatic imbalance. As an organism ages, weakening of feedback loops gradually results in an unstable internal environment. This lack of homeostasis increases the risk for illness and is responsible for the physical changes associated with aging.
Such plants are called vascular plants.
