Biology is the scientific study of life. [ 1 ] [ 2 ] [ 3 ] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. [ 1 ] [ 2 ] [ 3 ] For instance, all organisms are made up of cells that process hereditary information encoded in genes , which can be transmitted to future ...
The history of biology traces the study of the living world from ancient to modern times. Although the concept of biology as a single coherent field arose in the 19th century, the biological sciences emerged from traditions of medicine and natural history reaching back to Ayurveda, ancient Egyptian medicine and the works of Aristotle, Theophrastus and Galen in the ancient Greco-Roman world.
Science is a strict systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the world. [1] [2] Modern science is typically divided into three major branches: [3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; the social sciences (e.g., economics, psychology, and sociology), which study ...
Biotechnology is a multidisciplinary field that involves the integration of natural sciences and engineering sciences in order to achieve the application of organisms and parts thereof for products and services. [ 1] The term biotechnology was first used by Károly Ereky in 1919 [ 2] to refer to the production of products from raw materials ...
Natural science is one of the branches of science concerned with the description, understanding and prediction of natural phenomena, based on empirical evidence from observation and experimentation. [ 1] Mechanisms such as peer review and repeatability of findings are used to try to ensure the validity of scientific advances.
Molecular biology / məˈlɛkjʊlər / is a branch of biology that seeks to understand the molecular basis of biological activity in and between cells, including biomolecular synthesis, modification, mechanisms, and interactions. [ 1][ 2][ 3] Though cells and other microscopic structures had been observed in living organisms as early as the ...
Biomedical sciences. A biochemist engaged in bench research. Biomedical sciences are a set of sciences applying portions of natural science or formal science, or both, to develop knowledge, interventions, or technology that are of use in healthcare or public health. [ 1] Such disciplines as medical microbiology, clinical virology, clinical ...
The legacy of Greek science in this era included substantial advances in factual knowledge due to empirical research (e.g., in zoology, botany, mineralogy, and astronomy), an awareness of the importance of certain scientific problems (e.g., the problem of change and its causes), and a recognition of the methodological significance of ...
