A sensor/receptor is required to monitor and limit levels. 2. A sensor/receptor is unnecessary to monitor and limit levels. 3. Feedback prevents homeostasis. 4. Feedback contributes to homeostasis. 5. Feedback stimulates the effector to continue to do the same thing. 6. Feedback stops the effector from doing one thing and stimulates it to do the opposite. 7. When the target level for a hormone is reached, feedback results in a reduction of that hormone being released. 8. When a target level for a hormone is reached, feedback results in an increase of that hormone being released. Record your answers in ascending (lowest to highest) order.arrow_forward
