Answer:
1. Non-living
2. Reproduce
3. Nucleic acid
4. RNA
5. Protein
6. Capsid
7. Burst
8. Lytic
9. Lysogenic
Explanation:
Viruses are set of organisms classified as NON-LIVING (1) because they do not exhibit the characteristics that living things exhibit. Viruses are incapable of REPRODUCING (2) on their own, and hence, need a living host to infect in order to replicate itself.
In the structural composition of a virus, it is made up of only one type of NUCLEIC ACID (3), which can either be DNA or RNA (4). The nucleic acid is surrounded by a PROTEIN (5) coat called CAPSID (6).
There are two ways a virus can infect its host. First, it can replicate itself causing the host cell to BURST (7) or lyse in a process called LYTIC CYCLE (8). Also, the virus can remain dormant in the host cell and continually replicate with the host cell in a process called LYSOGENIC CYCLE (9).
