Select the statements that correctly describe negative feedback pathways.
1. A sensor/receptor is required to monitor and limit levels.
2. A sensor/receptor is unnecessary to monitor and limit levels.
3. Feedback contributes to homeostasis.
4. Feedback prevents 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 an increase of that hormone being released.
8. When the target level for a hormone is reached, feedback results in a reduction of that hormone being released.
Record your answers in ascending (lowest to highest) order.

Group of answer choices These antibodies would target nAChRs for destruction leading to lower sodium influx in muscle cells. These antibodies would target nAChRs, changing their shape to allow calcium instead of sodium through. These antibodies would target nAChRs, changing their shape to allow only potassium through. These antibodies would target nAChRs aiding acetylcholine in its binding to receptors, leading to increased sodium influx in muscle cells. pick one answerarrow_forward
