Answer
Cell division is important for adults to maintain tissue health; differentiation is the process whereby cells become specialized; apoptosis is programmed cell death; cell cycle regulators control the proper timing and fidelity of cell division.
Explanation
1. **Cell Division in Adults**: Even after an organism is fully developed, cell division remains crucial for the maintenance and repair of tissues. It helps replenish lost or damaged cells, ensuring the proper functioning of organs and systems.2. **Differentiation**: Differentiation is the process through which a cell changes from one cell type to another, typically from a less specialized type to a more specialized type. This is essential for the formation of different tissues and organs in an organism.3. **Apoptosis**: Apoptosis is the programmed cell death that serves to remove unnecessary or damaged cells in an organism. Its purpose is to maintain homeostasis and prevent the proliferation of potential sources of disease, such as cancerous cells.4. **Cell Cycle Regulators**: These are molecular signals that control the progression of cells through the cell cycle, ensuring that cell division occurs accurately and at the right time. They include proteins such as cyclins and cyclin-dependent kinases (CDKs).
