Homeostasis

• allows for a wildly fluctuating internal environment
• is impossible in vertebrates
• is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation
• is the maintenance of a relatively stable external environment and often incorporates a form of feedback regulation

• decrease body temperature
• increase body temperature
• regulate blood pressure

The "cause" for something to happen is the

• response
• effect
• stimulus
• homeostasis

Most bacteria that cause sickness in humans grow best at 98.6^oF. Sometimes a fever is the body's response to the bacteria. What is the reason for developing a fever?

• To lower the temperature of the body to kill the bacteria
• The increase the temperature of the body to kill the bacteria
• To allow the bacteria to take over
• To make you feel miserable
