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.

HELP I NEED A SCIENTIFIC MODEL AND PARAGHRAPH ABOUT ATOMIC THEROY WILL GIVE BRANLIEST AND POINTS
saveliy_v [14]

<h2>Atomic Theory:</h2><h2>Introduction</h2>

The atomic theory of Atoms Summed up is the idea that all matter is made of tiny particles that are imperceptible to the mortal eye; these particles are named Atoms

<h2>Paragraph 1:</h2>

John Dalton was the first to consider that all matter was made of tiny particles known as atoms. He invented the idea that matter is formed of atoms varying in weight.

<h2>Paragraph 2:</h2>

I created this model of the dissimilarities between three kinds of matter-- solids, liquids, and gases. The distance between atoms in each state tells us what type of matter we observe.

The Drawing is on the file

The End.

I hope you found this helpful
