Explain how the environment play a role in changing the frequency of a mutant allele in a poplution
tiny-mole [99]

Answer:

The environment plays a role in a mutant allele in a population because some mutations are more beneficial to the organism than other mutations.

Explanation:

Organisms with a beneficial allele mutation will be able to pass on their genes as they reproduce. The mutation makes them <em>fit</em> for survival in their environment. Other organisms <em>without </em>the beneficial allele won't be able to pass on their genes since it will be more difficult for them to survive in their environment. Natural selection will deem that the organisms with the mutation will survive better and be able to produce offspring with the same mutation.

In the area near an old copper mine,no plant grow. Go further away more and more plants are growing. An analysis of the soil nea

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.
