Absorption spectrum

... An absorption spectrum is a diagram depicting the wavelengths of ... can be regarded as the opposite to an emission spectrum , which is a depiction of the specific ... this results in dark absorption lines seen in the spectrum when viewed through a spectroscope . The ...

Optical spectrum

... The optical spectrum ( light or visible spectrum ) is the portion of the electromagnetic spectrum that is visible to the human eye . There ...

Biology

... and individuals come into existence, and the interactions they have with each other and with their environment . Biology encompasses a broad spectrum of academic fields that are often viewed as independent disciplines. Together, they study life over a wide range of scales . Life is studied at ...

Barbiturate

... Barbiturates are drugs that acts as central nervous system (CNS) depressants , and by virtue of this they produce a wide spectrum of effects, from mild sedation to anesthesia . Some also are used as anticonvulsants . Barbiturates are derivatives of barbituric acid. ...

Chlorophyll

... to convert carbon dioxide and water to carbohydrates and oxygen . Chlorophyll absorbs most in the red and blue portions of the electromagnetic spectrum , thus its intense green color. Chemical structure Chlorophyll is a chlorin pigment, which is structurally similar to porphyrin pigments ...

Photosynthesis

... In plants, there are two photosystems involved, which are most active at 700 and 680 nm . However, other wavelengths are also peaks in the action spectrum for photosynthesis. Photosynthesis begins when light ionizes a chlorophyll molecule, releasing two electrons , which are transferred along an ...

Immune system

... innate immune system. Innate immunity fights pathogens using defenses that are quickly mobilized and triggered by receptors that recognize a broad spectrum of pathogens. Plants and many lower animals do not possess an adaptive immune system and instead rely on innate immunity. The study of the innate ...

Magnetic resonance imaging

... relative to those of surrounding regions. MR spectroscopy, however, provides a wealth of chemical information about that region, as would an NMR spectrum of that region. Functional MRI Functional MRI (fMRI) measures signal changes in the brain that are due to changing neural activity. The ...

Photon

... be created and destroyed. Photons are commonly associated with visible light , which is actually only a very limited part of the electromagnetic spectrum . Photons have zero invariant mass but a definite finite energy. Because they have energy, the theory of general relativity states that they ...

Photosynthesis

... In plants, there are two photosystems involved, which are most active at 700 and 680 nm . However, other wavelengths are also peaks in the action spectrum for photosynthesis. Photosynthesis begins when light ionizes a chlorophyll molecule, releasing two electrons , which are transferred along an ...

Pigment

... There are both natural and synthetic pigments, both organic and inorganic ones. Pigments work by selectively absorbing some parts of the visible spectrum (see light ) whilst reflecting others. A distinction is usually made between a pigment, which is insoluble, and a dye , which is either a liquid, ...
