Answer: (E)

Verified step by step guidance

1. Identify the two systems that are responsible for coordinating and controlling physiological processes in animals. These systems are typically involved in communication and regulation within the body.
2. Understand the role of the nervous system: It is responsible for rapid communication and response to stimuli through electrical signals. It includes the brain, spinal cord, and nerves.
3. Understand the role of the endocrine system: It regulates slower, long-term processes through the release of hormones into the bloodstream. It includes glands such as the pituitary, thyroid, and adrenal glands.
4. Consider how these two systems interact: The nervous system can influence the endocrine system by signaling glands to release hormones, while hormones can affect nervous system activity.
5. Recognize that the nervous and endocrine systems work together to maintain homeostasis, coordinate growth, metabolism, and other vital functions in animals.
