![### Transcription and Explanation
This image contains a graph illustrating the phases of action potential typically found in cardiac cells. The graph plots membrane potential (in millivolts, mV) on the vertical axis against time (in seconds) on the horizontal axis.
#### Graph Details:
1. **Axis:**
- **Vertical Axis (Y-axis):** Represents membrane potential, ranging from -80 mV to +20 mV.
- **Horizontal Axis (X-axis):** Represents time, showing intervals where different phases occur.
2. **Graph Lines and Phases:**
- **Line 'a':** Represents the depolarization phase, where the membrane potential rises steeply from around -60 mV to above 0 mV, peaking at about +20 mV.
- **Line 'b':** Represents the repolarization phase, where the potential returns from its peak back toward the resting potential.
- **Lines 'c' and 'd':** Likely representing the pacemaker potential, where the membrane potential slowly increases from around -60 mV toward the threshold for the next depolarization.
#### Interactive Elements:
- Below the graph, there are dropdown menus labeled:
- `a [Choose]`
- `b [Choose]`
- `c and d [Choose]`
Each dropdown allows the user to select from different options to match the phases of action potential. The options provided in the menu are:
- Depolarization phase
- Repolarization phase
- Pacemaker potential
This interactive feature is designed to test the user's ability to correctly identify and match the phases of action potential based on the graph.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F950ccb0b-88f0-424e-a789-46ed3bd2a086%2F68308dea-7c55-4a7c-9d88-0438f6997d2b%2Fhb3wqn8_processed.jpeg&w=3840&q=75)
