Reаd the fоllоwing pаssаge and see the figure belоw. This is question 1 of 2 about this passage and figure. “The popular herbicide atrazine induces a compound that converts testosterone into estrogen. Researchers wanted to know whether the survival of some amphibian species could be at risk due to atrazine’s effects on the number, function, and fertility of males. In Hayes et al. (2002), researchers tested the hypothesis that atrazine reduces testosterone levels in male frogs by exposing one group of 90 male frogs to 25 parts per billion (ppb) atrazine every 3 days for 46 days. A group of 90 control males and a group of 90 control females were treated identically to the atrazine-treated group, except they were not exposed to atrazine. All frogs were housed individually and fed Purina rabbit chow. After 46 days, individual testosterone levels were measured in frogs from each group. The results are below.” QUESTION: What is a controlled variable in this experiment?
