A SCIENTIST NOTED A POSSIBLE RELATIONSHIP BETWEEN A CERTAIN CHEMICAL SUBSTANCE FOUND IN FISH AND THE OCCURRENCE OF THE KIDNEY FAILURE IN HUMANS. WHICH STEPS SHOULD THE SCIENTIST BEFORE CONDUCTING EXPERIMENT.

Answer 1

First, please do not use all capitals. Online it is like SHOUTING. Not only is it rude, but it is harder to understand. Thank you.

I don't think the experiment should be conducted, because administering the chemical to the experimental group could cause kidney failure.

Even so, if differences in voluntary consumption are evident, the incidence if kidney failure could be noted. However, this would probably a longitudinal study that would take decades.
