Which statement about cancer is true?
A. Mutations in certain genes cause tumors
B. Growth factors control when and how fast cells die
C. Cancer starts when cells stop growing and dividing
I think it’s C but idk
Horrible question. A and B are both true. But I would say that A. Is the answer choice that the author of the question is looking for.
The correct statement among the options provided is A. Mutations in certain genes cause tumors.
To understand why, let's analyze each statement:
A. Mutations in certain genes cause tumors: This statement is true. Cancer is often caused by genetic mutations that disrupt normal cell growth and division. When specific genes, known as oncogenes or tumor suppressor genes, acquire mutations, they can lead to the uncontrolled growth and division of cells, forming tumors.
B. Growth factors control when and how fast cells die: This statement is not correct. Growth factors are signaling molecules that promote cell growth and division, but they do not directly control when and how fast cells die. The process of cell death, also known as apoptosis, is regulated by different cellular mechanisms.
C. Cancer starts when cells stop growing and dividing: This statement is not true. On the contrary, cancer is characterized by uncontrolled and abnormal cell growth and division. When cells stop responding to signals that normally regulate their growth and division, they can develop into cancer cells.
Thus, the correct statement is A. Mutations in certain genes cause tumors, as gene mutations are often the underlying cause of cancer.
