Introduction What is Biology? What is life? Is Biology a science? What is the difference between science and technology?

Scientific process Discovery based science: describing nature. Hypothesis based science: explaining nature. The word science is derived from a Latin verb meaning “to know”. Science seeks natural causes for natural phenomena. Thus the scope of science is limited to the study of structure and processes that we can observe and measure, either directly or with the aid of tools.

Discovery Science : Verifiable observations and measurements are the data of discovery science. In biology, discovery science describes life at its many levels, from the biosphere down to the molecules in cells. Examples of discovery science are: • sequencing of the human genome. • arrangements of cells in the small intestine. Inductive reasoning is the type of logic used in discovery science, which is based on general principles derived from a large number of specific observations. For example, every biological specimen observed is made up of cells, therefore “all organisms are made of cells”.
