Read the passage about the influenza virus.
The influenza virus is one of the most common infectious diseases affecting humans. A virus is made of tiny particles called
virion. Virion contain enveloped, single-stranded genetic information. They are between 80 to 120 nanometers in diameter.
Once inside of a host cell, virion begin replicating during an incubation period of one to four days. After the incubation period,
humans begin to feel the symptoms of the influenza virus. Each year, millions of Influenza A and B vaccines are administered
in the United States. The vaccines contain antigens from the strains that are most likely to cause illnesses. New vaccines are
needed every year because viruses constantly change during replication.
Using the information in the passage, which statement best supports the idea that a virus is similar to a living organism?
A)
