Dual innervation refers to an organ receiving a) both sensory and motor nerves. b) both sympathetic and parasympathetic innervation. c) two nerves from the spinal cord. d) nerves from both the brain and the spinal cord. e) both autonomic and somatomotor nerves

The correct option is B.

Explanation:

Dual innervation is a biochemical process by which an organ receives two different types of stimulation simultaneously. The principal function of dual innervation is to maintain the homeostatic balance of the body system. Dual innervation is brought about by two different systems, the sympathetic and the parasympathetic nerve systems. Although the actions of these two nerve systems are opposites to one another, they work together to bring balance to the body system. Without dual innervation the homeostatic system of the body can not be maintained.  

b - the respond is innate and varies over time.

good luck!
