Well, here's what it is:
When wounds heal, cells are clumping together to form scabs.
When cells divide, they are breaking apart.
They both relate in a way, because both of them cause the cells to either multiply, or divide.
(Multiplying would be when it is divided, and dividing would be when it clumps together.)
I hope this helps, try creating your own paragraph using this idea. Note that plagiarism isn't the exact answer. (:
