Malignant tumor:
Correct answer: B. Rapid division
- A. Diplotene
- B. Rapid division
- C. Cell cleavage
- D. Missing X
Explanation
In malignant tumors, the process of cell division becomes dysregulated due to mutations in genes that control cell cycle checkpoints and cell growth. This dysregulation leads to uncontrolled and rapid cell division, resulting in the formation of abnormal cell masses. These cancerous cells can proliferate without regard for the body's normal mechanisms that regulate cell division, leading to the growth of tumors that invade surrounding tissues and can spread to other parts of the body, a process known as metastasis.
