← Nature & AnimalsWhich consequence results when vasodilation is suppressed during hibernation?
A)Increased metabolic rate generation
B)Localized tissue ice crystal formation✓
C)Brown fat cell hyperthermia induction
D)Enhanced core body temperature control
💡 Explanation
Suppressed vasodilation prevents blood from delivering heat to extremities; the tissue cooling from the environment causes localized freezing, triggering ice crystal formation, because blood flow cannot maintain tissue temperatures. Therefore, ice forms, rather than maintaining heat because vasoconstriction promotes heat conservation.
