Detailed explanation-1: -“Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.”
Detailed explanation-2: -In physics and chemistry, diffusion is basically defined as the “spreading out” of the objects from the initial area of higher concentration. Diffusion in biology applies the same principle but the process involves a biological system, such as a semipermeable membrane.
Detailed explanation-3: -Diffusion: the spread of ideas, languages and technologies from one area to another. Trade and human migration often lead to diffusion. The spread of Islam to South Asia or Buddhism to East Asia are examples of diffusion.
Detailed explanation-4: -Diffusion is the movement of a substance from an area of high concentration to an area of lower concentration . Diffusion occurs in liquids and gases when their particles collide randomly and spread out. Diffusion is an important process for living things-it is how substances move in and out of cells.
Detailed explanation-5: -Contagious diffusion: rapid widespread diffusion of a characteristic throughout the population.
