Fuel From Plastic Waste Introduction: Household items made of various kinds of plastic. Plastic is the general common term for a wide range of synthetic or semisynthetic organic amorphous solid materials used in the manufacture of industrial products. Plastics are typically polymers of high molecular mass‚ and may contain other substances to improve performance and/or reduce costs. Monomers of Plastic are either natural or synthetic organic compounds. The word is derived from the Greek

Cell Osmotic Fragility‚ Solute Permeability and Diffusion Potentials of Permeable Membranes Introduction This experiment examines cell membrane permeability‚ osmosis and membrane voltages; all of which are important in understanding how cells are affected by their environment. The movement of water across membranes is important for cell volume and thus the volume of extracellular compartments. The mechanisms for solute transport are essential in maintaining cell functions and homeostasis. Furthermore

Mass production of food and the effect on its consumers and the community. Mass production of food and the effect on its consumers Abstract Where does the food we consume come from? We go to the grocery store and always know that the products we want will be there. Nothing runs out and we can pick up whatever we need. Meat‚ eggs‚ produce and even convenient frozen pre-made meals. But before we pick it up in the grocery store we never see

Greenhouse effects and global warming are an uprising environmental issue. The greenhouse effect is the process by which absorption and emission of infrared radiation by gases are released in the atmosphere. The major greenhouse gases are water vapor (36 -70%)‚ carbon dioxide CO2 (9-26%)‚ methane CH4 (4-9%)‚ and ozone O3 (3-7%). Since the industrial revolution‚ human activity has increased the amount of greenhouse gases‚ leading to increased levels of CO2‚ methane and troposphere ozone. Fossil fuels
