Important Questions on Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.

EASY
Life Sciences>From Molecules to Organisms: Structures and Processes>Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.>Structure and Function - Feedback mechanisms maintain a living system’s internal conditions within certain limits and mediate behaviors, allowing it to remain alive and functional even as external conditions change within some range. Feedback mechanisms can encourage (through positive feedback) or discourage (negative feedback) what is going on inside the living system
