Chapter 20, Problem 12TYK

Summary Introduction

To describe: The reason why the driver maintains a constant speed of 55 miles per hour while driving a car over a hilly terrain with reference to the concept of homeostasis.

Introduction: Homeostasis is a self-regulatory process; it is the tendency of an organism to seek and maintain the internal environment in response to external changes by maintenance of equilibrium and stability in the body or a system. The negative feedback mechanism of homeostasis reverses the unstable condition back to the normal condition and restores the stability or equilibrium. For example: When the salt concentration of blood goes up, the kidneys expel more salt.
