STANDARDS 2 -A 2 -B • A. . Identify and describe the relevant parts and functions of at least two major organ systems. 1. Describe how the organ systems impact each other and the overall system. • B. Describe feedback mechanisms which maintain homeostasis in response to environmental change. 2. . Conduct and analyze an investigation to explore the relationships between feedback mechanisms and homeostasis within an organism.

RECOGNIZE OR RECALL SPECIFIC VOCABULARY SUCH AS: • Homeostasis, Negative Feedback Mechanism, Positive Feedback Mechanism, Respiratory System, Circulatory System
