Review the scenario. Cutthroat trout are a fish species native to cold-water rivers along the Pacific coast and the Rocky Mountains. While studying a population of cutthroat trout in one river, a scientist noticed that many male cutthroat trout had abnormal gonads, which are part of the male reproductive anatomy. The scientist wondered why the male fish had abnormal gonads. By reading other environmental studies carried out in the river, the scientist learned that the effluent, or released water, from a wastewater treatment plant upstream contained low concentrations of estrogen compounds. Estrogen is a hormone that can affect the development of reproductive traits in certain organisms. By reading other anatomical studies, the scientist learned that changes in hormones could affect the development of gonads in fish.
