Fiona puts her hands into a sinkful of lukewarm water; Luke puts his hands into a sinkful of ice-cold water. Based on what is known about neural transmission, you could predict that the action potentials will

A) travel more quickly in Luke's system because the stimulus is more intense.
B) be weaker in Fiona's system because the stimulus is less intense.
C) be the same in both individuals due to the all-or-none principle.
D) travel a shorter distance in Luke's system because the stimulus is more intense.

Question

Christopher Klemowski · Accepted Answer

Final Answer : C, Explanation :  The all-or-none principle of neural transmission states that a neuron either fires an action potential or it doesn't. The intensity of the stimulus does not affect the speed or strength of the action potential, so it would be the same in both individuals regardless of the temperature of the water they put their hands in.
