How do cells respond if a complex organism is injured?
Cells work to repair the injured area through meiosis.
Nearby cells change into stem cells in order to repair the injury.
Cells rush to the damaged area, proliferate through mitosis, and work to repair the injury.
• Cells form a blastocyst that contributes to the healing of the injury.

Correct answer: "Cells rush to the damaged area, proliferate through mitosis, and work to repair the injury."

Why: Repair in complex organisms involves migration of immune and repair cells to the site, activation of local stem/progenitor cells, and cell division by mitosis to replace lost cells and rebuild tissue. Meiosis and blastocyst formation are unrelated to wound healing, and differentiated cells generally do not convert into stem cells in typical mammalian repair.
