Homeostasis is a state of balance inside the body, where the body systems work together to keep it functioning normally. The endocrine system keeps this internal balancing act going by releasing chemicals called hormones. The release of the hormones is controlled by negative feedback mechanisms.
A negative feedback mechanism works something like a thermostat in your home. A thermostat helps maintain a constant temperature, called the normal range. When the temperature rises beyond the normal range, the thermostat turns on the air conditioner. Eventually the air conditioner restores the temperature to the normal range. This process is called negative feedback. It starts with a normal range, goes beyond the normal range, and then back to normal again.
An example of how negative feedback works in the body can be demonstrated by the endocrine system's controls over the amount of sugar in the bloodstream. Insulin is a hormone secreted by the pancreas that maintains a normal amount of sugar in the bloodstream. Shortly after eating a candy bar, tiny sugar molecules enter the bloodstream raising the blood sugar levels. In response, the pancreas secretes the insulin into the bloodstream. Now, the sugar molecules move out of the bloodstream and into the cells of the skeletal muscles, fat and liver. In turn, the blood sugar levels return to normal.

Regulatory homeostasis
The ability of an organism to maintain internal stability is known as homeostasis.

No. Maintaining homeostasis is a characteristic of living things.
All organisms exhibit homeostasis.

Regulatory homeostasis
effects of homeostasis?
Neither. Homeostasis is a noun. Homeostatic is the adjective associated with homeostasis.
The ability of an organism to maintain internal stability is known as homeostasis.
The stabilization of body temperature is homeostasis. What affects homeostasis is the interaction of the hypothalamus and hormones, such as prostaglandin; an indirect marker for inflammation. Homeostasis is constant/stable. The hypothalamus ensures body temperature homeostasis.
The word nomeostasis rhymes with homeostasis.
if homeostasis is not maintained, the cell explodes.

No. Maintaining homeostasis is a characteristic of living things.
This is called homeostasis.
