Question

What is the stress faced by naked mole rats in their crowded burrows?
A) less carbon dioxide in their blood
B) elevated tissue acidity
C) dehydration
D) food shortages
E) insufficient rest

Accepted Answer

Naked mole rats live in crowded burrows where oxygen levels are low and carbon dioxide levels are high. As a result, they have evolved to tolerate this stressful environment by having a unique metabolism that produces energy using fructose instead of glucose. However, this metabolism results in elevated tissue acidity, which is a stressor for the naked mole rats.
