a desire to perform behavior in return for rewards.
B
a rigidly patterned behavior characteristic of entire species.
C
an aroused or activated state that is often triggered by physiological need.
D
the body’s tendency to maintain a constant/balanced internal state.
Explanation: 

Detailed explanation-1: -The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose.

Detailed explanation-2: -In short, the purpose of homeostasis is to maintain the established internal environment without being overcome by external stimuli that exist to disrupt the balance.

Detailed explanation-3: -(HOH-mee-oh-STAY-sis) A state of balance among all the body systems needed for the body to survive and function correctly.

Detailed explanation-4: -The body maintains homeostasis by controlling a host of variables ranging from body temperature, blood pH, blood glucose levels to fluid balance, sodium, potassium and calcium ion concentrations.

Detailed explanation-5: -it IS accurate to define homeostasis as a constant internal environment. While homeostasis is dynamic the range in which homeostasis maintains the body is relatively constant. This is because an organism must have a stable internal environment otherwise cell damage or death may occur.
