Question

a student lists several characteristics of viruses in a table. which characteristic(s) differentiate(s) viruses from cells? 1. they contain nucleic acid. 2. they lack cytoplasm and cellular structures. 3. they are microscopic. 4. they use hosts enzymes and cellular structures to reproduce. 1 only 2 only 1 and 3 2 and 4

Explanation:

Cells have cytoplasm and cellular structures and can reproduce independently without relying on host - cell machinery. Viruses lack cytoplasm and cellular structures (characteristic 2) and use host's enzymes and cellular structures to reproduce (characteristic 4). Both cells and viruses can contain nucleic acid (characteristic 1) and be microscopic (characteristic 3).
