Gradient definition in biology
WebIn biology, a cline (from the Greek κλίνειν klinein, meaning "to lean") is a measurable gradient in a single characteristic (or biological trait) of a species across its geographical range. First coined by Julian Huxley in 1938, the "character" of the cline referred to is usually genetic (e.g. allele frequency, blood type), or phenotypic (e.g. body size, skin pigmentation). WebWord & Picture Definition Protein pump Found in the cell membrane and is responsible for pushing molecules up their concentration gradient into or out of a cell. This requires ATP and is commonly used to move protons, sodium and potassium. This describes the cell membranes ability to let some items pass directly though while preventing others. Small, …
