4.1 ELECTRICITY OBSERVED IN LIVING SYSTEMS

Electricity is essential for the survival of every one of us. From almost the times of conception, the life and growth of an animal is dependent on electrical energy. In its absence, vital functions would come to a halt, resulting in crippling or death of an individual. For example, the heart requires electricity to function. If it fails, it ...
