During the last century‚ nuclear power has been established as a reliable source of energy in the major industrialized countries. Nuclear power plants provide about 17 percent of the world’s electricity. In the United States‚ nuclear power supplies about 15 percent of the electricity overall. Although no new plants are scheduled to be built in the United States‚ nuclear power is growing to be a popular producer of power. It has recently enjoyed a revival in attention and research due to the environmental

Abstract: The objective of the experiment is to learn how to use a microscope while viewing various types of bacteria cultures. Prepared slides are used to view bacterial cultures under a microscope that would normally be invisible to the naked eye. Bacterial shapes and arrangements or morphology are observed in prepared slides and fresh yogurt culture. Purpose: The experiment is meant to determine the shapes of bacteria under different magnifications when using a microscope; 10X‚ 40X‚ and 100X
