C. The body failing to respond to signals that slow the cell cycle
-The body failing to respond to signals that slow the cell cycle: can result in irregularities leading to cancer.
Explanation;
-Cancer is caused by uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions are not favorable, therefore, too little activity of these inhibitors can promote cancer.
-Similarly, positive regulators of cell division can lead to cancer if they are too active. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.
