Answer 2

Notochord is the skeletal rod that lies wise in length between the central nervous system and the food channel or intestine, and it is borne by the chordates at young developmental stage. For adult vertebrates it is replaced by the vertebral column. On the other side, a nerve cord is a solid nervous tissue filament that forms part of the invertebrate central nervous system in particular.

The key difference between the two is that notochord is a part of the skeletal system while nerve cord is a nervous system component.
