Biology is a
natural science concerned with the study of
life and living
organisms, including their structure, function, growth,
evolution, distribution, and
taxonomy. Modern biology is a vast and eclectic field, composed of many branches and subdisciplines. However, despite the broad scope of biology, there are certain general and unifying concepts within it that govern all study and research, consolidating it into single, coherent fields. In general, biology recognizes the
cell as the basic unit of life,
genes as the basic unit of
heredity, and
evolution as the engine that propels the synthesis and creation of new
species. It is also understood today that all organisms survive by consuming and transforming
energy and by
regulating their internal environment to maintain a stable and vital condition.
