respiratory and cardiovascular systems in maintaining the body’s internal balance Both the cardiovascular and respiratory systems are jointly essential for a particular purpose - delivering oxygen to our bodies, and for extracting and expelling carbon monoxide from them (Dr Adam Cloe, livestrong.com/article 18606, 2011). “The cardiovascular system…consists of three interrelated components: blood, the heart, and blood vessels, respectively (Tortora & Derrickson 2011). The heart pumps blood throughout

increased the amount of carbon dioxide gas emitted to the atmosphere and the amount that dissolves into the ocean. Now, so much carbon dioxide has been absorbed by the ocean that the chemistry of seawater is changing, causing the ocean to become more acidic. THE CARBON CYCLE Carbon dioxide is a critical part of Earth’s atmosphere; it traps heat and prevents the Earth from being covered in ice. Normally, the Earth’s carbon cycle maintains a natural balance of carbon in the atmosphere, land,

which type of animals and plant life will live in that area as well. Carbon function in the ecosystem is to be used by the plants for photosynthesis and to make organic molecules (Slideshare.net 2012). It is pulled from the atmosphere and used to become stored food. Animals eat the plants and then their digestive system breaks down the food to release energy and when breathing they release carbon dioxide out and continues the cycle. Nitrogen is in four phases, fixation, decay, nitrification and denitrification

The citric acid cycle — also known as the tricarboxylic acid cycle (TCA cycle), or the Krebs cycle,[1][2] — is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetate derived from carbohydrates, fats and proteins into carbon dioxide and chemical energy in the form of adenosine triphosphate (ATP). In addition, the cycle provides precursors of certain amino acids as well as the reducing agent NADH that is used in numerous other biochemical reactions

Marcus McClenty W. Steward Environmental Issues EG481 22 February 2015 Outline: Is Climate Change Manmade? Hypothesis: Climate change is not manmade. The climate is changing, the globe is warming, both these terms express an action is taking place. Why are these actions taking place? Are these actions caused by man or nature? Is the correct terminology being used when describing this phenomena? These are just a few questions that will be explored in this report. The term global warming is

what are its three stages? Cellular respiration is the process by which electrons are transferred between glucose to coenzymes and then to oxygen and turns it into energy called ATP used by cells. The three stages are: 1) glycolysis 2) citric acid cycle 3) electron transport. What is the role of glycolysis? Include the reactants and the products. Where does it occur? The role of glycolysis is to split a molecule of glucose into two molecules to form a compound called pyruvic acid from enzymes located

remediate these fragile ecosystems. One such ecosystem is located in the Southeast desert of California, the Algodones Dunes. Although sand dunes are not a typical or popular ecosystem, they do have structural dynamics, human affected biogeochemical cycles, a need and plans for management, and implications of species interactions in that management. Structural Dynamics The Algodones dunes is a band of sand dunes reaching as high as eighty meters that extend seventy five kilometers in length from
