Renewable Energy Source

Help in Biology Pleaseeee!?
I will tell you what I think the answers are, and you can tell me if they are right or wrong and if they are wrong please help me in finding the right answer. I really appreciate the help! 1. Which of the following best describes the long-term impact of using a renewable energy source? A.Geothermal energy can pollute water supplies. B.Hydropower involves blocking rivers, which disrupts ecosystems. C.Natural gas causes air pollution when burned. D.Nuclear power produces radiation, which is harmful if leaked. My answer for this question is B but C and D make sense too? So which would be best?? 2. Which of the following best describes a benefit of one type of nonrenewable energy? A.Coal is relatively inexpensive compared to other forms of energy. B.Natural gas does not produce greenhouse gases as other energy sources do. C.Nuclear power does not produce any form of pollution. D.Petroleum can be found nearly anywhere and is easily extracted. My answer to this question is C? 3. Which of the following best describes what happens to water molecules after they are released from plants through transpiration? A.They will combine to form runoff and flow into rivers, lakes, and oceans. B. They will cool and form dew, clouds, or fog through condensation. C.They will fall to Earth in the form of rain, sleet, or snow. D.They will undergo evaporation and change to a gas. My answer for this question is B???? 4. Which of the following best describes environmental parameters that should be examined before a city can build a landfill? A. How close the landfill will be to major cities and highways B. If leakage from the landfill will be able to contaminate groundwater C. What the costs involved in maintaining the landfill will be D. Whether there will be sufficient staff available to operate the landfill My answer for this question is B?? 5. Scientific research shows that our global climate is changing. Ocean temperatures and acidity are increasing, and the global sea level is rising. Which of the following best predicts an outcome of this global climate change in a marine ecosystem? A.Many marine species will not be able to adjust quickly enough to survive. B.More species will be able to survive due to the less extreme temperatures in the ocean. C.Tectonic plate activity will increase and produce warmer ocean temperatures. D.The increased acidity will make it more difficult for harmful bacteria to survive. My answer to this question is D??? 6. Which of the following is the best example of a way human lifestyles affect environmental systems? A.Agriculture causes water pollution when fertilizers and pesticides flow into lakes and rivers. B.Burning fossil fuels causes air pollution by decreasing water vapor in the atmosphere. C.Using aerosol sprays causes acid rain by increasing ozone (O3) in the atmosphere. D.Using radioactive materials causes ground pollution when chlorofluorocarbons (CFCs) seep into the ground. My answer to this question is C???? 7. Domestic cats can begin reproducing as young as six months of age. Each female cat can produce two litters per year, containing multiple cats that can also begin reproducing early. What prediction can you make about an ecosystem in which cat populations are not controlled? A.A predator for the cats would rapidly appear to match the population growth. B.Small game would initially suffer but then quickly develop survival skills. C.Within a few years the population of cats would increase slowly, level off, and stabilize. D.Within a few years there would be many starving cats. My answer to this question is A??? 8. Every year, millions of acres of land are cleared by uncontrolled forest fires. Which of the following best describes a consequence of these catastrophic events? A.Biodiversity will increase as new species move into the cleared area. B.Invasive species will quickly take over the disturbed area. C.Oxygen levels decrease rapidly in the areas near the fire. D.Only the plants that benefit from fire will survive. My answer to this question is A???

What are the Five Renewable Energy Sources?
so i have this report due tomorrow and i have to tell why i chose a specific renewable energy. i chose wind energy because i already did a presentation in class about it. so the first paragraph was why did i choose wind energy. now the second is what i am having trouble with. its why did you choose this renewable energy. well this is my exuse for each one: solar: it isnt always sunny hydroelectric: causes fish displacement nuclear: can cause nuclear waste so basiclly i just need the other energy. here are the ones i know: solar wind hydroelectric nuclear could you please help me out with the last one? thank you!!!
