When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron.
Explanation:
The binding allows the nerve impulse to travel through the receiving neuron.
B. Independent meaning by itself. Dependent meaning together, or not by itself, and since both are going 60mph and they both stop it’s dependent because they’re depending on each other to stop.
