Category : Research Topics,

Biology is the scientific study of life and living beings. In this, a student studies physiology, morphology, anatomy, behavior, and other qualities of a living organism. Biology is derived from the Greek words “bios” and “logos”. Bios mean life; logos means study. 

Biology is an essential branch of science and the most crucial branch in itself, the medical science emerged parallelly with biology. Today we are aware of the human body parts and the diseases related to them and the cure to the disease, this is all because of biology. Hence, biology is the most helpful branch of science for living beings.

This field of science could be enhanced by the new generation as they perform research for the sake of humanity and for the betterment of medical science so that, in the future, all living beings can live a disease-free life.
