Explanation:
Viruses are pathogenic microorganisms that lack the ability to thrive and reproduce outside of a living host cell. Their structure is simple - they consist of a nucleic acid molecule surrounded by a protein coating and sometimes an outer envelope. They are too small to be seen by a light microscope.
As they are way smaller than living cells, viruses are smaller than organelles as well. They don't have their own metabolism. Their reproduction is not based on division. They don't have any organelles, including the cytoplasm. They are surrounded by a protein coat called the capsid.
Based on this information, we can see that the correct statements are statements 1, 2, and 5.
