Abstract The cytoplasm and extracellular environment of the cell are aqueous solutions. They are primarily composed of water (the solvent)‚ and a variety of dissolved solutes‚ such as sugars‚ amino acids‚ and ions. The plasma membrane of the cell is selectively permeable‚ allowing water to freely pass through‚ but regulating the movement of solutes. Water and some dissolved solutes move via passive diffusion through the plasma membrane. Diffusion is a process where molecules move from an area of

Case study: 1. With regard to the normal ageing process. Discuss expected changes that may occur. A. The Musculo-skeletal system? Aging changes in the musculoskeletal system can lead to decreased mobility‚ increase in pain‚ lower activity‚ the ability to maintain strength and co-ordination. Regular exercise can maintain strength and function and help reduce risk of falls‚ reduce pain and help the older person in maintaining levels of independence. The Musculo-skeletal is made up of
