Explanation:
Morning commuter traffic in cities contributes to<u> photochemical</u> smog. In this type of air pollution, a mixing of <u>hydrocarbons</u> from certain plants, nitrogen oxides from cars, and UV radiation from the sun results in a variety of pollutants, such as ground-level ozone, which can cause coughing and breathing problems.
<em>Photochemical smogs are caused by the photochemical reaction of hydrocarbon and nitrogen oxides in the lower atmosphere with sunlight playing a major role. The reaction of the hydrocarbon with the nitrogen oxide in the presence of light leads to the evolution of ozone gas while nitrogen oxide has the capacity to react with the sunlight on its own to produce nitrogen dioxide. This result in the formation of smog</em>
They pollinate plants, which saves farmers work. Insects such as bees and butterflies help to pollinate plants.
First you must know that a diploid cell has double the amount of chromosomes of a haploid cell. A diploid cell has 46 chromosomes. When we divide 46 by 2 you get 23. This means that there are 23 chromosomes in a haploid cell.
