Division of labor is essentially when tasks are divided and carried out by specific parts. This occurs in cells, where different tasks are distributed among different parts, referred to as the organelles. For example, the mitochondria in the cell produce energy to carry out cellular activities. The nucleus is involved in cellular division and other genetic functions. In such a manner, the "labor" that a cell has to perform is divided among its organelles.
The changes will occur in an aquatic ecosystem as a result of nutrient loading are: changes in natural flow regimes as a result of water extraction and supply direct modification or destruction of important habitats barriers to the movement of plants and animals. For example within rivers and between rivers and their floodplain effects of poor water quality competition from introduced, <span>exotic animal and plant species. </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>
