pressure to the surrounding area until it cracks. The target area for oil and gas drilling companies is in the shale‚ a soft layer of sedimentary rock broken apart by using a mixture of 98% water and 2% chemicals. These chemicals range from household cleansers to toxic chemicals‚ and is added to nearly 4 million gallons of water per drilling well. By using this mixture and pressure the shale is cracked releasing gas and oil reserves trapped inside. Fracking has been proven to cause earthquakes‚ producing

the hydrogen electrons and the energy is used to make ATP. The H’s are ultimately accepted by O2 to make H2O as an endproduct. Respiration occurs in three major stages: 1) Glycolysis – occurs in the cytoplasm for both prokaryotic and eukaryotic cells • One glucose (6C) is broken into two 3C molecules – 2 pyruvic acids (pyruvate) • One oxidation step produces two molecules of reduced coenzyme – 2NADH • One step produces energy in the form of ATP – 2ATP

The Evolution of Life This section provides information about the evolution of life on Earth. For reasons of simplicity some important events and life forms were selected for each geological time span. However this should not give the impression that the evolution of life on Earth is or was a sequential event. Many life forms that were not mentioned in this text were very successful and have evolved or in some cases maintained a very successful life strategy. Prokaryotes‚ for example are the most

Discussion on the Ethical Implications of Hydraulic Fracturing by: Sebastian Potes 7/16/13 ! Abstract As concern grows over the environmental impact of hydraulic fracturing‚ implementing policy that protects people and their environment from these potential dangers becomes an essential piece of the renewable energy picture. Hydraulic fracturing‚ or fracking‚ is the technique of extracting oil and natural gas trapped under ground by injecting a mixture of water‚ sand‚ and chemicals into the

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane. The cell is the very smallest unit of living matter. All living things including plants and animals are made up of cells. Cells are made of atoms‚ which are the smallest units of matter. There are many different kinds of cells. The two kinds you are most likely to be familiar with are animal and plant
