Answer:
Processes involving dissolved and particulate organic carbon are of central importance in shaping the chemical character of seawater. Marine organic carbon principally originates in the uppermost 100 metres of the oceans where dissolved inorganic carbon is photosynthetically converted to organic materials.

Answer:
Contaminación por quema de combustibles fósiles en vehículos, deforestación y uso de químicos en agricultura.
Explicación:
La contaminación por quema de combustibles fósiles en vehículos, la deforestación y el uso de químicos en la agricultura son los factores que generan problemas ambientales en nuestra comunidad. La quema de combustibles fósiles en vehículos e industrias libera gas de dióxido de carbono que aumenta la temperatura del área, la tala de árboles para uso doméstico tiene un efecto negativo en el medio ambiente. En nuestra comunidad, los productos químicos se utilizan para obtener una mayor producción que también contaminan los cuerpos de agua y los animales acuáticos afectados.
Answer:
directional selection
Explanation:
Directional selection is the most common type of natural selection and occurs when some individuals with characteristics favorable to the conditions of the environment in which they live, have survival advantages over individuals who do not have this advantage, who end up dying.
Imagine, for example, a graph showing the directional selection in the same species of moths. Moths of the same species have white and brown collations, in summer, brown moths can camouflage themselves on tree trunks, while white moths cannot and are easily captured by their predators, which means that the amount of white moths decrease. In this graph, the population of white moths would be at a minimum, at the same time that the population of brown moths would be at maximum.
However, with the arrival of the reverse, snow begins to cover the trees, allowing white moths to camouflage themselves more easily. The brown moths, then, are very exposed to predators, causing their population to reach the minimum while the population of white moths reaches the maximum.
