Answer:

1-A,   2-C,   3- D

Explanation:

Took the test and got it right!

Cells are the unit of life that makes the whole organism. The normal cells, compared to cancerous cells do not move from one organ or system to another. Thus, the correct options are 1. D, 2. B, and 3. A.

What are cancerous cells?

Cancerous cells have lost their ability to stop cell differentiation and division, leading to uncontrollable growth, unlike the normal cells that are fixed at their location and do not move. Hence, option D is correct.

Cancer can be benign or malignant. A benign tumor is less harmful than a cancerous tumor as they are fixed in one place and does not invade other organs and systems. Hence, option B is correct.

Cancers can be caused due to many environmental factors like certain drugs or chemicals, a mutation in the BRCA1 gene, and UV radiation. But, human papillomavirus (HPV) is not an environmental factor that causes cancer. Hence, option A is correct.

Therefore, the normal cells stay at a fixed position.
