Cell replication is meant to be a very regulated process. Messages are sent to the cell, telling it when to duplicate and when not to. When cells divide according to their natural plan, then there are no problems. However, when cells either do not receive those messages or misinterpret them, they can divide too fast and without pause. These renegade cells are what we call cancer cells.
Answer:
Explanation: When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective. ... this is actually why cells divide.
Explanation:
D because they are complete systems
