Relation with Chemistry:
- Body of all living organisms s made up of organic and inorganic compounds.
- All the metabolic activities inside the body of living beings involve chemical reactions and chemical changes.
- Genetic materials DNA and RNA are also chemicals.
- Enzymes and hormones produced in the body of living organisms are also exclusively chemicals.
- Acid-base equilibrium in a cell maintains the pH of the protoplasm for proper functioning.
- Molecules move in and out of the cells by diffusion and osmosis.
Relation with Physics:
- Biological instruments such as microscopes, X-rays, ECG etc. are based on the principles of physics.
- Light induces various effects on living organisms.
- Study on the structure and functioning of human eye require knowledge of optics.
- Physical techniques such as: electron microscopy, X-ray diffraction, fractionation, Chromatography etc. have made possible the study of finer details of cellular and sub-cellular components.
Relation with Geography:
Distribution of plants and animals vary different geographical factors. e.g. Climate, altitude, temperature, etc.
Relation with Mathematics and Statistics:
Census of wild animals is based on application of mathematical and statistical applications. Such applications are helpful in data compilation and analysis of living organisms.
Relation with Sociology:
