Final answer:
Newborns have reflexes that help them survive, such as the Moro reflex, which is a response to the sensation of falling.
Step-by-step explanation:
The newborn's total body response to noise or movement represents a reflex that is expected in the healthy newborn. Newborns have various instinctive behaviors, or reflexes, that help them survive.
For example, the Moro reflex is the newborn's response to the sensation of falling, where the baby spreads its arms, pulls them back in, and may cry. These reflexes are present in babies whose brains are developing normally and usually disappear around 4-5 months old.
