A person damages some muscle tissue. Unspecialised cells produce new cells to replace the damaged muscle cells.
Which statement explains why differentiation is needed during the repair?
It gives replacement cells structures adapted for contraction.
It keeps replacement cells unspecialised so they can perform several jobs.
It makes damaged muscle cells contract more strongly during repair.
It removes most sub-cellular structures so replacement cells can contract.
