The water quality of the U-High Creek has been tested to be excellent. However, that does not mean that every creek is pure or excellent. Some people, more specifically farmers, use fertilizers made from Nitrogen and Phosphorus to kill pests or bugs. Little do they know, the pesticide or fertilizers get into streams and creeks and contaminate it leaving algae growing more rapidly or consistently. Consequently, if the algae overfills the creek, organisms will then die out from oxygen shortage…

Phosphorus Reduction: The New Pig in Town The 21st century is one abloom with scientific and technological advancement. From the sequencing of the human genome to the development of touchscreen phones, this century, albeit just beginning, has already surmounted the expectations of what people ever imagined possible. Advances in genetics have become especially important to swine production and, consequently, to the environment as well. Excess phosphorus in manure has the potential to runoff into…

what is essentially the mixture of the firework together in a paste like mixture. 2. What are the most abundant elements found in the human body? Almost 99% of the mass of the human body is made up of six elements called oxygen, carbon,hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is made up of another five elements called potassium, sulfur,sodium, chlorine, and magnesium. These elements are necessary to life. 3. Which element has the lowest melting point? The chemical element…

Christian Friedrich Schonbein One of the more obscure scientists, Christian Friedrich Schonbein was well known for his discovery of ozone as well as work on fuel cells. He along with Friedrich Goppelsroeder discovered and coined capillary analysis, and later on, paper chromatography. My project centers on ink chromatography and capillary action, both of which were discovered by Friedrich Goppelsroeder and Christian Friedrich Schonbein. Of the two men, Christian Friedrich Schonbein was a more…

highly enriched by nutrients associated with natural erosion of fertile soils, such as lakes located in areas of rich agricultural soils. The nation’s waterways contain excessive amounts of nitrogen from fertilizer. As a result of all this excessive nitrate, algae and other microorganisms take up the nitrogen, bloom and, after they die, suck the oxygen out of coastal waters. These nitrates and oxygen molecules that plants need to grow eventually find their way into rivers, lakes, and oceans and…

The catechol estrogens can give rise to semiquinones and o-quinones by any oxidizing enzyme or transition metal ions such as Cu2＋ or Fe3 [66, 67, 68]. ROS including superoxide anion radicals and hydroxyl radicals is generated when semiquinones are converted to o-quinones and o quinones are reduced back to catechols and semiquinones. These metal ions and hydroxyl radicals are responsible for oxidative damage to DNA, lipids and proteins [69, 70]. Sulfation of E2 leads to decreased hormonal…

available to medical science since 1935. These treatments are for respiratory diseases like bronchiolitis, chronic obstructive pulmonary disease (COPD), asthma, and croup. Helium replaced the role of nitrogen, which was used in earlier attempts as a carrier gas, because it is less dense than nitrogen and allows easier breathing and the absorption of oxygen into the bloodstream occurs more readily. The use of heliox therapy is also done for conditions that do…

AHCSOL303 Assignment 3- soil amelioration report 1.i have a soil that does not absorb water, and when i water it the water pools on the surface and does not infiltrate. What is wrong with my soil? The soil could either be hydrophobic or heavily compacted. Hydrophobic soil is where the surface tension does not allow for infiltration of water because of a waxy layer, which cause the water to form into little beads and can form a pool on the surface. Heavily compacted soil is soil that has…

While trying to find a life lengthening elixir Chinese alchemists invented the deadliest powder in the world. In the 9th Century Chinese alchemists were trying to find a potion of immortality. However they ended up finding a potion of death unlike anything else. The first ever mixture was 75 percent saltpeter or more commonly known as potassium nitrate, 15 percent sulfur, and 10 percent charcoal. After the invention of gunpowder the Chinese people initially used it for fireworks. It was not…

The earth is reliant on various reproductive biochemical cycles, to maintain balanced and regulated conditions on earth and within the atmosphere (Name, date). These cycles include the carbon, nitrogen and hydrological cycles. These cycles among others, bring with them various geological, chemical, physical and biological processes (name, date). All these cycles are interconnected; matter within them is continually cycled between biotic and abiotic parts of the environment (name, date). Without…
