Biology
Biology is the science of living things. It covers part of the natural sciences and the natural history of living beings. This word is coming from the Greek: bios “life” and logos, “speech”.
With life in many forms and at very different scales, biology extends from the molecular level, to that of the cell, then the organism, to the level of the population and the ecosystem.
Main branch of Biology studies
Biology is a branch of science that deals with living organisms and their vital processes. Biology encompasses diverse fields, for example botany, conservation, ecology, evolution, genetics, marine biology, medicine, microbiology, molecular biology, physiology and zoology.
