← Nature & AnimalsWhich consequence results when a hibernating marmot encounters interstitial fluid depletion?
A)Increased metabolic heat production occurs
B)Arteriole vasoconstriction is prematurely initiated✓
C)Osmotic regulation of cells fails steadily
D)Brown fat activity decreases drastically though
💡 Explanation
Premature arteriole vasoconstriction begins rapidly because peripheral interstitial fluid depletion reduces preload pressure and increases systemic resistance leading to vasoconstriction during torpor inducement, therefore interrupting hibernation rhythmicity, rather than metabolic changes or osmotic shifts.
