Refer to the Table

Short Answer

Refer to the table.In mice, a single-gene mutation can lead to obesity.The Ob gene codes for the protein leptin.The recessive ob allele is a loss-of-function allele, so ob/ob mice do not produce leptin.In an experiment, leptin was injected into ob/ob and Ob/Ob (wild-type) mice daily.The data in the table below were collected before the injections began (baseline) and 10 days later.(Assume that the Ob allele is dominant.) Suppose that on day 11 of the study, the leptin injections are halted and measurements on the mice are taken again at day 20.What values for food intake, body mass, metabolic rate, and body temperature might one reasonably expect to observe at day 20?
