Question

which of these describes a difference between viruses and cells?
cells contain protein ,and virus contain only carbohydrates
viruses have flagella, cells have only cilia.
cells reproduce independently , viruses require a host to reproduce.
viruses have membranes made of proteins, and cells have membranes made of nucleic acid

Explanation:

Cells are living entities that can reproduce independently through processes like mitosis or meiosis. Viruses are non - living infectious agents that lack the machinery to reproduce on their own and need a host cell to replicate. Viruses and cells both contain proteins, neither viruses have flagella nor cells have only cilia, and cell membranes are made of lipids and proteins, not nucleic acids.

Answer:

Cells reproduce independently, viruses require a host to reproduce.
