During the phase and process of the bacterial unknown project, vast amounts of test were performed in order to determine an unknown species of bacteria. Within the many procedures of identifying the unknown bacteria, I was first given a tube with the unknown bacteria, from which later on I started subcultures by streaking bacteria from the original tube onto a tryptic soy agar (TSA) slant. Throughout the process of identifying the unknown, new subcultures were produced in order to use the newest…

This report will compare the water quality of Freshwater Creek over the last three years using chemistry to show how the three chosen parameters are all linked and affect the overall quality of the water. Water is combination of two atoms, oxygen and hydrogen. When two hydrogen’s bond with one oxygen it makes a covalent bond. A covalent bond relates to the outer shell of electrons (valence shell) being shared with the neighbouring molecule for them to bond. A covalent bond only occurs between…

The broad similarity between two articles Ehlers, Worm & Reusch (2008) and Campanella et al. (2013) is that both papers emphasized the importance of the genetic diversity of Zostera marina, an ecologically important plant for coastal ecosystem to survive adverse environmental conditions arising from climate change, catastrophic events (storm, heat waves) and anthropogenic activities (pollution, eutrophication, habitat destruction etc). Ehlers et al. (2008) talked about the effects of temperature…

1. Effect of obstructing hydraulic structures on the fish fauna: Dams, barrages, weirs or navigation locks built on a river for various purposes act as obstruction to the migration of the fishes. Various effects of such hydraulic structures are as follows: a) Barrier to the movement of fish to their spawning grounds. Several fish species require special regions to spawn. These hydraulic structures obstruct the movement of such species to their upstream spawning grounds where they reproduce. As…

Introduction Phytoplankton require nutrients and light to survive. Certain nutrients are a limiting factor in phytoplankton competition and composition. Some phytoplankton are limited by nitrogen while others may be limited by phosphorus (Quigg, 2016). The experiment in this paper will determine if a body of water is limited by nitrogen or phosphorus by running a resource limitation assay. Nutrient levels in bodies of water may change seasonally in a natural way (Vanni and Temte, 1990).…

Front Page: The Rocky Mountain National park in is Colorado. The elevation differences are vast and vary between 8,000 to 14,259 feet. The park is open year round. One of the most popular activities in the park is to observe the vast number of species. The park was created in 1915 and its area is 415 square miles. Carbon Cycle: The carbon cycle is the processes by which carbon is transferred throughout an ecosystem. In a typical carbon cycle, carbon is released in the form of carbon dioxide…

 Hrudey, S. Hrudey, E. and Pollard, S., (2006), “Risk Management for Assuring Safe Drinking Water”, explained the concept that no water can ever maintain the absolute ideal standards thus no water can ever be called safe. Though the population usually wants 100% safe water the percentage of consumer who are ready to accept the flaws is not yet known what is also not clear also is what level of risk is acceptable to the consumers.  Troy W. Hartley, (2006) , “Public Perception and Participation…

Fish have a unique position with respect to their taxonomic and phylogenic status among vertebrates and occupy an important place in vertebrate’s genealogy. Most fish are ectothermic ("cold-blooded"), allowing their body temperatures to vary (1 – 2 ºC) as ambient temperatures change. Majority of siluroid fish are economically important for human consumption. Protein and vitamins content in fish flesh varies from high to moderate and make it as rich source of protein diet. Fishes of siluroid…

Earth and Environmental Science Environmental Impact Statement By Byron Smith Actual Development “Hume Coal Mine “ In the Berrima area located in the NSW southern highlands there has been a proposed coal mine. This coal mine will consist of large stockpile near Berrima (town centre), train loading facilities, a train line and an underground mine. The Hume coal mine is too “extract 3.5 million tonnes of coal… in the next 19 years”. The public have protested about this proposed mine as…

Water is a colorless, transparent and odorless liquid that exists in all three states of matter. It plays three major roles as the: a) universal solvent, b) reactant molecule, and d) temperature stabilizer. Water is created when Hydrogen and Oxygen undergoes synthesis reaction as 2H2 + O2  2H¬2¬O. In the process, an oxygen atom is covalently bonded to the two hydrogen atoms forming a non-linear molecular shape of water. According to the Valence shell electron pair repulsion (VSEPR) theory, the…
