The divergent boundary has shallow earthquakes, convergent boundary has little more intense earthquake and transform boundary has intense earthquakes.
Explanation:
The effect of divergent boundary is the occurrence of volcanic activities and shallow earthquakes. The structure of divergent boundary is like a dome shape. The effect of convergent boundary is the formation of mountain region and sea floor region. The structure of convergent boundary is like a sloppy surface in which one side is upper while the other side is lower. In this earthquake also occurs in these boundaries due to the presence of plate. The effect of transform boundary is the cause of intense earthquakes, the formation of thin valleys, and split river beds. The structure of transform boundary is like step of a ladder.
Tetanus is not possible in cardiac muscle tissue because cardiac cells have longer action potentials and a very long refractory period compared to other cells. This helps prevent the heart from cramping and seizing up.
