Question

Scientists use tissue cultures to study possible medicines that can be used to treat cancer patients. What is one benefit of this procedure?
Patients do not receive harmful or ineffective medication.
The cultured cells are not in their normal environment.
Doctors know how to treat all types of cancer.
One tissue culture can be used for all cancer patients.

Answer 1

Welll, in my experience, the correct answer should be A. Patients do not receive harmful or ineffective medication. All cancers are different so they can't all be treated the same way and one tissue does not represent the entire body. Cancer treatments are usually hard and aggressive so it's not a good thing to randomly test them on humans This is the reasoning behind this choice.
