Answer:
The Ozone Layer would repair
Explanation:
CFC's are chlorofluorocarbons. They generally eat the ozone layer. It stands to reason that a reduction in CFC's would reduce the depletion of the ozone layer allowing it to slowly repair itself through natural processes.
The answer is B, because cells make up tissue, tissue makes up organs, organs make up the organ system, and an organ system makes up an organism. Imagine it as a process from least to greatest complexity.
The stem cells divide through mitosis making two daughter cells. One daughter cell becomes a stem wall, and the other daughter cell differentiates into the tissue, so therefore stem cells maintain their populations because mitosis produces a daughter cell that differentiates, as well as one that self-renews, remaining a stem cell. Good luck, and hopefully this helps you out!
