Quizplus · Accepted Answer

The figure shows a structure that is characteristic of a statocyst. A statocyst is a sensory organ present in many invertebrates that helps them to maintain balance and orientation in space. It contains a statolith, a dense mineral particle that responds to the movement of the animal's body and helps to stimulate sensory cells called mechanoreceptors. The other choices (neuromast, ommatidium, and olfactory bulb) do not match the structure shown in the figure.
