Answer:
Parasympathetic nervous system
Explanation:
The parasympathetic nervous system of the autonomic nervous system is activated to restore the body's energy level after the emergency conditions. This division of the autonomic nervous system triggers the digestion and absorption of nutrients so that body cells obtain and conserve energy.
Some of the responses generated by activated parasympathetic division are increased activity of glands associated with the digestive system and increased the contraction of smooth muscles of the digestive tract. The parasympathetic nervous system also slows down the responses required for physical activities such as heart rate and breathing rate.

would have the same genes. For example, one could have green eyes and the other
could have brown eyes.
