Human beings are the most intelligent organism due to the capability of thinking and understanding. For human, study of science has dual purposes. Firstly, they gain scientific knowledge. Secondly, they apply the knowledge for human welfare. On the basis of practical application, scope of biology in context of Nepal can be discussed in the following points;
