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:
The genetic code that living things have is found in a molecule called DNA.
Explanation:
DNA is a molecule of nucleic acid, responsible for containing all the genetic information of a living organism.
DNA forms a double strand that is found in the nucleus of eukaryotic cells or in the cytoplasm of prokaryotes, and the information is encoded in a specific nucleotide sequence, the translation of which allows the synthesis of proteins.
The information contained in each DNA molecule constitutes a chromosome, and the fragments of this molecule form the genes that determine specific morphological and functional characteristics.
Regarding the other options:
- <em>Cells</em><em> are the morphological and functional unit of living beings, and they contain the DNA.
</em>
- <em>Cytoplasm</em><em> is a fluid substance found inside the cells and serves as a support for the nucleus, organelles and other substances.</em>
Starting with the hardest it would be corundum, feldspar, apatite, calcite, talc.
