and Diffusion Lab Report Background Information: Diffusion involves the movement of solute particles across a selectively permeable membrane from higher to lower concentrations. A selectively permeable membrane allows only some thing to go through. Water and oxygen are examples of molecules that are able to go through the membrane by diffusion. The

Applying Diffusion of Innovations Theory November 14‚ 2010 COM 126 K. Vook Once innovation occurs‚ innovations may be spread from the innovator to other individuals and groups. In 1962‚ Everett Rogers proposed that the life cycle of innovations can be described using the “s-curve” or diffusion curve. The s-curve maps growth of revenue or productivity against time. In the early stage of a particular innovation‚ growth is relatively slow as the new product establishes itself. At some point

Michelle Yeung Bio 101 Cyrus MacFoy June 16‚2015 Diffusion and Osmosis Exercise I. Molecules are always in constant movement. Molecular motion is a form of energy‚ the kinetic energy of molecules. The Brownian movement is the movement of small particles caused by the bombardment of the particles by millions of water molecule. This movement will continue indefinitely as long as there is water. My prediction for this lab is the solution of the water is hypertonic meaning there is a higher concentration
