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 A, because these minerals will act as toxins to the plant as they are absorbed through the roots. B) 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. 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.
