Which effect occurs If a hibernating mammal's brown adipose tissue vascular resistance acutely increases?

💡 Explanation

When vascular resistance acutely increases, thermogenesis from brown adipose tissue declines because heat dissipation is reduced, leading to localized supercooling, inducing systemic hypothermia if oxygen supply becomes insufficient in other vital tissues. Therefore, irreversible hypothermia results, rather than incorrect metabolic rate, blood glucose, or arrhythmia, which require different cellular mechanisms.
