Answer

Answer:

A. Patients do not receive harmful or ineffective medication.

Brief Explanations:

Using tissue cultures to study medicines allows scientists to test the efficacy and safety of potential drugs before using them on patients. This way, only medications that show promise in the tissue - culture tests (i.e., are effective and not harmful) are likely to be administered to patients. Option B is a drawback of tissue cultures (cells not in normal environment may not behave exactly as in the body). Option C is incorrect as doctors do not know how to treat all types of cancer. Option D is wrong because different cancer patients may have different cancer cell characteristics, so one tissue culture cannot be used for all.
