Both nuclear power plants and the coal or natural gas power plants use steam to turn turbines to generate electricity. elaborate on why one might choose nuclear power over the fossil fuel power plants. a) isotopes contaminate the surrounding environment making it uninhabitable for people and animals. b) nuclear power has far less environmental impact than using coal or natural gas to produce electricity. c) radioactivity is the wave of the future and the only sustainable energy source currently available to us. d) radionucleotides used in nuclear power plants are very expensive and not cost effective compared to other fuels.

answer; i believe the correct answer is (anemia);

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
