Question

A thin piece of dome-shaped cuticle was found near one of the joints in a cricket leg. When it was removed, the animal could no longer make coordinated movements, but it could still respond to the rapid approach of a predator. This structure is most likely a_______

Answer 1

The structure most likely responsible for the cricket's loss of coordinated movements is the apodeme.

Step-by-step explanation:

The structure that is most likely responsible for the cricket's loss of coordinated movements after the removal of a thin dome-shaped cuticle near a joint in its leg is the apodeme. An apodeme is an ingrowth on the arthropod's exoskeleton to which muscles attach. Contraction of muscles attached to the apodeme enables coordinated movements. Thus, when the cuticle with the apodeme is removed, the cricket loses its ability to make coordinated movements.
