Title : How to reduce use of Electricity Introduction Electricity is a secondary source of energy. Primary sources of energy are oil‚ coal‚ uranium or the forces of nature. Energy is a source of usable power‚ needed for food production‚ transportation‚ heating‚ cooling‚ and lighting. The largest sources of energy in the world are oil (34%)‚ coal (26.5%)‚ and gas (20.9%)1‚ adding up to over 80% of global energy. These types of fuels are called fossil fuels because they are found in fossil

Diffusion‚ Osmosis and Active Transport Substances will move through the membrane by diffusion. This is the random spreading out of particles until they are even. For example‚ when you put your instant coffee in boiling water‚ the coffee particles spread out and fill the entire mug‚ this is diffusion. A second way that substances can move through the cell membrane is by osmosis. This is a special type of diffusion where water moves from a high to a low concentration through a ’partially permeable

Cell Transport Mechanisms Essay There are two methods of moving molecules across the cell membrane‚ passive transport and active transport. Passive transport doesn’t use energy‚ while active transport does use energy. Passive transport allows molecules to move on their own according to natural laws of physics. The three types of passive transport mechanisms include diffusion‚ osmosis‚ and facilitated diffusion. Diffusion is the movement of materials from an area of most concentrated to

Having just bought a new bicycle for my birthday‚ I spent that afternoon practicing my stunts. I called my neighbour who is also my best friend to accompany me into a multi-storey car park adjacent to my block of flats. The place was deserted and cars seldom entered and left in the afternoon. I and my friend‚ Stamford‚ thought it was safe to try my stunts. Pedalling furiously‚ we zoomed up the slope. When we reached the top‚ I spun around on one wheel and zoomed down again. Stamford did the same

Prisons are already filled beyond maximum capacity‚ and we continue to keep incarcerating more people. What can be done to end the problem of prison overcrowding and maintain the safety of the public? I chose this topic because I wanted to shine a light on what I consider to be an injustice. I believe that the criminal justice system needs a complete overhaul. When I chose this topic‚ I wasn’t fully aware of the mandatory sentencing guidelines or how harsh they were. I always believed that judges
