A) Your body possesses no energy after you die because it cannot move on its own.
B) Your body possesses both potential and kinetic energy even as it lies still.
C) Your body possesses chemical potential energy, which is the potential energy found within the atoms and molecules of your tissues.

Question 2
A person may feel more relaxed after smoking a cigarette, but his or her heart is actually stressed. Why?
A) Maintenance neurons are being activated by the nicotine, which directs maintenance neurotransmitters to instead activate stress neurons.

C) Stress neurons are over-firing to make up for nicotine's inhibition of acetylcholine.
D) The relaxed feeling arises only after the stimulated muscles rebound from a point of fatigue generated by the inhibition of acetylcholine.
