Some monkey flowers (Mimulus guttatus) living near the sites of copper mines can grow in soil containing high concentrations of copper, which is toxic to most plants. Copper tolerance is a heritable trait.
The map below shows the area near an old copper mine, which contaminated the nearby soil with copper. A stream flows past the mine toward the lake at the bottom right of the map. Use the map to determine which of the statements below are true.Select thethreestatements that are true.Select thethreestatements that are true.The population that existed before mining must have included both copper-tolerant and copper-intolerant plants.Nearly 100% of monkey flowers growing in copper-contaminated soil are copper tolerant.Natural selection favors copper tolerance inallsoils near the old mine, not only in the contaminated soils.Copper contamination in the soil created copper-tolerant plants.Copper-tolerant plants are foundonlyin contaminated soils.If you were to test monkey flowers growing on the shore of the lake, you would expect nearly 100% of them to be copper tolerant.

3 true statements are- Nearly 100% of monkey flowers growing in copper-contaminated soil are copper tolerant. The population that existed before mining must have included both copper-tolerant and copper-intolerant plants. If you were to test monkey flowers growing on the shore of the lake, you would expect nearly 100% of them to be copper tolerant.

High concentrations of copper are toxic to plants that cannot survive in soils containing too much copper as the question state. However, many monkey flowers have evolved and they have resistance to this toxicity, also managing to survive in soils with high copper concentration. It is because, earlier the monkey flower population had already copper-resistant and non-copper-resistant plants. Later by natural selection, the copper-resistant plants survived and non-copper-resistant plants eventually died. This is the characteristic of that plant descendants, that is by it is forming a population of almost 100% of copper resistant plants.

Therefore, nearly 100% of monkey flowers growing are copper tolerant. The population have both copper-tolerant and copper-intolerant plants. If you were to test monkey flowers growing on the shore of the lake, you would expect nearly 100% of them to be copper tolerant.
