What happens when a nerve impulse reaches the end of a neuron? A. Neurotransmitters are released and bind to receptors on the next
neuron, causing potassium ions to move into the neuron.
B. Potassium ions are pumped into the synapse, creating an action
potential at the next neuron.
C. The nerve impulse stops.
D. Potassium ions cause the synapse to close, allowing the impulse
to pass directly to the next neuron.

A, the answer is A.

Explanation:

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. The binding allows the nerve impulse to travel through the receiving neuron.

Hope this helps! :D

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.
