Nerve impulses are carried to another part of the body by a neuron’s: (1) dendrites
(2) axon
(3) synapse
(4) neurotransmitter

1.

Explanation:

Dendrites is the neuron's that receives nerve impulses and carry it to another part of the body.

Nerve impulses are the messages that are transferred from one part of the body to the another. These messages are carried across the body with the help of neuron's named  dendrites.

Dendrites are branched like projections of in the nerve cell. Through these projections, message passes across the body.  

Therefore, option 1 is correct.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.
