Question

Quizplus · Accepted Answer

The statoliths in a lobster's body are responsible for its sense of balance and orientation. By replacing them with iron filings, the lobster's sense of balance would be severely disrupted. When a strong magnetic field is produced above the tank, the iron filings would align themselves with the magnetic field, causing the lobster to be affected by the magnetic force. This would cause the lobster to tend to remain upside down gripping the underside of the top of the tank. Thus, choice B is the most likely response.
