Male amphibians, including frogs and toads, have been plagued by feminization, deformity, behavioral abnormalities, and sterility. Biologists from the University of Florida investigated whether reproductive problems among populations of cane toads (Bufo marinus) are caused by poisons from chemicals associated with agriculture. The biologists collected local adult cane toads from more than 20 different locations. Toads were collected from areas close to agriculture, both large-scale and small-scale farms, as well as from suburbs that are nonagricultural areas. Data collected by the biologists suggested a strong correlation between feminization of male toads and agricultural chemicals. Is it accurate to state that the scientists had supported their theory that agricultural chemicals cause deformities?

No, the scientists were testing a hypothesis which is not the same things as a theory.

Which answer choice lists the steps of the scientific method in the correct order?
