Question 2 • FL-2002040-M/J Comprehensive Science 1 CR

After the body has begun shivering, what explains why it would stop shivering?

Answer
A
When body temperature returns to normal, the respiratory system sends a message to the skeletal system to stop shaking.
B
When body temperature returns to normal, the nervous system sends a message to the muscular system to stop shaking.
C
While body temperature is below normal, the nervous system sends a message to the skeletal system to stop shaking.
D
While body temperature is below normal, the respiratory system sends a message to the muscular system to stop shaking.

Explanation

Shivering is caused by rapid, involuntary contractions of muscles when the body is too cold. Once body temperature returns to normal, the nervous system detects the change and signals the muscles to stop shivering. Therefore, choice B correctly identifies the nervous system and muscular system.
