What is the benefit to using tissue cultures with cancer patients? doctors can study how quickly cancer spreads in the culture so they know what medicine to use. medications can be tested on the cancer culture before being injected into the patient. the cancer culture can be studied to determine if oral medicine is the best treatment for the patient.

Correct B). Medications can be tested on the cancer culture before being injected into the patient.

Medications have the dangerous side effects on the body and it may or may not be effective in killing or inhibiting the growth of a cancerous cell. That is why now a days tissue culture technique is used to test the potential drug before administrating it to the patient.

Growing cancer cell in the laboratory is a good way to learn about cancer and to determine the effective medicine against a particular type of cancer.  

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
