Question
can someone help me label these correctly?
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. omine shaft Key Copper-contaminated soil Uncontaminated soil Sites where nearly 10ok of the monkey-flower plants are copper tolerant at 0.5 pg/cm O Sites where less than 20% of the monkey-flower plants are copper tolerant lake O Pearson Education, Inc. Use the map to determine which of the statements below are true. Select the three statements that are true. » View Available Hint(s) O Natural selection favors copper tolerance in all soils near the old mine, not only in the contaminated soils. O Copper-tolerant plants are found only in contaminated soils. O The population that existed before mining must have included both copper-tolerant and copper-intolerant plants. O Nearly 100% of monkey flowers growing in copper-contaminated soil are copper tolerant. O 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. O Copper contamination in the soil created copper-tolerant plants.Explanation / Answer
Over the evolution, natural selection has helped the monkey flowers to grow. The natural selection has developed copper tolerance in the monkey flowers. In case, these were not copper tolerant then they would not have been able to survive. Due to the copper tolerant trait, the monkeyflowers are able to survive in copper-rich soils and also in soil that is not rich in copper. Therefore, the first statement is correct.
All the plants growing in the copper-contaminated soil has the copper tolerant trait and the soil is rich in copper content and therefore they are able to survive in the copper-rich soil. Hence, the fourth statement is true.
In case, the monkey flowers were made to grow near the lake soil then they will 100% copper tolerant plant. This is because the copper tolerant trait is present in all the monkey flower plants and the soil present near the lake consists of copper-rich soil. Therefore, the fifth statement is correct.
The copper tolerance is a trait in the monkey flowers that makes the plant survive even in the soil having a high content of copper. However, this trait does not hamper the normal growth of the plant in the soil having less copper content. It can be seen in the figure given that sites where 20% and fewer monkey plants were present and they were copper tolerant. Therefore, the second statement is wrong.
The population of the monkey flowers will have copper tolerant and this trait has been developed over the period of time. Therefore, the copper tolerance is not developed after the mining. This trait is present in all the monkey plants. No monkey plant was copper intolerant. Therefore, the third statement is false.
Copper contamination did not lead to copper tolerant plants. These plants have copper tolerance trait that has been inherited during the evolution. Therefore, the sixth statement is incorrect.
