Which image is a correctly labeled prokaryotic cell?

The correct answer will be-the pic with long flagellum and small pili surrounding the bacteria

Explanation:

A bacteria is considered a prokaryote on the basis of its structure. The bacterial cell contains loosely arranged DNA freely floating in the cytosol instead of a nucleus.  

The surface of the bacteria contains the plasma membrane extension called pili which helps attachment to the substratum and the long flagellum sued for locomotion. The ribosomes are the small circular units for translation which freely floats in the cytosol.

These structures are correctly labelled in the attached figure and thus, the attached figure is the correct answer

the answer to your question is b

the darker peppered moth species were favored due to the fact that the industrial revolution had made all the nearby trees a darker color instead of white.
