Which physiological risk increases when a hibernating mammal experiences frequent arousal during its hibernation period?

💡 Explanation

When a hibernating mammal experiences frequent arousals, it engages in thermogenesis causing rapid metabolic increase and excessive usage of brown fat reserves due to increased mitochondrial uncoupling. Therefore, brown fat depletion results, rather than edema, arrhythmia, or atrophy requiring different long term physilogical changes.

• Which effect arises when small mammals near their lower critical temperature?
• Which function does rapid luciferin depletion serve during anglerfish predation?
• Which limitation arises when migratory birds rely solely on spatial memory navigation maps?
• Which navigational error occurs when polarized light availability changes, impairing the location 'maps' used by migrating monarch butterflies?
• Which advantage arises when birds use slotted feathers under turbulent conditions?
• Which mechanism impairs avian flight during periods of prolonged heavy rainfall, increasing effective stall speed?
