What prediction can you make about the impact of these threats on the resident populations versus the transient populations?
Mariulka [41]

Answer: A) The resident populations are more likely affected by these threats because of their proximity to shore.

Explanation:

All of these threats are higher in coastal regions.

As contaminants usually reach the ocean through rivers or because of coastal cities, the highest degree of pollution is there. All chemicals will accumulate in this region first, before they disperse into the offshore region. This is also caused by the fact that the coastal waters have a lower volume and surface area than the offshore which results in a higher degree of contamination.

How are global warning and El Nino similar? Is it possible to use effects of El Niño as evidence of potential dangers of global

El Niño as evidence of potential dangers of global warming to marine ecosystems

Explanation:

El Nino, an abnormal type of weather pattern, causes huge climatic variations globally by bringing floods in one region and drought in another region. These extremely changing patterns in weather can damage human life, agriculture, air quality, natural ecosystems, etc all of which might lead to global warming.  

El Nino effect is a serious potential danger to the marine life. This causes variations in the sea surface temperature, ocean currents, and upwelling patterns. Due to this, many marine organisms either migrate to newer places or do not survive the change.

Due to this, other sea animals depended on them also are depleted of their food source. El Nino also impacts the structure of coral reefs causing coral bleaching which in turn affects the marine life.

Discuss 3 different types of mutations that can happen
Brums [2.3K]

Answer:

Explanation:

Un cambio en la secuencia de bases en el ADN o ARN se conoce como mutación . ¿La palabra mutación te hace pensar en ciencia ficción y monstruos con ojos de insecto? Piensa de nuevo. Todos tienen mutaciones. De hecho, la mayoría de las personas tienen decenas o hasta cientos de mutaciones en su ADN. Las mutaciones son esenciales para que ocurra la evolución. Son la fuente principal de todo el material genético nuevo -nuevos alelos - en una especie. Aunque la mayoría de las mutaciones no tienen efectos en los organismos en que ocurren, algunas mutaciones son beneficiosas. Incluso las mutaciones dañinas rara vez causan cambios drásticos en los organismos.
