in the artificial cells to the diffusion rate using the phenolphthalein-NaOH agar and the HCl solution. Lab #2 was a model of diffusion and osmosis‚ in which we filled the model cells with different solutions and determined the rate of diffusion. In lab #3‚ the results demonstrated the interactions between selectively permeable membranes‚ water‚ and solutes and how they are important in cellular and organismal functions. In lab #1‚ the results showed the diffusion rate between the certain time period

Examining Diffusion and Osmosis Introduction: Purpose: 1. To simulate and observe the diffusion of solutes and the osmosis of water through a semipermeable membrane through color change and sugar tests. 2. To speculate osmosis occurring in dialysis bags and potato cores by comparing percentage change in masses. Background information: Molecules are always in random‚ constant movement due to their kinetic energy. This causes the molecules of a cell to move around and bump into each other

LabMr.P/Pd. 63/17/14 Osmosis and Diffusion Lab Osmosis is a process where molecules pass through a semi permeable membrane from a less concentrated solution into a more concentrated one‚ equalizing the concentrations on each side of the membrane. Diffusion is the spreading of something more widely.During the osmosis and diffusion lab I tested what happens to a fresh egg when osmosis and diffusion across membranes. The eggs were placed in vinegar‚ distilled water‚ and then lastly syrup. The

Innovation‚ Entrepreneurship & CSR Summary Chapter 1: The Innovation Imperative Innovation matters – the logic is simple‚ if we don’t change what we offer the world and how we create and deliver them‚ we risk being overtaken by others who do. At the limit it is about survival – and history is very clear on this point; survival is not compulsory. Innovation is strongly associated with growth. New business is created by new ideas‚ by the process of creating competitive advantage in what a
