areas smell or taste like a chemical gas? The most likely reason for both of these effects is fracking. Hydraulic fracturing‚ as known as fracking‚ is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks to release natural gas inside (Dong). According to many recent research studies fracking is very harmful to the environment and shouldn’t be done here in Coppell‚ but how so? You need to understand the fracturing fluid that is used

the extreme temperatures. Schist is a medium grained rock that is formed from shale which is a sedimentary rock or mud but at a higher temperature than slate. Schist can form in several different ways. One of the most common ways that is formed is when shale is transformed into slate‚ then phyllite and then schist. After this transformation schist is changed into gneiss. During this process the clay particles in the shale into micas and increases their size. The micas will finally begin to recrystallize

known as the Marcellus shale line‚ and it is in four different regions in the U.S. spread over thirty states. Historically gas companies would drill for their gas‚ but in recent history have developed a process of Hydraulic Fracturing which at one job can use one million gallons of fresh water‚ and over nine hundred chemicals‚ to include Benzene and various heavy metals (Gasland). Once this mixture is forced eight thousand feet into the earth’s crust it destroys the shale and releases the natural

of Fracking Introduction Fracking‚ or hydraulic fracturing‚ is the process of extracting natural gas from shale rock. Fracking allows the world to retain natural gas from depths that were deemed unreachable by conventional technology. Recent advancements in Fracking technology have propelled America to the forefront of natural gas extraction. By this method‚ the shale rock is punctured with a high pressure fluid‚ causing it to rupture and allow the movement of petroleum and brine. After

(not transcribed) • Tandem- side by side • Short tandem repeats- can be repeated up to 100 times at a particular chromosomal location. The copy number of an STR at a particular location varies between individuals and is inherited. • Moderately repetitive sequences- repeated 10-1000 times in eukaryotic

Phylogenetic estimates constructed with bacteria‚ plastids‚ and eukaryotic genomes also suggest that plastids are most closely related to cyanobacteria. * Mitochondria have several enzymes and transport systems similar to those of bacteria. * Some proteins encoded in the nucleus are transported to the organelle
