Franklin is listening to music with the volume fairly low; Cecilia is listening to music with the volume turned to
the maximum.

a. the action potentials in both individuals will be the same due to the all-or-none principle.
b. the action potentials in Cecilia’s nervous system will travel more quickly because the incoming signal is
more intense.
c. the action potentials in Franklin’s nervous system will be weaker because the incoming signal is less
intense.
d. the action potentials in Franklin’s nervous system will travel a shorter distance because the incoming
signal is less intense.

a. the action potentials in both individuals will be the same due to the all-or-none principle.

Explanation:

Franklin is listening to music with the volume fairly low; Cecilia is listening to music with the volume turned to  the maximum.

Based on what is known about action potentials, you could predict that for these two individuals, the action potentials action potentials in both individuals will be the same due to the all-or-none principle.

a. the action potentials in both individuals will be the same due to the all-or-none principle.

Explanation:

The all or none principle states that the power in which a nerve responds to a stimulus is independent of the power of the stimulus.

Stimulus causes cells of the body to respond to them. In this case the music is the stimulus. The way nerve of cells responds to the stimuli isn’t dependent on the power. This means as long as the stimulus is felt everyone’s cells would respond to it in the same way irregardless of the strength of the stimulus.
