the town of Blackpool‚ UK and this was followed on the 27th May 2011 by a second seismic occurrence of measuring 1.5 on Richter scale. These two events occurred close to Preese Hall drilling site‚ where Caudrilla Resources was extracting gas from a shale deposit using a new method called Hydraulic Fracturing‚ often referred to as Fracking. Immediately after the seismic events attention was focused on Caudrilla Resources and this new unconventional process that extracts natural gas by fracturing the

MULTICELLULAR ORGANISMS The complex multicellular animals and plants perform many different activities in order to exist. More energy is invested in all organisms for their accumulation and distribution of food‚ release of waste matters‚ movement‚ reproduction‚ and coordination of these activities. The different organisms have specialized tissues‚ organs and organ systems that work together for the good of the organisms. Thus the well-being of the whole organism depends on the integration

specific tool known as a Perforation Gun is deployed down the hole vertically and horizontally. When this gun is set off‚ it creates fractures in the Marcellus Shale‚ which is located along Pennsylvania‚ New York‚ and West Virginia. these fractures in the shale then begin to release methane gases. This is a problem because Marcellus Shale has enough natural gases to supply all USA gas needs for 14 years. They then pull out the perforation gun and enter another type of pipe. This pipe is unique because

Hydraulic fracturing is a water-intensive industrial process that drillers use to collect the natural gas held in shale formations. Shale gas has become an increasingly important energy resource in the U.S. Fracking fluid contains water‚ salt‚ sand‚ and hazardous industrial chemicals. This fluid is injected at high pressure underground into geologic formations. The salty water‚ sand‚ and chemical mixture forces natural gas up through the well bore to the surface for collection through pipelines.

The term microorganisms consist of bacteria‚ archaea‚ fungi‚ and protest‚ which can either be unicellular or multicellular. They first have been studied by Anton van Leeuwenhoek by the use of his own design microscope‚ in 1675. However‚ they have been an attractive source of study for many scientists‚ since they live in all parts of biosphere and are critical to nutrient
