Newborns have a small surface area to body mass ratio
Newborns have limited use of voluntary muscle activity or movement to produce heat.
Newborns have limited stores of metabolic substrates (glucose, glycogen, fat).
Newborns have a large surface area to body mass ratio.
Correct Answer : A,C,D,E
A. Newborns cannot shiver effectively to produce heat until around 3 months of age, making them more vulnerable to cold stress.
B. Newborns do not have a small surface area to body mass ratio; instead, they have a large ratio, which increases heat loss.
C. Limited voluntary muscle activity reduces their ability to generate heat through movement.
D. Newborns have only limited metabolic reserves (glycogen, glucose, fat), making it harder for them to sustain thermogenesis.
E. A large surface area relative to body mass increases susceptibility to heat loss through radiation, conduction, convection, and evaporation.
