Answer:
after forming a hypothesis... the next step is to prove that hypothesis write or wrong by doing experiments
From what we know, we can confirm that Negative-sense single-stranded RNA viruses are thought to have arisen many times independently because the nucleotide sequences are not related.
<h3>What does this mean?</h3>
Nucleotide sequences are what make up the DNA of humans, or in this case, the RNA of the virus. Just as with humans, these sequences can be used to trace a lineage and see the relationships between the various kinds of viruses. These studies showed that the viruses are not related.
Therefore, since the nucleotide sequences of these viruses did not match, scientists were led to believe that Negative-sense single-stranded RNA viruses have arisen many times independently.

The answer is <span>a. chloroplast.
A chloroplast is the </span><span>cell organelle shaped like a flattened disc. It contains stroma and stacks of thylakoids. It is present in the cells of green leaves of the plants. It is important in the process of photosynthesis because it contains pigment chlorophyll. Chlorophyll is important for photosynthetic biochemical reactions that take place in chloroplasts.</span>
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.
