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.

Answer:
I think it's C. hope that helps
Answer:
Option (4).
Explanation:
Corpus callosum is also known as callosal commissure. This area is present beneath the cerebral cortex of the brain. Corpus callosum is present in placental mammals only.
The corpus callosum connects the left and right side of body.The severed or improper functioning of corpus callosum may disturb the coordination of action and speech of the right and left side of body.
Thus, the correct answer is option (4).
