The correct option is C. Motor neuron does not fire action potentials
Explanation:
During contraction, the motor nerve passes down an action potential. A neuromuscular junction is formed by the motor neuron which stimulates the entry of calcium ions. The calcium ions bind to structures called as troponin which stimulates the binding of the filaments, actin and myosin. The filaments begin to contract by using ATP.
During relaxation, the action potential is stopped. Calcium is taken back into the sarcoplasmic reticulum. As a result, actin and myosin filaments do not link and hence, the contraction is stopped.
As a real world application, this can be beneficial in the process in which a farmer would grow their plants. If they would the process that provided the healthiest, biggest plants, they would choose that to fertilize with.
I would say C. eliminating government funding of research. without finding, scientists can't experiment, therefore all their research remains purely theoretical and isn't considered a discovery.
