Explanation:

For part b, the structure is for locomotion enabling bacteria to move. For part c, the absence of the structure in other bacteria might mean those bacteria are non - motile or have alternative ways of movement or don't need to move actively in their environment.

Answer:

b. The purpose of the structure is for locomotion to help bacteria move in their environment.
c. The absence of the structure might imply the bacteria are non - motile or have other movement mechanisms or don't require active movement in their habitat.
