Homeostasis is

• The process by which organisms maintain a relatively stable internal environment
• The process by which organisms change their internal environment
• The process by which organisms adapt to their external environment
• The process by which organisms evolve over time

A Negative Feedback Loop is...

• A process that reinforces a system's output
• A process that counteracts a system's output
• A process that has no effect on a system's output
• A process that amplifies a system's output

A Positive Feedback loop is...

• A system where the output enhances the original stimulus
• A system where the output suppresses the original stimulus
• A system where the output has no effect on the original stimulus
• A system where the output reverses the original stimulus

During Homeostasis...

• The sensor sends a message to the effector

• The effector sends a message to the control center

• The sensor sends a message to the control center

• The control center sends a message to the sensor

In homeostasis the control center

• Sends a message to the effector
