Explanation:
Place theory is a theory of hearing which declares that our judgment of sound depends on where each element frequency generates oscillations along the basilar layer. According to the frequency theory, the pulse rate of the nerve vibrations of the hearing nerve communicates to the rate of a pitch, which enables us to identify its pitch. The complete basilar layer is stimulated by sound waves at various frequencies.
Air pollution refers to the release of pollutants into the air that are detrimental to human health and the planet as a whole.
The Clean Air Act authorizes the U.S. Environmental Protection Agency (EPA) to protect public health by regulating the emissions of these harmful air pollutants. The NRDC has been a leading authority on this law since it was established in 1970.
What Causes Air Pollution?
“Most air pollution comes from energy use and production,” says John Walke, director of the Clean Air Project, part of the Climate and Clean Air program at NRDC. “Burning fossil fuels releases gases and chemicals into the air.” And in an especially destructive feedback loop, air pollution not only contributes to climate change but is also exacerbated by it. “Air pollution in the form of carbon dioxide and methane raises the earth’s temperature,” Walke says. “Another type of air pollution is then worsened by that increased heat: Smog forms when the weather is warmer and there’s more ultraviolet radiation.” Climate change also increases the production of allergenic air pollutants including mold (thanks to damp conditions caused by extreme weather and increased flooding) and pollen (due to a longer pollen season and more pollen production).
Answer:
Energy is another word for "calories." Your energy balance is the balance of calories consumed through eating and drinking compared to calories burned through physical activity. ... People who are more physically active burn more calories than those who are not as physically active.
