Released Into The Atmosphere Sulfur Dioxide
1,318 wordsEvery thing present in this universe is a part of environment including ourselves. Whether they are animals, living thing, or nonliving things. All of the external factors affecting an organism. These factors may be other living organisms (biotic factors) or nonliving variables (abiotic factors), such as water, soil, climate, light, and oxygen. All interacting biotic and abiotic factors together make up an ecosystem. Organisms and their environment constantly interact, and both are changed by th...

Effects Of Acid Acid Deposition
770 wordsAcid Rain is a type of air pollution, formed when oxides of sulfur and nitrogen combine with atmosphere moisture to yield sulfuric and nitric acids, which may then be carried long distances from a source before they are deposited by rain. This pollution may also be snow, fog, or a dry form of precipitation. Acid rain is currently a subject of great controversy because of widespread environmental damage for which it has been blamed, including eroding structures, injuring crops and forests, and th...

Copper In Nitric Acid
554 words3 Cu + 8 HNO 3 -- 3 Cu (NO 3) 2 + 2 NO + 4 H 2 O The balanced equation seen on the top is what you attain when you place copper metal in concentrated nitric acid. In this process the identifiable characteristics of the metal will be completely changed and a new substance, cupric nitrate, will be formed. Copper forms two series of chemical compounds: cuprous, and cupric. Cuprous compounds are easily oxidized to cupric, in many cases by simple exposure to air; cupric compounds are stable. When nit...

000 Square Miles Acid Rain
1,060 wordsThe Adirondacks are a group of mountains surrounded by many lakes and rivers, that cover over 5, 000 square miles in the northeastern part of New York. There are a lot of large tourist villages on every lake. Motor boating and other water activities take place on almost every lake in the area. It is a vacation paradise for thousands. But, industrial emissions from Canada and the Ohio river valley always drift to this area and cause acid rain. This silent killer is destroying these beautiful lake...

Hip Hop Gang Violence
1,734 wordsol> In searching for a properly post-modern style of music, it may be better to look at the electronic music scene, which began with house music in the early to middle 80 s, rather than at hip-hop. It is true that the hip-hop artist generally disappears into the narrative of the music to the extent that many of their lives are a direct reflection of what they sing about: gang violence, drugs, racism, alienation in the US, etc. but here already we encounter two problems. One is the existential ch...

2 H 2 O Creatine Phosphate
1,714 wordsWith the aid of diagrams provide a summary of how the following energy systems work. Energy systems; introduction Energy systems are cellular levels processes used to produce Adenosine Triphosphate (ATP) figure 1. This is an adenosine molecule linked to three high-energy phosphates that acts as an energy store for the cell. The energy is released when ATPase, an enzyme, reacts with ATP to produce ADP and Pi, e. g. ATP ADP + Pi There are three energy systems that do this; The Creatine Phosphate S...

The bleeding is a result of an ulcer eroding into a blood vessel of the stomach or small intestine. The signs of bleeding are vomiting bright red blood, or a bowel movement consisting of bloody, or tarry, black stool. If the hemorrhage is very severe, weakness, shock, and loss of consciousness may occur. Obstruction of the digestive tract is another emergency complication of pep...

Western United States Effects Of Acid Rain
399 wordsEffects of Acid Rain on Water The effects of acid rain are most clearly seen in the aquatic, or water, environments, such as streams, lakes, and marshes. Acid rain flows to streams, lakes, and marshes after falling on forests, fields, buildings, and roads. Acid rain also falls directly on aquatic habitats. Most lakes and streams have a pH between 6 and 8. However, some lakes are naturally acidic even without the effects of acid rain. Lakes and streams become acidic (pH value goes down) when the ...

Lactic Acid Unicellular Organisms
244 wordsFermentation is the breakdown of pyrrhic acid without the use of oxygen. Some scientists refer to the combined processes of glycolysis and fermentation as anaerobic respiration. The metabolism of pyruvicacid during fermentation does not produce any ATP. The function of fermentation is to break down pyrrhic acid and regenerate NAD forrest in glycols, where ATP is formed. Fermentation occurs in the forms of lactic acid fermentation and alcoholic fermentation. Lactic acid fermentation occurs in ani...
