Quizplus · Accepted Answer

The Ob/ob mice have a mutation that decreases their production of leptin, a hormone that regulates appetite and metabolism. As a result, these mice have a reduced metabolic rate and are more efficient at converting calories to fat. Therefore, both A and B are correct statements. However, since Ob/ob mice have low leptin levels due to the mutation, option C is incorrect.
