The Nitrogen Cycle Nitrogen fixation Atmospheric nitrogen must be processed‚ or "fixed" to be used by plants. Some fixation occurs in lightning strikes‚ but most fixation is done by free-living or symbiotic bacteria. These bacteria have an enzyme that combines gaseous nitrogen with hydrogen to produce ammonia‚ which is then further converted by the bacteria to make their own organic compounds. Conversion of N2 The conversion of nitrogen (N2) from the atmosphere into a form readily available

THE CARBON CYCLE According to the United States Environmental Protection Agency (“EPA”)‚ the increase in anthropogenic CO2 emissions has led to the increase in global temperatures in the past century . Because of the preponderance of evidence linking greenhouse gases and climate change‚ governments worldwide are developing policy to reduce CO2 emissions. CO2 can enter the atmosphere by burning fossil fuels‚ in manufacturing processes‚ and other energy-reliant activities. However‚ not all emitted

LIFE CYCLE COSTING Life cycle costing (LCC) is the process of collecting‚ interpreting and analyzing data and using quantitative tools and techniques to predict the future resources that will be required in any life cycle of a system of interest. LCC can also be defined as a technique to establish the total cost of ownership. It is a structured approach addresses all the elements of this cost and can used to produce a spend profile of a product over its life span. The result of LCC usually

Elena Chen CH 221-227 November 3rd‚ 2009 Lab Report #3: Copper Cycle Abstract: The purpose of the experiment is to cycle solid copper through a series of five reactions. At different stages of the cycle‚ copper was present in different forms. First reaction involves reaction between the copper and nitric acid‚ and copper changed from elemental state to an aqueous. The second reaction converted the aqueous Cu2+ into the solid copper (2) hydroxide. In the third reaction Cu(OH)2 decomposed into

Hydrologic Cycle March 3‚ 2013 With every year that passes more and more fossil fuels are being released into the atmosphere. Over the past decade‚ climate changes‚ El Niño‚ and the increase in greenhouse gasses are being discussed more as earth friendly groups are trying to make the public aware of the negative situations the earth is facing. What would happen to the hydrologic cycle if the earth’s climate continues to get hotter? Is it too late to change humans’ patterns of behavior and

Carbon Cycle Living organisms are significant in the recycling of numerous elements contained in an ecosystem. One of the elements is carbon. Carbon is nonmetal‚ forms over ten million different compounds‚ found in minerals‚ oceans‚ and is the main component of biological compounds. So how do living organisms and their biochemical reactions contribute to the recycling of carbon? Carbon moves through the ecosystem in a cycle‚ in which the living organisms take and release

There are four stages of sleep‚ stage 1 occurs when the person decides it’s time to fall asleep. Initially in stage 1 alpha waves start waxing and waning bursts of 8-12 Hz’s EEG. This is when we are alert at our wake fullness. Stage one sleep RRG is low voltage but high frequency signal. As the stages progress into stage 2 there’s a gradual increase in EEG voltage and decrease in EEG frequency. Stage 2 has a higher amplitude and lower frequency and also has two wave forms‚ k complexes and sleep spindles

THE ROCK CYCLE ● ● ● ● There are three main types of rocks: igneous‚ sedimentary‚ and metamorphic. Each of these types of rocks are formed in different ways and each type of rock can be changed into the other types of rock. This process is called the Rock Cycle. The rock cycle is the process that makes and recycles rocks. IGNEOUS ROCKS ● ● ● ● ● ● Igneous rocks are formed from magma. Magma cools and solidifies into rock. When igneous rocks are exposed on the surface‚ time and weather break the
