The correct answer is the inner cytoplasmic membrane. Prokaryotes do not have mitochondria or any other membrane-enclosed organelles, but the electron transport chain must be performed in a membrane in order to create a concentration gradient of protons; therefore, prokaryotes perform the redox reactions of the electron transport chain in the inner cytoplasmic membrane in between the cytosol and the periplasmic space.

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.

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.

The correct answer is the "nucleus." Prokaryotes generally do not have membrane-enclosed organelles, and they do not have a nucleus. Plasmids are found in all prokaryotes, as well as in fungi. The other structures are found in both prokaryotes and eukaryotes.

This question examines your ability to read a graph correctly. The optimal concentration of YTSS for bacterial growth is the concentration of YTSS in the dish that allowed for the most bacterial growth in 24 hours. Looking across the vertical bars, which represent bacterial growth in millimeters, the dish that had the highest amount of bacterial growth was the dish containing a concentration of YTSS with ~54mm. And so the optimal concentration of YTSS for bacterial growth must be YTSS.
