In his essay “The Organic Fable‚” Roger Cohen argues that there is little to no difference between organic foods and regular foods. He says‚ “Organic has long since become an ideology‚” says it is branding‚ not science‚ and says we need genetically modified food anyway to feed more people. He also says it is an‚ “obsession of an upper middle class‚” and compares buying organic foods to‚ “paying to send your kids to private school.” I believe‚ though‚ that his argument is biased and inconsistent‚

1. What is Chemistry? The study of the composition‚ structure‚ and properties of matter. The processes that matter undergoes and the energy changes that accompany these processes. 2. What is the formula for density? If I give you the density of a substance and the volume‚ you should be able to tell me the mass… Density = Mass/Volume 3. Compare and contrast intensive and extensive properties. Give an example of each. Extensive properties depend on the amount of matter that is present. Such
