The reproductive isolating mechanism most likely responsible for the divergence of bonobos and chimpanzees is ECOLOGICAL ISOLATION.
The ecological mechanism of reproductive isolation is also known as TEMPORAL ISOLATION or HABITAT ISOLATION. This includes the barrier for reproduction that leads to isolation such as different habitats or any physical barriers.
Answer:constriction of pupil
Explanation:the circularly arranged smooth muscle fibers in the highlighted structure ie the iris causes constriction of the pupil.
