The knowledge of biology has greatly helped us in the field of human health. Therefore helps us to understand the cause of many diseases. We are able to identify various micro-organisms that cause diseases in man. Hence We can study their mode of living and the different ways in which they spread diseases. Therefore understanding of disease-causing microorganisms has led to the development of new drugs, both natural and synthetic drugs that can kill these organisms.
