Denitrification

found in organic matter goes from ammonia (NH3-) to ammonium salts (NH4+). * The process of nitrification converts ammonia (NH3) to nitrogen dioxide (NO2). The chemical formula is NH3 + 1.5 O2 --> NO2- + H+ + H20. Nitrogen Cycle Steps (part 2) * Denitrification is the process where nitrate leaks to the ocean or the soil and is then returned to the atmosphere. * Plants can absorb nitrates (NO3-) as well, which is turned back into the cycle when these plants are consumed by animals. Nitrogen…

The illustration above is a good summary for the people who have knowledge about Chemistry, Biology, and Geology. However, it is challenging to understand for people who do not have knowledge in the fields mentioned above. It is so important to give an interpretation so that those people can understand this report. Photosynthesis: This is the process by which plants create their own nutrient by using sunlight. Sunlight acts as the convertor to transform carbon dioxide (CO2) into organic…

Kumale Fufa Ramisha Islam 18 November 2014 Period 1, Period 2 The Effect of Different Levels of Nitrate and Phosphate in Fertilizer Runoff Before and After Rain Water is a major resource and is essential for life. It is naturally recycled through a process called hydrological cycle. The demand of water over the world has been increasing as population and industrialization does, while available drinking water has been deteriorating due to pollution.Fertilizer runoff is a serious…

By collaborating our work from various resources, we established that antibiotics have harmful side effects on the environment. When animals are administered antibiotics, it kills off other bacteria and allows antibiotic resistant bacteria to survive and multiply. This causes contamination of animal waste, which then comes into contact with water, soil, or air (Food, Farm, Animals, and Drugs 2014). Horizontal gene transfer is also a big concern for the environment. In recent years, there has…

Ammonia is a compound composed of nitrogen and hydrogen, having the formula NH3. The ammonia molecule is formed by sp3 orbitals as it has a tetrahedral geometry and a trigonal pyramidal shape. Ammonia has an experimentally determined bond angle of 106.7°, and an a bond length of 101.7 pm. The nitrogen atom in the molecule has a lone electron pair, which gives the molecule a dipole moment and polarity. Ammonia’s lone electron pair makes NH3 a base, a proton acceptor, and gives it the ability to…

Concentrated Animal Feedlot Operations and Their Risks Following Michael Pollan’s view in his book, The Omnivore’s Dilemma, he covers the realm of concentrated animal feedlot operations (COFAs) in his extensive spiel about the overarching concept of corn in our society. He discusses his purchased steer, number 534, as he accompanies its journey through the system. In the beginning 534 enjoyed his life on a green pasture with his mother for six months, until he became strong and bulky enough to…

Energy Flow and Nutrient Cycling in the Epipelagic Zone of the Ocean Introduction: “Energy Flow’’ is an environmental process that describes the flow of energy through a food chain and attempts to ascertain the relative importance of various individual component species and feeding relationships within a particular ecosystem. “Energy” itself is defined as the ability to do work: All living plants and animals expend energy in their environment. All three laws of thermodynamics apply,…

A. 1. This week’s session on sustainability hit very close to home with me. My adult children have been altering their consumption habits by buying organic, antibiotic free, and non-gmo products over the last few months. They have also been purchasing either free range or locally grown meats, local meat markets. After reading “A Meat Eater’s Guide to Climate Change”, I also altered my buying habits for the week. I knew, from my daughters, that there were health benefits to eating organic…

Following Gram staining and microscopic examination, Unknown 15 was identified to be a Gram positive coccoid. Based on these results, all of the Gram negative genera were eliminated including: Enterobacter, Citrobacter, Klebsiella, Escherichia, Pseudomonas, Serratia, Alcaligenes, Neisseria, Proteus, Salmonella, Shigella, Erwinia, Veillonella, and Flavobacterium (5). Bacillus, Lactobacillus, Listeria, Kurthia, and Arthrobacter were eliminated because they did not match the coccoid shape of…

Introduction This practical consisted of using a microscope on two different types of samples, human hair and Lily pollen to acquire the basics of using a microscope. Three different types of objective lenses were used (4x, 10X and 40X). Furthermore it gave an insight to particulate matter in the air. Q1. Table 1 below shows the diameter of a human hair under previous stated objective lenses Standard deviation is used in this case to quantify the amount dispersal or variation in the results.…
