BiochemistryStudy of chemical processes of living organismsBiochemistry, or biological chemistry (distinct from chemical biology), is the study of chemical processes within and relating to living organisms. A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology, and metabolism. Over the last decades of the 20th century, biochemistry has become successful at explaining living processes through these three disciplines.
Atmospheric pressureAtmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101.325 kPa (1,013.25 hPa), which is equivalent to 1,013.25 millibars, 760torr (or about 760mmHg), about 29.9212inHg, or about 14.696psi.
BiologyBiology is the scientific study of life and living organisms. It is a broad natural science that encompasses a wide range of fields and unifying principles that explain the structure, function, growth, origin, evolution, and distribution of life.
MedicineDiagnosis, treatment, and prevention of illnessThe Doctor by Sir Luke Fildes (1891)Medicine is the science and practice of caring for patients, managing the diagnosis, prognosis, prevention, treatment and palliation of their injury or disease, while promoting their health. Medicine encompasses a variety of health care practices which evolved to maintain and restore health through the prevention and treatment of illness and infection.
PHIn chemistry, pH ( or ; ) is a logarithmic scale used to specify the acidity or basicity of aqueous solutions. Acidic solutions (solutions with higher concentrations of hydrogen (H) cations) are measured to have lower pH values than basic or alkaline solutions.
LaboratoryA laboratory (UK: ; US: ; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed.
ElectromagnetismIn physics, electromagnetism is an interaction that occurs between particles with electric charge via electromagnetic fields. The electromagnetic force is one of the four fundamental forces of nature. It is the dominant force in the interactions of atoms and molecules. Electromagnetism describes and relates the three distinct but closely intertwined phenomena of electricity, magnetism, and optics.
Atmospheric chemistryAtmospheric chemistry is a branch of atmospheric science that studies the chemistry of the Earth's atmosphere and that of other planets. This multidisciplinary approach of research draws on environmental chemistry, physics, meteorology, computer modeling, oceanography, geology and volcanology, climatology and other disciplines to understand both natural and human-induced changes in atmospheric composition.
Internal environmentThe internal environment (or milieu intérieur in French; French pronunciation:) was a concept developed by Claude Bernard, a French physiologist in the 19th century, to describe the interstitial fluid and its physiological capacity to ensure protective stability for the tissues and organs of multicellular organisms. EtymologyClaude Bernard used the French phrase milieu intérieur (internal environment in English) in several works from 1854 until his death in 1878.
CelsiusThe degree Celsius is the unit of temperature on the Celsius temperature scale (originally known as the centigrade scale in English), one of two temperature scales used in the International System of Units (SI), the other being the closely related Kelvin scale. The degree Celsius (symbol: °C) can refer to a specific point on the Celsius temperature scale or to a difference or range between two temperatures.*As an Amazon Associate I earn from qualifying purchases.
