How are tumor cells different from normal cells a: mitosis is not regulated in tumor cells b: tumor cells use meiosis to replicate c: tumor cells are haploid and other cells are diploid d: there are no chromosome in tumor cells

Tumor cells differ from normal cells in that A) Mitosis is not regulated in tumor cells.

This is seen when tumors grow to large amounts rather quickly. Mitosis is not regulated, and therefore the cells continue to multiply and that is when we are able to see and feel a palpable cancer mass - their growth is uncontrolled.
