We're doing a project in school where we will test Bisphenol A on organisms and see how they affect their reproductive ability, but we do not know which animal we should test on. They must reproduce quickly and it must have a reproduction similar to that of humans, so it cannot be bacteria. It must not be vertebrate or fish because then we must seek permission to test on them. Does anyone have a suggestion on what organism we can test it on?
