Answer: The correct answer is D.
Shivering is a bodily function that prevents the loss of heat. It is found in warm-blooded animals and mammals.
When the body temperature drops, the skeletal muscles begin to shiver in small movements ( shaking ), creating warmth by expanding energy. It is done to maintain homeostasis ( the steady internal and chemical condition of the body).
Newborn babies, infants and small children experience greater heat loss because their bodies do not know how to shiver yet. This is why is it always recommended to wrap them up warmly and make them drink warm liquids. Some elderly may experience problems with limited heat loss as well.
The final answer is (D) In order to conserve body heat, the body will begin (D) shivering.
Hope this helps... Stay safe and have a great day/night!!!! :D
