Which outcome occurs when polar bear cubs lack sufficient brown fat during arctic storms?

💡 Explanation

Newborn cubs rely on thermogenesis from brown fat stores but insufficient amounts trigger shivering, generating metabolic heat because muscle contractions burn energy. Therefore shivering increases, rather than other metabolic changes, to compensate for low brown fat storage, despite energy cost.
