Plants do not grow near the old copper mine because of the excess copper deposited in them impairs cellular processes and inhibits plant growth.
What are micronutrients?
These are required by plants in much smaller quantities less than 1% of the dry weight but are necessary for growth and development. There are 7 essential plant nutrients like boron (B), zinc (Zn), manganese (Mn), iron (Fe), copper (Cu), molybdenum (Mo), and, chlorine (Cl).
Copper activates some enzymes in plants that are involved in lignin synthesis and are required in the process of photosynthesis.
Excess copper causes reduced seed germination, low shoot vigour, and lower iron availability. A deficiency of copper can lead to increased to susceptibility to diseases like ergot, which can cause significant loss in the yield.
Plants growing in the old copper mine have the excess deposition of copper in one place which affects the germination of seeds hence it is found difficult to grow in the old copper mine.
Plants can grow easily in a place that is further away from the old copper mine. Because there is a high concentration of copper dissolved in water in the soil, this helps the plant to grow by exhibiting the photosynthesis process.

What is the question or paper? there isn’t really a question here if there is nothing to look at lol

Explanation:
Continental glaciers flow outward in all directions from a central point.
Answer:
Finches on the island with better-adapted beak sizes have increased survival.
Explanation:
Answer:
C) A stretch of DNA that does not code for anything, created by pasting together DNA from a mouse and DNA from a bacterium.
Explanation:
The DNA that is produced artificially by combining the DNA of different individuals or different organisms is known as recombinant DNA.
These recombinant DNA can be used for different purposes like for the production of recombinant products like recombinant hormone in the host organism, for example, production of human insulin in bacteria.
So if a segment mouse DNA and a segment of bacterial DNA are pasted together then it will be called recombinant DNA because the resultant DNA is made up by the recombination of DNA of two different organisms.
