Absorption Spectra
An absorption spectrum is a spectrum of radiant energy whose intensity at each wavelength is a measure of the amount of energy at that wavelength that has passed through a selectively absorbing substance.
absorption -- The taking in of water and dissolved minerals and nutrients across cell membranes. Contrast with ingestion.
aerobic -- Pertaining to the presence of free oxygen. Aerobic organisms require oxygen for their life processes.

absorption The process by which the products of digestion are transferred into the body's internal environment, enabling them to reach the cells.
absorptive feeders Animals such as tapeworms that ingest food through the body wall.

The absorption of the cerebrospinal fluid is a dual process, being chiefly a rapid drainage through the arachnoid villi into the great dural sinuses, and, in small part, a slow escape into the true lymphatic vessels, ...
The absorption of a fluorophore depends on the polarization angle of the excitation light, and fluorescence emission is also polarized. Fluorescence polarization is used to detect the direction and rotation of molecule movement.

The main function of the opsin is to change shape after light absorption triggers the isomerization of the chromophore: the opsin is an enzyme that is activated by the chromophore's isomerization.
Cells that are specialized for absorption (ex: intestinal cells) have folds in the plasma membrane called microvilli that increase the surface area.
This can arise when the absorption, distribution and utilization of iron is affected. Alternatively, chelating agents can induce toxicity by directly interfering with iron dependent metalloenzymes located within the body.

collecting tubules
That part of the renal tubule in a kidney in which water absorption takes place under the control of ADH, producing urine of variable concentration depending on overall water levels in the body.
feeder roots. The youngest roots with root hairs, important in absorption of water and minerals.
field capacity. The moisture level in soil after saturation and runoff.

[Gr. osteon - bone; Gr. klastos - broken in pieces]. A multinucleated cell that breaks down bone through reabsorption.
Photoinduced charge separation The excitation of an electron from its ground state to a higher energy level by light absorption and the subsequent movement of the excited electron from the initial molecule to an acceptor, ...

Some fish (lungfish) can survive out of the water for a while, but amphibians were designed for it. One hitch: they need the water when they are kids. Amphibians also use their skin to absorb oxygen from the air. The absorption process is more ...
