D. Action potential B, phase 0 = PQ interval
E. Action potential A, phase 4 = ST segment
### Graph Explanation for Educational Website The image consists of two graphs labeled A and B. Each graph represents different phases of a process, numbered from 0 to 4. #### Graph A: 1. **Phase 0 to 1**: A sharp increase in the curve, indicating a rapid progression or initiation of an event. 2. **Phase 1 to 2**: A small dip followed by a stabilization at a higher level. This suggests a momentary setback or adjustment. 3. **Phase 2 to 3**: The curve gradually declines downward, suggesting a decrease in the process activity. 4. **Phase 3 to 4**: A further decline, leading to a steady, low state. This indicates the conclusion or stabilization of the process at a minimal level. A dotted horizontal line runs parallel to the x-axis, intersecting the graph between phases 2 and 3. #### Graph B: 1. **Phase 0**: Initial position starts below the dotted line. 2. **Phase 0 to 3**: The curve rises above the dotted line, indicating a peak or climax in the activity. 3. **Phase 3 to 4**: A decline, bringing the curve back below the dotted line, suggesting a reduction or end of the process. A dotted horizontal line also runs parallel to the x-axis, providing a reference point above which part of the graph extends and below which it stabilizes at different phases. These graphs can be used to illustrate processes such as reaction phases, economic cycles, or biological activities, depending on the context of study.
