Bio-technology is the branch of biology that deals with the use of data and techniques of engineering and technology concerning living organisms. This field combines the principles of biology and technology to develop new products and processes that have practical applications in medicine, agriculture, industry, and environmental science. Bio-technology encompasses a wide range of techniques, including genetic engineering, recombinant DNA technology, bioremediation, and tissue engineering.

A. Human Biology is the study of the structure, function, and development of the human body and how it responds to its environment.

B. Environmental Biology is the study of the relationship between living organisms and their environment, including the effects of human activities on the natural world.

C. Genetics is the study of inheritance, including how traits are passed from one generation to the next and how genetic information is stored, expressed, and regulated in cells.
