In Adult Animals,cells Move Through the Cell Cycle with Varying

In adult animals,cells move through the cell cycle with varying levels of speed.Cells that have differentiated and taken on specific roles may not divide whereas those that are exposed to harsh conditions,such as a low pH,may turnover regularly.On the other hand animals that are rapidly growing must generate cells rapidly.Which choice represents the correct pairing based on cell type and speed through the cell cycle?

A) Adult bone cells move slowly through the cell cycle compared to embryonic bone cells.
B) Adult gastro-intestinal tract cells move slowly through the cell cycle compared to adult nervous system cells.
C) Adult nervous system cells move rapidly through the cell cycle compared to embryonic nervous system cells.
D) Adult bone cells move rapidly through the cell cycle compared to embryonic bone cells.
