Innovation‚ diffusion‚ and acculturation are the processes of how culture is changing. Innovation is taking existing technology and resources and creating something new to meet a need. For example‚ to solve the need for storage goods‚ some societies invented baskets woven from reeds because reeds were abundant. Diffusion is the spread of ideas‚ inventions

experiment on the effect of surface area to volume ratio on the rate of osmosis of Solanum tuberosum L._ BACKGROUND A cell needs to perform diffusion in order to survive. Substances‚ including water‚ ions‚ and molecules that are required for cellular activities‚ can enter and leave cells by a passive process such as diffusion. Diffusion is random movement of molecules in a net direction from a region of higher concentration to a region of lower concentration order to reach equilibrium. Diffusion does not
