QUESTION 1 Which of the followings about the Hypoxia in Gulf of Mexico is not true? Hypoxia refers to increased level of dissolved oxygen in water that is detrimental to aerobic organisms. Hypoxia in Gulf of Mexico is caused by dumping of nutrients from the Mississippi River basin. Ohio River basin contributed to the Hypoxia in the Gulf of Mexico. Level of nutrients in Mississippi River can be reduced in wetlands. When surface water is injected into an aquifer for...
