The somatic nervous system does not rely on the autonomic nervous system for involuntary events.
The body system that does not rely on the autonomic nervous system to stimulate involuntary events is the somatic nervous system.
The somatic nervous system controls voluntary actions such as movement of skeletal muscles, while the autonomic nervous system controls involuntary actions such as heartbeat and digestion.
Two examples of systems that are controlled by the autonomic nervous system are the cardiovascular system, which regulates heart rate and blood pressure, and the respiratory system, which controls breathing rate and depth.

Answer:
Option (1).
Explanation:
DNA (deoxyribo nucleic acid ) is the genetic material present in all the organisms except some viruses. DNA structure follows the Chargaff's rule.
Accoprding to Chargaff's rule, the ratio of purines to pyrimidines in a DNA molecule is equal to 1. The amount of guanine is nearly equal to the amount of cytosine whereas the amount of thymine is nearly equal to the amount of adenine.
Thus, the correct answer is option (1).
