What is the spreading of tumor cells to distant parts of the body via blood and lymph referred to as? A) Mitosis. B) Metastasis.
Alisiya [41]
<span>The correct answer is 'metastasis'. This is the migration of cancer cells from one place to another in the body. They do this by travelling through the blood stream or the lymphatic system. Mitosis is the process of asexual cell division. It produces cells that are identical to the original cell as one cell divides into two after replicating its organelles and genetic information. (Mitosis makes my toes.) Apoptosis is controlled cell death. When cells are getting old then they need to be replaced. Old cells are programmed to 'die' at the correct time. The cell contents are recycled to make new cells.</span>
