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.
N an experiment the "control" is the group of people or object this is used to measure the effect of the variable. The "control" is the thing that does not change and is not the thing in question.
In an experiment the "variable" is the thing which is changed and manipulated by the experimenter. It is the effect of something,
Example: You want to test a drug. you get a group of 40 people. 20 people are given the pill, 20 people are not given the pill but a sugar pill. the people who have the pill is the "variable" and the people who dont have the pill is the "control".
