Does the graph show positive or negative feedback?

• Positive, because when the red line shifts, the blue one does also

• Negative, because the blue line starts below equilibrium

• Negative, because the two actions are keeping each other near equilibrium

• Both positive and negative because the graph moves up and down

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
