Answer:
They can use the host cell to copy themselves and make viral proteins
Explanation:
Viruses are organisms that are incapable of replicating on their own without infecting a living host. They use the host's ability to transcribe, translate and replicate to replicate themselves and translate their genetic material into proteins. The infection cycle represents their reproductive cycle.
Viruses infect their host cell by initially binding to specific receptors on the host's cell membrane. Then, they enter the host cell and incorporate their genetic material into the host's genome. They, then, use the replicational ability of their host to produce many virions and make proteins.
Answer: Soil carries out a range of functions and services without which human life would not be possible. It provides an environment for plants (including food crops and timber wood) to grow in, by anchoring roots and storing nutrients. It filters and cleans our water and helps prevent natural hazards such as flooding.
