Lung cancer cells do not respond to the signals that regulate the growth of normal lung cells. Which of the following processes is NOT appropriately regulated in the cancerous cells?

The correct answer is : mitosis.

Explanation:

Malignant growth or cancer is basically an abnormality of mitosis - the ordinary 'checkpoints' directing mitosis are ignored by the tumor cell. Disease starts when a single cell is altered, or changed over from an ordinary cell to a malignant growth cell.  

Mitosis is firmly constrained by the qualities inside each cell. If genes did not control or perform their work properly  occurs in only a single cell, it can reproduce itself to make new cells that are likewise uncontrollable and leads to tumor or cancer.

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
