Answer:
Nonpoint-source pollution is the opposite of point-source pollution, with pollutants released in a wide area. As an example, picture a city street during a thunderstorm. As rainwater flows over asphalt, it washes away drops of oil that leaked from car engines, particles of tire rubber, dog waste, and trash. The runoff goes into a storm sewer and ends up in a nearby river. Runoff is a major cause of nonpoint-source pollution. It is a big problem in cities because of all the hard surfaces, including streets and roofs. The amount of pollutants washed from a single city block might be small, but when you add up the miles and miles of pavement in a big city you get a big problem.
In rural areas, runoff can wash sediment from the roads in a logged-over forest tract. It can also carry acid from abandoned mines and flush pesticides and fertilizer from farm fields. All of this pollution is likely to wind up in streams, rivers, and lakes.
Airborne pollutants are major contributors to acid rain. It forms in the atmosphere when sulfur dioxide and nitrogen oxides combine with water. Because acid rain results from the long-range movement of those pollutants from many factories and power plants, it is considered nonpoint-source pollution.
Explanation:
In biology, a life cycle<span> is a series of changes in form that an </span>organism<span> undergoes, returning to the starting state. "The concept is closely related to those of the </span>life<span>history, development and ontogeny, but differs from them in stressing renewal."</span>
B - Homozygous, because both alleles are the same
<span>The difference that you are searching for is the addition of Appendages. They appeared in Cambrian animals and were used to increase their physical capabilities like when sensing and processing the information found in the environment. Common appenadges found in animals are things like antennae found in insects that are used to help them communicate or notice things or similar things.</span>
