← Nature & AnimalsWhich consequence results when a hibernating arctic ground squirrel's den is flooded at 0 °C?
A)Maintenance of constant core temperature
B)Increased shivering and metabolic suppression
C)Controlled vasoconstriction and energy conservation
D)Increased heart rate and arousals✓
💡 Explanation
Flooding causes rapid heat loss because conductive thermal transfer increases dramatically which overwhelms the adaptive hypothermia's ability to maintain low metabolic rates. Therefore, an increased heartrate and periodic arousal occurs rather than maintaining hypothermia, because the thermal gradient becomes too large for hibernation.
