If the cell cycle is carefully controlled by proteins that are present only temporarily to help turn on the cell cycle (i. e. growth factors) and other proteins that halt the cycle (checkpoint proteins), what do you suppose would happen if a cell was continuously exposed to growth factors?

How do water’s relative densities as a solid and a liquid differ from that of most other substances? water’s solid and liquid forms have different densities, while most other substances have solid and liquid forms with similar densities. water’s solid and liquid forms have similar densities, while most other substances have solid and liquid forms with different densities. water’s liquid form is less dense than its solid form, while the opposite is true of most other substances. water’s solid form is less dense than its liquid form, while the opposite is true of most other substances.
