Distinguish between the following pair:
Nerve impulse and flow of electricity (transmission and speed)
उत्तर
Nerve Impulse | Flow electricity |
The sodium-potassium pump transmits nerve impulses across axons by polarising and depolarising Na+ ions. Nerve impulses move at a speed of 100 m/sec. | Electricity flows through wires as electrons move between two points with different potentials. Electricity is conducted through wires at a speed of 1,50,000 km/sec. |
