Question
Paraquat is an herbicide that is effective against a wide range of grasses and broad-leaved plants. It is also toxic to animals and can only be used by licensed applicators. In 1975, Mexico, the largest supplier of marijuana to the United States at the time, tried to eliminate marijuana crops by spraying plants with paraquat. (Columbia then became the largest marijuana supplier). Paraquat is currently used in other applications, such as clearing fields, as it becomes inactive upon contact with soil.
Paraquat is an herbicide that is effective against a wide range of grasses and broad-leaved plants. It is also toxic to animals and can only be used by licensed applicators. In 1975, Mexico, the largest supplier of marijuana to the United States at the time, tried to eliminate marijuana crops by spraying plants with paraquat. (Columbia then became the largest marijuana supplier). Paraquat is currently used in other applications, such as clearing fields, as it becomes inactive upon contact with soil. Paraquat acts by accepting electrons that would otherwise reduce ferredoxin, and it can accept them from NADPH. The reduced form of paraquat then reacts with oxygen to form reactive oxygen species (in this case, O2), which damage chloroplast lipids and cause plant death. Which of the following can you infer from this information?Explanation / Answer
the answer is four and five.
