In this question, there are no options given to choose from. I hope you wanted to know whether the statement in question is true or false. Based on this assumption, i am answering the question. It is true that London type smog typically forms when particles in coal smoke combine with water droplets in humid air.
In diseases, similar patterns of mutations in harmless genes may possibly be a cause or an effect of the disease. To investigate if it is a cause, it is worth looking into the proteins synthesized by the gene and whether it’s structure or functionality is affected by the pattern observed. It is also worth looking into the downstream effects possibly caused by the pattern in the gene. The gene may encode a non coding region which could affect post transcriptional splicing for example.
Answer:
B. Increased fertility of the land downstream
Explanation:
Dams are constructed across river to prevent water flow they conserve water for human use.
It has both advantages and disadvantages.
Dam are expensive to construct
Dam are used in generating hydropower, for supply of water for domestic use, irrigation,industrial use.
Dams detract from natural settings, ruin nature’s work
Dams leads to extinction of natural habitat, It could result in flood due to over flow, it leads to migration of people out of there homes due to it construction. Construction of dam is unlikely to increase fertility downstream.
An invasive species, such as the trees in your question, could:
- Out compete the native flora for resources, such as nutrients.
- An earlier reproductive and faster growing cycle could quickly surpass native tree growth.
- This alien species taking the place of native trees could disrupt the habitat of animal species that need the native flora instead.
