In biology, living organisms, including their structure, function, growth,
reproduction, classification, origin, and evolution are discussed. Biology
also teaches how to use this knowledge to improve human life. To discuss this
knowledge in detail, biology has been divided into two branches. One is
physical biology in which theoretical concepts are discussed, and the other is
applied biology in which the way of using theoretical knowledge is discussed.
Actually, for learning and using knowledge easily and effectively, biology is
divided into these two parts.
