RLO: Concentration Gradients
Introduction
A gradient, in general, is the relation between two quantities: higher and lower, lesser and greater, darker and lighter, and so on. Put more formally, it's the change in magnitude of a property, such as height or temperature, from one value to another. The greater the difference between two quantities, and/or the shorter the distance between them, the steeper the gradient. In everyday life, the most familiar type of gradient is that of a hill, but this is only one amongst many types of gradient.
