Answer:
They do not make their own membranes.
They have, at most, one or a few enzymes.
They do not have both DNA and RNA.
They do not have cytoplasm or ribosomes.
They are much smaller than most cells.
They cannot replicate on their own.
Explanation:
Viruses are obligate parasites and are considered acellular since they do not have the basic cell structure. Being an acellular structure, viruses lack membranes, organelles, ribosomes, cytoplasm, etc. Viruses lack their own metabolic machinery, that is, they do not have their own enzymes to replicate themselves. They enter the host cells and use the enzymes of host cells to replicate themselves. Viruses have a genome (either DNA or RNA) that is surrounded by a protein coat.
On the other hand, cells are much larger than viruses. Cells have a cell membrane that encloses liquid cytosol in which various organelles such as ribosomes are suspended. Cells have all the required enzymes for metabolism and can make their own membranes. They can replicate themselves. DNA in a cell is present in the nucleus while RNA is present in both nucleus and cytoplasm.
For the first question the answer is D. Systemic
For question number 2 the answer is B. Lungs
