- Absorption. Definition. noun. (general) The act or process of absorbing or assimilating. (biology) The process of absorbing or assimilating substances into cells or across the tissues and organs through diffusion or osmosis, as in absorption of nutrients by the digestive system, or absorption of drugs into the bloodstream.elated terms: absorption band, absorption cell, atomic absorption spectrophotometry, cutaneous absorption, external absorption, linear absorption coefficient, specific absorption coefficient. Compare: adsorption.

Assimilation 474 pages on this wiki. Assimilation is where an organism uses molecules which have been absorbed from external substances (e.g. food) and makes them part of the organism.xamples of assimilation include the absorption of nutrients into the body after digestion in the intestine, and their transformation into other molecules; and photosynethesis. This article is a stub, and is very fishy. You can help GCSE Wiki by expanding it, removing the non-GCSE content or improving it.

Biological Attack Fact Sheet: Human Pathogens, Biotoxins, and Agricultural Threats You are here. Biological Attack Fact Sheet: Human Pathogens, Biotoxins, and Agricultural Threats. A biological attack is the intentional release of a pathogen (disease causing agent) or biotoxin (poisonous substance produced by a living organism) against humans, plants, or animals. An attack against people could be used to cause illness, death, fear, societal disruption, and economic damage.

Biological Engineer: Career Information Career Definition. The job responsibilities of a biological engineer are diverse. A biological engineer may study the environment to improve the ways we conserve soil, water and other natural resources. He or she may design new equipment or methods used in medicine or agriculture, or specialize in power systems.ducation Required. A bachelor's degree in biological engineering or a related field is necessary for nearly all entry-level positions. Biological engineer students might choose from four areas of specialization, including environmental, biomedical, bioprocess and agricultural.

Biofilter Biofiltration is a pollution control technique using living material to capture and biologically degrade pollutants. Common uses include processing waste water, capturing harmful chemicals or silt from surface runoff, and microbiotic oxidation of contaminants in air.iofiltration is thus usually referred to as a fixed–film process. Generally, the biofilm is formed by a community of different microorganisms (bacteria, fungi, yeast, etc.), macro-organisms (protozoa, worms, insect’s larvae, etc.) and extracellular polymeric substances (EPS) (Flemming and Wingender, 2010).

Biological Therapy Biological therapy is a form of treatment that uses portions of the body's natural immune system to treat a disease. Biological therapy is also used to protect the body from some of the side effects of certain treatments.Biological therapy often involves the use of substances called biological response modifiers (BRMs).odes of biologic therapy that involve blocking the action of specific proteins of inflammation, called tumor necrosis factor (TNF), are being used for the treatment of a number of diseases, including rheumatoid arthritis and Crohn's disease.

- Bioassay (commonly used shorthand for biological assay or assessment), or biological standardization is a type of scientific experiment.A bioassay involves the use of live animal or plant (in vivo) or tissue or cell (in vitro) to determine the biological activity of a substance, such as a hormone or drug.ioassays are typically conducted to measure the effects of a substance on a living organism and are essential in the development of new drugs and in monitoring environmental pollutants. Both are procedures by which the potency or the nature of a substance is estimated by studying its effects on living matter.

- Because bioaccumulation is the net result of the interaction of uptake, storage and elimination of a chemical, these parts of the process will be examined further. UPTAKE . Bioaccumulation begins when a chemical passes from the environment into an organism's cells. Uptake is a complex process which is still not fully understood.

Biological Attack Fact Sheet: Human Pathogens, Biotoxins, and Agricultural Threats A biological attack is the intentional release of a pathogen (disease causing agent) or biotoxin (poisonous substance produced by a living organism) against humans, plants, or animals. An attack against people could be used to cause illness, death, fear, societal disruption, and economic damage. An attack on agricultural plants and animals would primarily cause economic damage, loss of confidence in the food supply, and possible loss of life.

The Absorption of Food by the Human Body The Absorption of Food by the Human Body. Some nutrients begin breaking down in your mouth. Digestion and absorption begins in your mouth and ends when waste exits your colon. Food is fuel for your body and provides nutrients, which are broken down and absorbed during digestion. Components in foods, including carbohydrates, protein, fat, vitamins and minerals, each have their own function in your system and are metabolized in different ways.

Comments: Absorption vs Adsorption Diffen › Science › Chemistry. Absorption is the process in which a fluid is dissolved by a liquid or a solid (absorbent). Adsorption is the process in which atoms, ions or molecules from a substance (it could be gas, liquid or dissolved solid) adhere to a surface of the adsorbent.Adsorption is a surface-based process where a film of adsorbate is created on the surface while absorption involves the entire volume of the absorbing substance.dsorption is the process in which atoms, ions or molecules from a substance (it could be gas, liquid or dissolved solid) adhere to a surface of the adsorbent.

Biological dispersal Wind dispersal of dandelion seeds. Biological dispersal refers to both the movement of individuals (animals, plants, fungi, bacteria, etc.) from their birth site to their breeding site ('natal dispersal'), as well as the movement from one breeding site to another ('breeding dispersal'). Dispersal is also used to describe the movement of propagules such as seeds and spores.

Biological Hazard Definition - What does Biological Hazard mean? A biological hazard can be described as a threat to human life or health that is posed by a biological substance(s). A biological hazard is caused by biological waste, such as medical waste, micro organisms, viruses, etc. The biological hazards can affect both human and animal life and health in a variety of ways. Some biohazards have the ability to change DNA structures.
