Diffusion and osmosis are important because they provide . evidence. for the existence and movement of particles, that is, they provide . evidence. osmosis . active transport. in . cells . Movement of molecules into and out of cells. T. ransport can be passive or active.. P. assive requires no energy and moves down a concentration gradient from high to low concentration. and Osmosis. Diffusion . is the movement of particles from an area of high concentration to an area of low concentration. When a particle moves from an area of high concentration to an area of low concentration, it is said that it is moving down its . WHAT IS CULTURE??. 2. 3. Culture. All-encompassing term that identifies not only the whole tangible lifestyle of peoples, but also their prevailing values and beliefs. Cultural trait. – a defining characteristic that is shared by most, . Molecules are always moving. Molecules move randomly and bump into each other and other barriers. Concentration gradient.
