Applications Of Biology For The Welfare Of Mankind

The practical contributions of biology to civilization have made most people aware of its importance. Knowledge of biology ensures a higher standard of living. It helps people to participate intelligently in programs designed to promote better health. Protection and conservation of environment, application of modern techniques in the field of agriculture and medical sciences etc.

Biological Methods

The methods to tackle problems in the field of biology work almost on the same principles as in any other field of science. Biologists work out the topics and recognize them as problems to be solved. Scientists make keen observations and collect the facts already reported by others. On the basis of these facts, a scientist formulates a tentative statement, called hypothesis. This hypothesis is used of guide further observations and experimentation. This part of the scientific method involves inductive reasoning. In this, a scientist uses isolated facts to reach a general idea that explains a phenomenon. For example, Robert Hooke observed, a thin slice of cork being composed of units, which he called Cells. This led of further observations and experimentation on plant animal material, by M.J Schleiden and T.Schwann, who proposed the cell theory, stating that all forms of life are up of cells.

Biology And Its Major Fields

Biology is one of the natural sciences, which deals with the things that exhibit the properties of life. Scientist calls these things as "organism". The word biology has been derived from Greek words Bios, life + Logos, discourse, Formerly living organism were classified into two kingdoms i.e plant kingdoms and animal kingdom. The plants were studied under the subdivision BOTANY and the animals were studied under the subdivision Zoology. The latest research has discarded the old concept of two kingdoms of living organism.

The Biology

The biology recalls your previous exposure to biology in early classes. It gives you some novel thoughts of thinking about living things beginning from the molecular levels up to the level of complex organisms. It provides you the basis for systematic observations. Hypotheses, Predictions and experimentation. Finally, this chapter gives you few examples of the endeavors like modern diagnostic, therapeutics control of diseases and techniques like cloning, hydroponics etc, of a number of brilliant biologists.
