• Virus because it has a nucleus.

• Prokaryotic cell because it has a nucleus.

• Eukaryotic cell because it has a nucleus.

• Eukaryotic cell because it does not have a nucleus.

A staph infection is caused by the bacteria, Staphylococcus aureus. S. aureus has a diameter of 2 micrometers (µm). What type of microscopic object is S. aureus?

• Virus, because it is a bacteria, and is harmful to people.

• Virus, because it is unicellular, doesn't have a nucleus, and is so small it's measured in micrometers.

• Eukaryotic cell, because it is harmful to people, and doesn't have a nucleus.

• Prokaryotic cell, because it is unicellular, doesn't have a nucleus, and is large enough to measure in micrometers.
