Electrical impulses are an excellent means of quick transfer of information in animals but there are limitations to the use of electrical impulses.
Electrical impulses are an excellent means of quick transfer of information in animals but there are limitations to the use of electrical impulses. List such two limitations. State the other means of communication used by most multi-cellular organisms between the cells.

Two limitations are :
(i) They reach only those cells that are connected by nervous tissue and not each and every cell in the animal body.
(ii) Once an electrical impulse is generated in a cell and transmitted, the cell will take some time to reset its mechanisms before it can generate and transmit the electrical impulse.
Other means of communication is chemical communication or chemical co-ordination by compounds called hormones.
