Example Questions
Example Question #1 : Viruses
Which of the following is true about viruses?
Viruses will immediately infect any living thing, and are unable to be removed.
Viruses consist of a nucleus, cell membrane, and several mitochondria in order to make their own energy.
Viruses are considered to be non-living organisms.
Viruses reproduce via sexual reproduction.
Viruses are considered to be non-living organisms.
Viruses are considered non-living organisms because they have no organelles or other cellular machinery, they cannot reproduce without a host cell, and they have no metabolic activity.
Example Question #2 : Viruses
Viruses can do which of the following?
Reproduce outside of a cell
Respond to outside stimuli
Carry DNA
Metabolize chemical compounds
Produce proteins
Carry DNA
All viruses can and must carry either DNA or RNA (but not both). However, viruses cannot reproduce on their own, and must infect a host cell in order to manufacture more copies of itself. They cannot respond to outside stimulus as they do not have any functional parts, such as mitochondria, ribosomes, or a nucleus. For the same reason, viruses also cannot produce proteins or metabolize chemical compounds.
