Life science

            Life science comprises the branches of science that involve the scientific study of living organisms, like plants, animals, and human beings. However, the study of behavior of organisms, such as practiced in ethology and psychology, is only included in as much as it involves a clearly biological aspect. While biology remains the centerpiece of life science, technological advances in molecular biology and biotechnology have led towards a more specialized and new, often interdisciplinary, fields.

Biology: It  is the branch of natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy. Biology is a vast subject containing many subdivisions, topics, and disciplines.

Zoology: It is the branch of biology that relates to the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct. The term is derived from Ancient Greek zoon, "animal" and logos, "knowledge".

Human Biology: Human biology is an interdisciplinary academic field of biology, biological anthropology, nutrition and medicine which focuses on humans; it is closely related to primate biology and a number of other fields.

Botany: Botany or plant biology is a branch of biology that involves the scientific study of plant life. It covers a wide range of scientific disciplines including structure, growth, reproduction, metabolism, development, diseases, chemical properties, and evolutionary relationships among taxonomic groups. Botany began with early human efforts to identify edible, medicinal and poisonous plants, making it one of the oldest sciences. Today botanists study over 550,000 species of living organisms.

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.

Microbiology: the study of microorganisms, including viruses, prokaryotes and simple eukaryotes.

Anatomy: the study of the structure and organization of living things.

Molecular Biology: the study of biology at a molecular level.

Physiology: the study of the mechanical, physical, and biochemical functions of living organisms.

Taxonomy: the science of classification of animals and plants.

Entomology: the study of insects.

Genetics: the science of genes, heredity, and the variation of organisms.

Neurology: the branch of medicine dealing with the nervous system and its disorders.

Medicine:  The science of diagnosing, treating, and preventing illness, disease, and injury.

Radiology: the branch of medicine dealing with the applications of radiant energy, including x-rays and radioisotopes.

Marine Biology: the study of animal and plant life within saltwater ecosystems.

Bacteriology: the study of bacteria in relation to disease.

Social sciences

            The social sciences are the fields of scholarship that study society. "Social science" is commonly used as an umbrella term to refer to a plurality of fields outside of the natural sciences. These include: anthropology, archaeology, business administration, communication, criminology, economics, education, government, linguistics, international relations, political science, psychology (especially social psychology), sociology and, in some contexts, geography, history and law.
