3. Which of the following statements about the activity of neurons is true?

a) A weak message can be used to stimulate a sensory neuron, but a strong message is needed to stimulate a motor neuron

b) A strong message received by a neuron will cause the neuron to generate a stronger action potential

c) A strong message will cause the release of neurotransmitters from the neuron, while a weak message will cause the release of hormones from the neuron

d) A strong message received by a neuron will cause the neuron to fire repeatedly, in a faster fashion
