Give reason that there are limitation to the use of electric impulses.

When messages are transmitted through electric impulses, they reach various cells rapidly but are not able to reach every cell of the body.

The effect of electrical impulse also lasts for a shorter duration.

In contrary to this, chemical communication is carried out through hormones, and the information is transmitted throughout the body by the blood.

As the information is carried through blood, it reaches every cell of the body, allowing them to communicate with each other, and thus, the effect lasts for a longer duration and maintains a steady rate.

Therefore, in multi-cellular organisms, chemical communication is better than electrical impulses as a means of communication between cells.
