Mendel shows that dominant alleles always took over, while sometimes in the F2 generation recessive traits would come back. As you can see, f<span>rom the proportions of phenotypes in the offspring. Then, if given that the genes would be equal you would get 1/4 A, 1/4 B and 1/2 AB; but you often get 1/4 A and 3/4 B.</span>

Answer:
photochemical
hydrocarbon
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>
Decomposers are very important in our ecosystem, they are responsible for breaking down decaying bodies to transform into nutrients. Without decomposers, plants will not be able to get enough nutrients that it needs to grow
