Answer:
D. First law of thermodynamics
Explanation:
The first law of thermodynamics refers that energy can be tranferred or changed form one form to another but it can neither be destroyed nor be created. hence, it is also known as law of conservation of energy.
The equation ΔU = Q − W describes the first law of thermodynamics.
Where
- U is the internl energy of the system.
- ΔU is the change in U.
- Q refers to the total heat supplied into the system (include both addition and release of energy in the system).
- W is the net work done by the system.
Hence, the correct option is D.

The postganglionic axons typically terminate in several visceral effectors and therefore the effects of sympathetic stimulation are more widespread than the effects of parasympathetic stimulation.
