Answer:

I believe that the answer would be: Evolution of the fruit fly over time (A)

Explanation:

As we can see, the fruit fly shown is the only fruit fly we are observing. Therefore, we need to determine how it has different cells among other cells. This is where evolution would come into the picture. The reason this fruit fly has different cell structures and functions is because, over time, their bodies and makeup have changed, leaving behind these "older" cells that are now dominated by the newer ones. So, evolution is the reason why the fruit fly has different cell structures and functions.

Just like how us humans have wisdom teeth in our mouths that are not necessary because our mouths have evolved to be smaller; there isn't enough room for them to grow, in some cases.

I hope this helps! :)) Have a good night!
