homeostasis

Which is NOT a characteristic/example of positive feedback?

• Body temperature and blood glucose levels

• Blood clot formation

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
