True or False Blood clotting and uterine contractions are good examples of negative feedback.

• True
• False

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

If the environment gets cold, we will often shiver in order to:

• keep body temperature the same as the external temperature
• decrease body temperature
• increase body temperature
• regulate blood pressure

Homeostasis in the human body is often maintained by a: 

• neutral feedback loop 
• solar feedback loop
• positive feedback loop
• negative feedback loop
