incredibly cyclic, and have been studied to shift between periods of warm and cold temperature anomalies. Although the Earth cycles naturally on its own, it is evident that excessive emission production is enhancing the greenhouse effect, and therefore causing natural climatic shifts to happen at a faster rate. People are discernibly prone to assume that since Earth’s climate cycles naturally, that Global warming is autonomous of anthropogenic impact. Global warming is not the root of climate change,

ECOSCIENCE The Lithosphere The term Lithosphere is derived from Greek and means “rock layer. The lithosphere is approximately 65 to 100 km (40 to 60 mi) thick. Geologists regard the lithosphere as the relatively cool, outermost layer of the planet and view it as a rigid shell. The lithosphere is broken up into different plates. At a depth of about 100 km, the rigid, brittle rock of the lithosphere suddenly gives way to hot, soft, plastic rock of the asthenosphere. In this layer, rock is

usage of carbon dioxide and water. This process is called photosynthesis. After the process of photosynthesis, there comes the production of sugar. Animals are able to use sugars delivered by the plants in their individual energy storage called the mitochondria. The mitochondria produces a form of energy currency and it creates ATP (adenosine triphosphate). The ATP is a highly energetic molecule that supplies the vitality we need to get our bodies to function properly. The energy’s life cycle is powered

1. Lancaster City Tap Water vs. Dasani Bottled Water Lancaster City tap water is tested by the Environmental Protection Agency in order to hold standards of metals, chemicals, microorganisms, and byproducts to ensure safety of the consumer. On the other hand, Dasani bottled water is tested by the Food and Drug Administration for the same contaminants and both tests hold the same Maximum Contaminant Levels, with the exception of lead, where Dasani has lower MCLs for the substance. Dasani bottled

LABORATORY EXERCISE #1 Carbon Dioxide Emissions from Automobiles The reason we focus on CO2 is that emission of this gas changes the climate. Natural emission of CO2 is much greater than that produced by humans. The natural carbon cycle in nature absorbs much of the CO2 produced. However, vegetation and oceans only absorb about 40% of CO2 produced. In addition, human activities such as livestock production add significantly to the production of both CO2 and methane. So what are some of

into glycerol and fatty acids. The fatty acids then undergo beta oxidation. The fatty acid is activated by Coenzyme A which leads to the breakdown of the fatty acid into 2-carbon fragments called Acetyl-CoA. Acetyl-CoA moves on to the citric acid cycle. Electrons and hydrogens are removed from NADH and FADH-2 in the citric acid cycle and are carried to the electron transport system. NADH and FADH-2 also remove the electrons and hydrogens from the fatty acids and send them to the electron transport chain

The purpose of Carbon Tax – Pros and Cons Researchers have been attempting to estimate the monetary value of damages in future resulting from climatic change. This change is associated with a steady increase in carbon dioxide emissions in every given year hence resulting in an attached value of the benefit from commensurate reduction of the toxic emissions. This measure is usually known as the social cost of carbon (SCC). SCC has been estimated by a task force of the federal government

several differences between unsaturated and saturated fatty acids. Unsaturated fatty acid is made of carbon and hydrogen bonds that does not mix well with water. Unsaturated fatty acids are solids at room temperature. They are found in food sources such as cheese, red meats, coconut oil, whole milk dairy products. Unsaturated fatty acids are structurally designed with a single carbon of a single carbon double bond, and hydrogen bonds. They are liquids at room temperature. Unsaturated fatty acids include

are beta oxidation, the citric acid cycle, and the electron transport chain. A fatty acid is a long chain of carbons and hydrogens with a carboxylic acid group at the end. In beta oxidation, the fatty acid is broken down into two carbon units, which produce acetyl-CoA, and electrons and hydrogens are removed. The first step of beta oxidation occurs when the fatty acid is activated by the addition of a CoA subunit and the fatty acid is broken down into carbon units called acetyl-CoA and electrons

skeptics, well it is happening now. Representatives from countries all over the world will meet in July, 2011 to discuss slowing down global warming by setting the limits on the countries' greenhouse gases emissions, which include the emissions of carbon dioxide the industries, machines, and cars produced. (Reis, 2011). Despite of the current evidence of global warming, people still believe that this is something that is completely made up and blown out of proportion. Global warming has a direct
