Explanation:
In mammals, the contraction of the heart muscle is caused by pacemaker cells localized within the sinoatrial (SA) node. These cells rhythmically generate slow electrically-induced action potentials due to their slow rate of depolarization. The pacemaker cells generate the action potentials that propagate through the heart and trigger the contraction of myocyte cells (i.e., myocytes simply conduct the action potential waves). The slow depolarization of pacemaker cells occurs during diastole, i.e., during the period of relaxation of the heart muscle.
<span>When running, one conflict that might arise is how far you are able to run without stopping for water. You might want to go a very long way and be unfamiliar with the area, so it is important to have scouted ahead for any place that can offer a drink.

Answer:
If mitosis skipped any of the stages, it would result in a mutated cell. If the cell skipped Metaphase, it could make daughter cells that are different than the parent cells. If the cell skipped Telophase, the cell would not divide, and the parent cell would attempt interphase with another nucleus.
Explanation:
The cell cycle has two main phases, interphase and mitosis. Mitosis is the process during which one cell divides into two. Interphase is the time during which preparations for mitosis are made.
