and is focused on determining the stress that various alcohols have on biological membranes. Using five solutions of differing alcohol concentration for each of the three alcohols; methanol‚ ethanol‚ and 1-propanol and a small slice of beet‚ the stirred solution was placed into a plastic cuvette and then into a spectrophotometer and the absorbance of alcohol solutions were determined in order to conclude which alcohol and concentration of alcohol had the greatest effect on biological membranes. The

Energy conservation helps ensure available resources for future generations and also helps prevent pollution. Most of our current energy sources today are not renewable‚ which means that they will eventually deplete. As a member of the Home Owner’s Association I believe that it is extremely important for us to educate our community about the importance of energy conservation. Teaching the community that energy is not a right but a privilege will educate‚ empower‚ and make us aware of the importance

Energy conservation refers to reducing energy through using less of an energy service. Energy conservation differs from efficient energy use‚ which refers to using less energy for a constant service. For example‚ driving less is an example of energy conservation. Driving the same amount with a higher mileage vehicle is an example of energy efficiency. Energy conservation and efficiency are both energy reduction techniques. Even though energy conservation reduces energy services‚ it can result in
