The highly regulated process of apoptosis is not simply the destruction of acell; it is also an emergent property. Write a short essay (about100–150 words) that briefly explains the role of apoptosis inthe development and proper functioning of an animal, and describe how this form of programmed cell death is a process thatemerges from the orderly integration of signaling pathways.
