Which level of organization is represented by a group of different tissues working together to perform a complex function?

• cell
• tissue
• organ
• organism

All the organ systems of the human body work together to maintain homeostasis.  What is homeostasis?

• a stable internal environment
• response to external stimuli
• protection from bacteria and other pathogens
• the ability to pass characteristics to one's offspring

The hormones of the body help maintain homeostasis via negative feedback.  What happens in a negative feedback mechanisms?

• The body does not respond to a change in its environment.
• The body removes a stimulus prompting a response.
• A response to a change reverses the direction of the change.
• A response to a change increases the effect of the change.
