- (A) heat production
- (B) heat loss
- (C) sweating
- (D) permineralization
- (E) hypothermia
- (F) resistance
- (G) cramping
- (H) heat energy
The thinking starts now:
Shivering occurs when many muscles contract a little bit all at once. Heat production is increased by shivering and non-shivering thermogenesis . Heat production occurs when many muscles contract a little bit all at once. The final answer: (A).
