a.[3]
Describe the effect of attaching the drug to a monoclonal antibody on the mean tumour volume. Use data from the figure in your answer.
b.[2]
Explain why the drug attached to the monoclonal antibody was more effective than the drug given alone.
c.[2]
The scientists included a group of mice that were given no treatment. Explain why.
d.[1]
Give one reason why these results do not prove that the treatment will work in humans.
