For each statement below, identify which major theme is evident (the relationship of structure to function, information flow, pathways that transform energy and matter, interactions within biological systems, or evolution) and explain how the statement relates to the theme. If necessary, review the themes (Chapter 1 ) and review the examples highlighted in blue in this chapter.The ability of your body to respond to environmental changes depends upon the interplay of the endocrine and nervous systems.

Step by Step Solution: Step 1. Identify the major theme that the statement pertains to. Step 2. Explain how the statement relates to the identified theme. Step 3. The major theme that the statement pertains to is interactions within biological systems. Step 4. The statement explains how the endocrine and nervous systems interact with each other to enable the body to respond to changes in the environment. This interplay between the two systems is critical to maintaining homeostasis in the body. The nervous system receives sensory input from the environment and sends signals to the endocrine system. The endocrine system then releases hormones that coordinate the body's response to the environmental changes, such as increasing heart rate in response to stress. Step 5. The final answer is that the statement relates to the major theme of interactions within biological systems. Final Answer: interactions within biological systems
