'C' is the correct answer. Viruses are considered nonliving because they are made of genetic material and proteins, but they lack the cellular structure that is characteristic of living organisms.
Explicação
## Step 1Viruses are unique entities that straddle the line between living and non-living. They possess genetic material (either DNA or RNA) and can replicate, but only within a host cell. This is because they lack the cellular machinery necessary for self-replication.## Step 2The statement "Viruses come from cells" is not a reason for considering viruses nonliving. While it's true that viruses are often found within cells, this is not the primary reason they are considered nonliving.## Step 3The statement "Viruses produce cells" is incorrect. Viruses do not produce cells; instead, they hijack the host cell's machinery to replicate their own genetic material.## Step 4The statement "Viruses are made of DNA and proteins, but not cells" is accurate. This is one of the primary reasons viruses are considered nonliving. While they contain genetic material and proteins, they lack the cellular structure that is characteristic of living organisms.## Step 5The statement "Viruses can contain one or multiple cells" is incorrect. Viruses are not made up of cells; they are acellular entities.
