Answer: process by which organisms maintain a relatively stable
internal environment
◉ set point.
Answer: parameters must be contained (ex. body temp)
,* can fluctuate to an extent
◉ negative feedback.
Answer: regulates homeostasis
◉ positive feedback.
Answer: loops disrupt homeostasis + amplify stimulus
