Final answer:
The step which is not part of tissue repair is the formation of new stem cells.
Step-by-step explanation:
The step which is not part of tissue repair is the formation of new stem cells. Tissue repair involves several steps, including inflammation, restoration, and regeneration. Inflammation is the initial response to injury, where the area becomes red, swollen, and painful. Restoration involves blood clotting and the formation of a scab, while regeneration occurs through the replacement of damaged cells with new ones from adult stem cells. However, the formation of new stem cells is not a step in tissue repair.
