Question

question 1 - 2
which of these describes a difference between viruses and cells?
cells contain protein, and viruses contain only carbohydrates.
viruses have flagella, and cells have only cilia.
cells reproduce independently, and viruses require a host to reproduce.
viruses have membranes made of protein, and cells have membranes made of nucleic acid.

Explanation:

Cells are living entities that can reproduce on their own through processes like mitosis or meiosis. Viruses are non - living entities in the sense that they lack the cellular machinery to reproduce independently and must use a host cell's machinery for replication. The first option is incorrect as viruses contain proteins and nucleic acids, not just carbohydrates. The second option is wrong because viruses do not have flagella and cells can have both flagella and cilia. The fourth option is incorrect since cell membranes are made of lipids and proteins, and viruses do not have true membranes in the same sense as cells.

Answer:

Cells reproduce independently, and viruses require a host to reproduce.
