B)Neurons are composed of groups of nerves.
C)They act as pipes in the body,transporting fluid.
D)Signals generated in nerves can travel only short distances.

Accepted Answer

Nerves are composed of groups of neurons, not vice versa. Neurons are the basic functional unit of the nervous system and nerves are formed by groups of neurons bundled together to transmit signals to and from various parts of the body. Nerves do not transport fluid and signals generated in nerves can travel long distances along their length.
