The autonomic nervous system is of two types: the sympathetic and the parasympathetic systems that is responsible for the mechanical and automatic functions in a human body.
<u>Explanation:</u>
The autonomic nervous system is of two types: the sympathetic and the parasympathetic systems that is responsible for the mechanical and automatic functions in a human body.
The parasympathetic nervous system is responsible for the digestion and relaxation of the body, it controls the homeostasis to keep the body in the right health, whereas the sympathetic nervous system helps in human body to react to things, to decide to whether to leave or fight the situation.

Expression can be influenced by factors that are not genetic.
<h3>What are non-genetic factors?</h3>
Factors that are not part of a person's genetic make-up are referred to as non-genetic factors. These elements include aspects of the surrounding environment as well as aspects of an organism's lifestyle that contribute to its makeup.
It has been demonstrated in a number of studies that the formation of some features is influenced by both hereditary and non-genetic variables.
In the situation described above, both of the monozygotic twins have diabetes, but the lifestyle choices made by one of them causes the condition to manifest itself seventy percent of the time. It's possible that the person is drinking more alcohol and eating more sugar.

The unit rate of the train in miles per hour is; 45 miles per hour
Distance traveled by train; d = 540 miles
Time of travel; t = 12 hours
Unit rate here will be the distance travelled per hour.
Formula for the unit rate here is;
Unit rate = distance travelled/time taken
Unit rate = 540/12
Unit rate = 45 miles per hour
