Several Chemical Pollutants from a Paper Mill Are Released into the Nearby

question 44

Multiple Choice

Several chemical pollutants from a paper mill are released into the nearby environment. Compound A is rich in calcium and magnesium. Compound B binds tightly to all free polypeptides and proteins in the soil. Compound C is structurally similar to abscisic acid. Based on this scenario, which compound will most likely harm the surrounding vegetation, and what effect(s) will it have on the plants?

• A) Compound C, because abscisic acid inhibits the active transport of potassium ions and thus closes the stomata, which will interfere with CO₂ uptake and H₂O transport.
• B) Compound A, because these minerals will act as toxins to the plant as they are absorbed through the roots.
• C) Compound B, because it ties up free polypeptides and proteins in the soil, preventing their uptake by plants, which is critical for plant growth.
