Geology – The study about various aspects of earth, an interesting branch that deals with digging the past
Palaeontology – Similar to Geology, which deals with studying various objects that existed in the prehistoric period
Sub branches, a blend of physics, chemistry, and biology.
Bio-Chemistry – Organic Chemistry, study about various processes happening in living organisms
Bio-Physics – A pure blend of Physics and Biology, where the concepts and theories of Physics are applied in biological elements.
Biotechnology – A new branch of science emerged as a baby of Biology and Technology, which deals with exploring microorganisms for production of drugs, artificial hormones, etc.
