  2. Natural science - Wikipedia

    en.wikipedia.org/wiki/Natural_science

    Natural science can be divided into two main branches: life science and physical science. Life science is alternatively known as biology, and physical science is subdivided into branches: physics, chemistry, earth science, and astronomy. These branches of natural science may be further divided into more specialized branches (also known as fields).

  3. Science and technology studies - Wikipedia

    en.wikipedia.org/wiki/Science_and_technology_studies

    A communications artifact (Rugby Aerial Tuning Inductor) at the Science Museum, London, UK . Science and technology studies (STS) or science, technology, and society is an interdisciplinary field that examines the creation, development, and consequences of science and technology in their historical, cultural, and social contexts.

  4. Evolution of metal ions in biological systems - Wikipedia

    en.wikipedia.org/wiki/Evolution_of_Metal_Ions_in...

    The prebiotic chemistry of life had to be reductive in order to obtain, e.g. Carbon monoxide (CO) and Hydrogen cyanide (HCN) from existing CO 2 and N 2 in the atmosphere. CO and HCN were precursor molecules of the essential biomolecules, proteins, lipids, nucleotides and sugars. [4]

  5. Environmental chemistry - Wikipedia

    en.wikipedia.org/wiki/Environmental_chemistry

    Environmental chemistry involves first understanding how the uncontaminated environment works, which chemicals in what concentrations are present naturally, and with what effects. Without this it would be impossible to accurately study the effects humans have on the environment through the release of chemicals .

  6. Chemistry - Wikipedia

    en.wikipedia.org/wiki/Chemistry

    Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.

  7. Toxicity - Wikipedia

    en.wikipedia.org/wiki/Toxicity

    Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. [1] Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity).

  9. Chemical biology - Wikipedia

    en.wikipedia.org/wiki/Chemical_biology

    An overview of the different components included in the field of chemical biology. Chemical biology is a scientific discipline between the fields of chemistry and biology.The discipline involves the application of chemical techniques, analysis, and often small molecules produced through synthetic chemistry, to the study and manipulation of biological systems.
