Gas Exchange To complete this worksheet‚ select: Module: Gas Exchange and pH Balance Activity: Animations Title: Gas Exchange Introduction 1. a. Describe the respiratory system role with oxygen and carbon dioxide. The respiratory system is responsible for the movement of gases involved in cellular metabolism. b. Why is oxygen needed? Oxygen is needed because it is used up during the aerobic breakdown of glucose. c. What generates CO2? Carbon dioxide arises from the aerobic

The Five Platonic Solids The five platonic solids are the tetrahedron‚ cube‚ octahedron‚ dodecahedron‚ and a icosahedron. They are named for the greek philosopher Plato. Plato wrote about them in the Timaeus (c.360 B.C.) in which he paired each of the four classical elements earth‚ air‚ water‚ and fire with a regular solid. Earth was paired with the cube‚ air with the octahedron‚ water with the icosahedron‚ and fire with the tetrahedron. The fifth Platonic solid‚ the dodecahedron‚ Plato says that

Analysts expect gas prices to decrease or remain mostly flat not only in 2014‚ but for years to come. Nonetheless‚ drivers in some states will see higher prices at the pump‚ starting January 1. Gas prices may not have seemed all that cheap in 2013. But in fact‚ prices for the year as a whole were less expensive than they have been. According toAAA’s year-end report‚ American drivers paid $3.49 per gallon of regular‚ on average for 2013. That’s the cheapest per-gallon average since 2010; the national

Cindy Hoang-Tran Professor Ducat English 101 13 Dec 2012 Gas Fracking Natural gas is extremely useful in our lives. We need natural gases to heat our houses and use microwave ovens‚ conventional ovens and stovetops. Because the economy currently isn’t well off – and hasn’t been recently – natural gases are now in higher demand for cheaper prices. Oil and gas drilling facilities are now making it possible for natural gases to be sold at extremely cheap prices and accessible amounts through the
