Global Warming Introduction In this week’s assignment, we will discuss the composition of the earth’s atmosphere and possible effects on climate change/global warming by answering the following questions. First what are the current global carbon dioxide (CO2) concentrations? Then we will compare current CO2 numbers and see if this is higher or lower than the past 450,000 years? Next what are the three main ways that humans add CO2 to the atmosphere? What 'sinks ' take CO2out of the atmosphere?…

Opening the doors with a sudden breeze, automatically inhaling the smell of rubber, glancing to the left a large bulky man tells me to come over asking numerous of personal questions. Measuring my weight and BMI, I was over-weight. Coming home finding a book called Skinny Bitch by Kim Barnouin, reading cover to cover I found the answer to my weight problems, the word vegetarian popped out immediately. Researching online finding a YouTuber named Freelee the Banana Girl, explaining in each of her…

I have no name. I am Homo sapiens sapiens, and I 've helped develop our culture. I have lived through many dark times, known to you as nights. I have no formal written language and am able to be equal in cognition and articulation as you, though this does not hold true for me in my time. My life here is during the time you refer to as the "Paleolithic” period. This is the earliest t and longest age of the Stone Age, lasting from c. 1, 5000,000 to c. 8000 B.C. We actively developed and utilize…

Due to its extensive anti-corrosive properties, zinc plays an important role in the automobile industry and in construction. Therefore, the majority of extracted zinc (about 55%) is used to galvanize other metals, like steel and iron, in order to prevent rusting (Dayah, 1997). Zinc-coated, or galvanized, steel is used in the bodies of cars, steel bridges, lamp posts, on roofs, fencing, guard rails, and a variety of other metal structures (Royal Society of Chemistry [RSC], 2016)…

When looking at artifacts that point to early civilization, not much looks like anything we use today. With our mighty gadgets and volatile computers, it is hard to be terribly impressed by a moon shaped stone tool that is the size of a thumb nail. Moreover, when in context, artifacts like simple stone tools are really very innovative. However, in reality, it is difficult to relate them to our modern technological world, and in turn, it is hard to appreciate them. The one exception to this rule…

feature animals, abstract forms, and hand shapes. Lamps would illuminate the cave, paints were stored in stones and shells, and scaffolds could be made for access to new areas.

In the Pech-Merle Cave, stones were set up as an altar before Two Spotted Horses with Hands, and in Chauvet Cave a bear skull had been placed on a rock outcrop. Other than…

such as damage to vegetation, harm to the atmosphere, and harm to human beings. What is the impact of the air pollution in Mexico? Incomplete of fuels contributes to higher levels of gases such as carbon monoxide, ozone, sulfur dioxide, and nitrogen oxides-pollutants that harm eyes, lungs, and the heart. In addition, these gases, along with chemicals from factories, mix with water droplets in clouds and fall as acid rain. To reduce all this air pollution, the city promotes public transportation…

order to later determine pure copper content. Copper ore can be found in a mineral that contains pure copper and other species that is mined and can later have copper extracted from them (Taher, 1999). To eliminate all interfering species, such as Iron, Arsenic, and Antimony, from a sample of unknown copper ore one can use chemical reactions to eliminate interfering species by reduction and oxidation, and complex formation. Interfering species must be eliminated because they will react with…
