“How Corn Conquered America” I. The main idea of the “introduction” is: corn is the cornerstone of many American’s diet, managing to become the most widely planted crop in America. One fact or example that supports the main idea is about 40 percent of Mexicans calories come directly from corn, mostly in the form of tortillas. Yet Americans have more corn in their diet diet than Mexicans. Another fact or example that supports the main point is that there are some 45,000 items in the average…

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…

The powder do not affect the chemical structure of the magnesium in the fire extinguishing process. However, a protective coat of magnesium oxide is formed on all the surface of the magnesium as it reacts very fast with air. This layer makes it hard for it continue burning. However, in case water is used when removing the residues even after several days, the fire may reignite. The water will…

We have one planet to live on. Have you ever thought of that? We only have this one giant rock, hurtling through the sky at speeds too fast for us to even comprehend; and we have nowhere else to go. Yet, we still take advantage of our home. We pollute it, mine mountains, clear-cut forests and think nothing of it. In everyday life people normally like to keep their home clean and tidy, they may buy insurance to help them buy a new one if something happens to their old one. Earth is our home, yet…

resulting in ammonia. Nitrification is a process by which ammonia is oxidized to nitrite and then nitrite is oxidized to nitrate. Denitrification is a process by which nitrate is converted into nitrogen gas or nitrous oxide by denitrifiers. Nitrogen fixation is a process by which atmospheric nitrogen is converted into ammonia by symbiotic or non-symbiotic mechanisms. 2. The distinguishing difference between the three types of soil used (cactus soil, peat moss, and all-purpose potting soil)…

The aim of this experiment was to determine the percentage composition of magnesium and oxygen in magnesium oxide and evaluate if the composition varies or remains constant. To test this, magnesium was heated and made to react with the oxygen gas in the atmosphere. This reaction formed the ionic compound, magnesium oxide. The percentage composition was later calculated based on the results of the experiment as shown in the above calculations, Figure 4. These results were compared to the expected…

Why is ammonia important? The primary use of ammonia (NH3) is to provide nitrogen atoms for plants so they are able to make amino acids, proteins, and other biologically important molecules. In order to provide the vast amount of food demanded by a growing industrialised population, more efficient agricultural techniques and larger scale farms must be employed. There exists some naturally occurring nitrogen fixing bacteria that are able to convert atmospheric N2 into the more useful form of NH3…

be produced. The amount needed is more than what can be produced naturally so fertilizers are pumped into the soil to produce enough crops. National Geographic says almost half of the nitrogen found in our bodies’ muscle and organ tissue started out in a fertilizer factory. Also that the effects of too much nitrogen are present all around the world. Some major changes are in China. Dan Charles talked to a long time resident of China who claimed that when he was a boy he could see clearly through…

A 2010 survey of 14 industrialized countries found that skepticism about the danger of global warming was highest in Australia, Norway, New Zeeland and the United States, in that order, correlating with high per capita emission of carbon dioxide(Wikipedia). Furthermore there are so many ways society is damaging the ecosystem, some of these issues are brought upon by nature, but the majority of them are caused by man-made pollutants. One issue that is becoming large scale is global warming.…

possibility is that in monoculture for higher urease activity, N-fertilizer rate was same in monoculture and intercrops, and intercrops utilized soil urea faster than monoculture. Nitrite reductase, protease and nitrogenase play significant roles in nitrogen cycle and higher activities of these enzymes showed that vital microbial community enhanced in intercropping system. The nitrogenase enzyme catalyzes the reduction of atmospheric dinitrogen to ammonia. This process is energy expensive and…
