61Symporter — How it works A symporter is an integral membrane protein that is involved in movement of two or more different molecules or ions across a phospholipid membrane such as the plasma membrane in the same direction, and is therefore a type of… …
62ATP synthase — Molecular model of ATP synthase by X ray diffraction method ATP synthase (EC 3.6.3.14) is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP). ATP is the most commonly used energy… …
63Debye sheath — The Debye sheath (also electrostatic sheath) is a layer in a plasma which has a greater density of positive ions, and hence an overall excess positive charge, that balances an opposite negative charge on the surface of a material with which it is …
64human cardiovascular system — ▪ anatomy Introduction organ system that conveys blood through vessels to and from all parts of the body, carrying nutrients and oxygen to tissues and removing carbon dioxide and other wastes. It is a closed tubular system in which the… …
65Self-creation cosmology — (SCC) theories are gravitational theories in which the mass of the universe is created out of its self contained gravitational and scalar fields, as opposed to the theory of continuous creation cosmology or the steady state theory which depend on …
66Peek's law — In physics, Peek s law is a description of the conditions necessary for corona discharge between two wires::e v = m v g v delta r ln left ({S over r} ight ) e v is the visual critical corona voltage or corona inception voltage (CIV), the voltage… …
67Electrofishing — before they are caught. Electrofishing is a common scientific survey method used to sample fish populations to determine abundance, density, and species composition. When performed correctly, electrofishing results in no permanent harm to fish,… …
68Xerophyte — The Joshua tree is an example of a xerophyte. A xerophyte or xerophytic organism (from Greek xero dry, phuton plant) is a plant which has adapted to survive in an environment that lacks water, such as a desert. Xerophytic plants may have adapted… …
69Membrane technology — The membrane technology covers all process engineering measures for the transport of substances between two fractions with the help of permeable membranes. That means in general mechanical separation process for separation of gaseous or liquid… …
