Based on the graphs, which statement about hibernation in the ground squirrel is true? Arousal from hibernation begins with a rapid rise in body temperature, followed by a slow rise in metabolic heat production. During the hibernation season, the squirrel maintains its body temperature at a temperature close to freezing. At the onset of hibernation, metabolic rate rises as body temperature drops. During the hibernation season, the squirrel spends about as much time at a normal body temperature as it does at a body temperature close to 0°C. During hibernation the squirrel maintains a constant metabolic rate that is close to its basal metabolic rate.
