Question
1 Sensory neurons respond to an appropriate sensory stimulus with a change in membrane potential that is all or nothing.
• graded with the stimulus intensity. always small and subthreshold. always large and suprathreshold.
• graded with the stimulus intensity. always small and subthreshold. always large and suprathreshold.

Sensory neurons respond to an appropriate sensory stimulus with a graded change in membrane potential. This means that the change in potential is proportional to the strength of the stimulus, rather than being an all-or-nothing response.
So the correct statement should be:
- **Graded with the stimulus intensity.**
This implies that stronger stimuli will produce larger receptor potentials in sensory neurons, which can lead to action potentials if the graded potential reaches the threshold.
