Which outcome results when a hibernating groundhog's muscle glycogen stores are depleted as environmental temperatures suddenly drop?

💡 Explanation

Groundhogs initiate shivering thermogenesis because muscle glycogen depletion limits brown fat activity; shivering produces metabolic heat therefore shivering must drive glucose mobilization rather than brown fat catabolism.

• Which mechanism causes a groundhog's body temperature to increase as it exits hibernation?
• Which navigational failure results when starling flocks encounter magnetic anomalies?
• Which selective pressure favors bioluminescence in deep-sea anglerfish?
• Which obstacle delays metamorphosis among hemimetabolous insect nymphs?
• Which metabolic outcome prevents awakening during early stages of mammalian hibernation?
• Which thermal outcome follows disruption of dormancy control during hibernation?
