which best explains why viruses do not have special structures or enzymes that allow them to make their own food?\nviruses can use energy of living cells that they infect.\nviruses can replicate inside a host that they infect.\nviruses can cause contagious illnesses in host cells.\nviruses integrate their rna or dna into infected cells.
Answer
Brief Explanations:
Viruses are non - living entities outside a host cell and rely on host cells for energy and other life - processes. Since they can use the energy of the living cells they infect, they don't need special structures or enzymes to make their own food. Replicating inside a host, causing illness, and integrating genetic material are other characteristics but not related to food - making.
Answer:
Viruses can use energy of living cells that they infect.
