SOVA2 [1]

Answer:

la selección natural es el mecanismo principal por el cual la evolución ocurre

Explanation:

Charles Darwin fue un naturalista inglés que propuso la teoría de la evolución o 'descendencia con modificación' mediante el mecanismo de selección natural. Acorde a esta teoría, la selección natural se define como el mecanismo selectivo de reproducción diferencial de los individuos mejor adaptados a su ambiente. La variabilidad es el la materia prima sobre la cual la selección natural actúa, seleccionado aquellos individuos que presentan combinaciones fenotípicas y genotípicas más adaptadas para sobrevivir en un ambiente en particular. Los individuos de una población que son 'superiores adaptativamente' poseen más chances de sobrevivir y reproducirse, y por lo tanto tienen también más probabilidades de transmitir sus genes a la siguiente generación.

Is Solid waste point source pollution or non point source pollution?
Yanka [14]

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.
