Runners sprinting short distances in a relay race and handing off a baton scenario best exemplify the way a signal is passed down an axon coated with a myelin sheath.
Axons are long extensions of neurons (or nerve cells) involved in the transmission of nerve impulses away from the cell body. Each nerve cell has an axon that is over a foot long. A nerve cell communicates with another nerve cell by transmitting signals from the branches at the ends of the axon.
Each neuron in the brain has long cables that meander from the body of the cell. These cables, several times thinner than human hair, are called axons and are where electrical impulses leave neurons and are received by other neurons.

The correct answer attached in file, Thank you for joining brainly community.
Answer:
can only be determined experimentally.
Explanation:
In the early days of inorganic chemistry, the structure of complex ions remained a mystery hence the name ''complex''.
These ions appear to have structures that defied accurate elucidation. However, by diligent laboratory investigation, Alfred Werner was able to accurately determine the structure of cobalt complexes. As a result of this, he is regarded as a pathfinder in coordination chemistry.
Hence, the structure of complex ions can only be determined experimentally.
