If any single test of a scientific hypothesis contradicts it, the hypothesis must be revised. (Assume that you've ruled out errors in the testing process; that is, the test result really does contradict the hypothesis.)

The correct answer is : True

Explanation:

When a hypothesis hasn't been confirmed after several different experiments, and the reproducible ones show the hypothesis does not work, it is possible to reject it and to replace it with a new one. Correcting any mathematical calculations is a necessary step after any experiment.

neurotics: attack nerve cells

mutagens: damage or otherwise alter dna sequence

generators: cause defects during growth and development  

carcinogens: cause unchecked cell growth

i hope you get the idea according to me these are the effects that happened.
