Answers:please do not abuse yahoo answers this is your school work and you need to learn how to do it by yourself, or else you wont learn anything and environmental science is an easy class

Answers:a Biome is based on the vegetation structure found in different parts of the world is similar in similar environments, usually based on climatic conditions. The closest answer to this would be A. C A D D D B

Question:I have a question about environmental science....... 1. A good example of source reduction would be: A: Burning old tires to create usable energy. B: Finding uses for discarded computers. C: The lighter weight of aluminum cans as opposed to years ago. D: Installing air pollution control devices in incinerators. E: Increasing the percentage of paper, glass, and aluminum that is recycled in the U.S. In my book it says the source reduction is a strategy where industries can often design and manufacture their products in ways that decrease the volume of solid waste and the amount of hazardous materials in the solid waste stream. It also says that it is the most underutilized aspect of waste management and that it is accomplished in a variety of ways, such as substituting raw materials that introduce less waste during the manufacturing process and recycling and reusing wastes at the plants where they are generated. I just don't comprehend the question. I don't think the answer is B or D but correct me if I'm wrong. Can you please give me a detailed explanation of the answer as well. Thank You So Much B doesn't make since. Because the definition of source reduction states that it is all about reducing waste at the source of the product when it is made. Not after it has already been made.

Answers:B finding uses of a discarded computer. Since, today computers are being used extensively in every field its better to find the uses for them and computers are being discarded heavyly.

Question:I am preparing for an exam in my Environmental Science class and am stuck on a couple of the questions presented on the study guide. If you have any experience with this type of coursework, I would definitely appreciate your assistance! The questions are as follows: *Which of the following would have the greatest contribution to reducing consumption of crude oil? A) Using wind power to produce electricity B) Providing better insulation in buildings C)Designing appliances with greater energy efficiency d) Switching from coal to nuclear energy to produce electricity E) Making cars with greater fuel efficiency (I am thinking that it is A or D...not sure) *Which of the following environmental impacts is common to both coal-fired and nuclear power plants? A) Release of sulfur oxides B) Release of high levels of radioactive materials C) Extensive thermal pollution from the use of surface waters to remove waste heat D) Release of CO2 E) Disposal of high level radioactive wastes (I think the answer may be B or E, but again, I'm not sure...) 15) Which of the following is true concerning the energy in coal used to produce electricity? A) It cannot be used for any other purpose B) It is the only fuel that can be used to produce electricity C) Little energy is lost as heat in the production of electricity D) Most of it is converted to electricity E) Most of it is dissipated in the conversion to electricity Thank you so much!!!

Answers:Q1: E (Oil is rarely used for electricity production. It is mostly consumed as a fuel for vehicles etc.) Q2: C (Both types of power plants use water for cooling. Nuclear power plants don't release Sulfur Dioxides, do not release high levels of radioactive materials [they are stored safely - it is illegal to allow it to be released], nuclear plants don't release CO2, and Coal plants do not safely dispose of their radioactive wastes - it gets burnt into smoke and ash because it is mixed in with the coal when it is burned) Q3: E (Burning Coal to heat steam in order to drive turbines produces a lot of unused heat as a by-product - hence thermal pollution, as mentioned earlier. So much of the energy from coal is dissipated as waste heat)
