Answer:
a.They evade the normal controls that trigger programmed cell death.
Explanation:
Cancer cells are cells in the body that grow abnormal and uncontrollably. Continuous growth cancer cells results in the development of tumor as well as the ability to invade neighboring tissues.
Unlike normal cells that are controlled (reproduce only when needed) and are more specialized with specific functions, cancer cells are less specialized compared to normal cells and grow abnormally and rapidly. Cancers cells grow out of control, as they evade the normal control and ignore signals that activate apoptosis or programmed cell death which is used by the body system to destroy unwanted cells.
At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes.
