Select the statements that correctly describe positive feedback pathways.
A sensor/receptor is required to monitor and limit levels. A sensor/receptor is unnecessary to monitor and limit levels. Feedback prevents homeostasis. Feedback contributes to homeostasis. Feedback stimulates the effector to continue to do the same thing. Feedback stops the effector from doing one thing and stimulates it to do the opposite. When the target level for a hormone is reached, feedback results in a reduction of that hormone being released. When a target level for a hormone is reached, feedback results in an increase of that hormone being released.

Neurotransmitters are released into the synaptic cleft. Neurotransmitters bind to ion channels. Sodium ions enter into the dendrites. Neurotransmitters are returned to the axon terminal, broken down by the enzymes or diffused away from the synapse. Action potential arrives in axon terminal. Synaptic vesicles containing the neurotransmitters fuse with the presynaptic membrane. Ion channels open.
The sequence in which the events numbered above are involved in the signal transmission across the synapse is
