Question

question 5 (mandatory) (2 points)
malignant cells ,______.
a) grow and divide by mitosis normally
b) grow and divide by mitosis abnormally
c) are found in tissues that are not overcrowded with cells
d) reproduce very slowly
e) have very few blood vessels

Explanation:

Malignant cells are cancerous cells. They do not follow normal cell - growth regulations. Normal cells grow and divide in an orderly fashion (by mitosis) when needed, but malignant cells grow and divide abnormally (uncontrolled mitosis). Also, malignant tumors (made of malignant cells) can be overcrowded with cells as they keep dividing. They reproduce rapidly (not slowly) and often stimulate angiogenesis (formation of new blood vessels) to supply their growth needs.

Answer:

B. grow and divide by mitosis abnormally
