True or false, the human body has only one mechanism for preserving a state of constant internal conditions.?

Answer 1

True, it's called your brain.

Answer 2

3. Homeostasis is the maintenance of relatively constant conditions within the body's internal environment. Many physiological parameters, such as blood glucose and body temperature, are precisely regulated by a homeostatic mechanism. Regulation of a physiological event usually occurs via a feedback mechanism. Negative feedback is more common and is the response of the system in a direction opposite to the change that set it in motion. The end result of negative feedback is to bring a deviation in a physiological event back into line. Conversely, positive feedback is a response which further enhances the change that set it in motion.
