Answer:
c. Bacteria can rotate 360 degrees
Explanation:
Bacterial flagellum is a long lash-like organ involved in locomotion of bacteria, but it can also have sensory function. Flagellum is made up of the protein flagellin that forms a shape of hollow tube. Flagellum can move in both directions, clockwise and counterclockwise. Rotation of this structure is possible thanks to motor proteins located at the flagellum's anchor point on the inner cell membrane.
