Geochemistry Pop Quiz 2 - 20/3/2013 Niall Smith - SF Earth Science 1) On what evidence is the statement “If current carbon dioxide emission trends continue, shells of marine organisms will start dissolving in some parts of the ocean sometime around mid-century” supported? Provide a short explanation and what you think are the two most relevant literature references illustrating your point. The scientific evidence which supports this statement originates from two distinct categorical sources

pyruvate. This anaerobic cycle that can occur in the presence of oxygen or not. It is used to release high energy compounds of adenosine triphosphate, ATP. Glycolysis takes one glucose and results in two three carbon chains of pyruvate, along with a net total of two ATP released. The Kreb, or Citric Acid, Cycle is series of chemical reactions used by aerobic organisms to generate energy following Glycolysis. The process between glycolysis and the start of the Kreb Cycle takes the pyruvate at the

because of human activities such as the burning of coal, oil, and natural gas” (Turk & Bensel, 2011). Levels of greenhouse gases in the atmosphere have increased substantially through the industrial revolution. In particular, the concentration of carbon dioxide in the atmosphere has increased by roughly 35 percent since

History Back in the 1840s, the presence of granule-like structures within muscle cells and other cell types were being recognized by several scientists. (Ernster and Schatz 1981) In 1890, Richard Altmann, who was a cytologist, used a dye technique to detect the granules and termed them as “bioblasts.” He speculated that they were the basic units of cellular activity. (Ernster and Schatz 1981) It was in 1898 when Carl Benda gave these bioblasts a new the Greek name “mitochondria” meaning thread

Cellular Respiration Class, today we are going to be talking about a really cool way your body breaks down food molecules into carbon dioxide and water! First, let’s understand what exactly this means. This process is called Cellular Respiration. This happens when food molecules, such as glucose (sugar in your body) breaks down into carbon dioxide, which is an odorless gas in the air, and water. And I’m sure you all know what water is, correct? (Giggle) That’s what I thought! Now that we all

Environmental Science Derick Stevenson AIU Online The grasslands of the world establish a major part of ecosystems in dissimilar areas of the world. The grasslands play a big part in parts of Africa, and also they have a lot of distinguishing properties. Grasslands inhabit almost all ecological regions and can be gathered into six groups. You have moderate grasslands, flooded grasslands, xeric and desert grasslands, and tropical and subtropical grasslands that can all be assembled into classes

and process the sun’s energy to make this energy available to all living things” (Educational Board [EB], 2012). Photosynthesis happens when the sunlight is captured by the chlorophyll, carbon dioxide enters through the stomata and water enters through the roots. Photosynthesis produces glucose and water. The carbon dioxide is produced by animals which breathe it out and the glucose, which is sugar, is produced by the process of photosynthesis. This production is helpful to both the plants and animals

skyrocketed over the past few hundred years. In other words this is anthropogenic climate change, and the significant increases in the atmosphere of these potent greenhouse gases are a result of human activity. The most potent of the greenhouse gases are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N20). Alarmingly, these are a result of anthropogenic climate change, and the gases are at the highest levels for over 650,000 years. Since 1750, it is estimated that about two thirds of anthropogenic
