Question

Quizplus · Accepted Answer

Effectors are responsible for causing change in the internal environment. They are the final step in a regulatory pathway, receiving signals from the integrator and responding to restore homeostasis. Therefore, option D is the correct answer. The other options describe the roles or responses of the regulatory systems and feedback mechanisms, but do not specifically refer to effectors.
