Replication of RNA genome in RNA virus does not involve proofreading. Thus RNA viruses have higher rates of mutation. So the correct option is B.

<h3>What is meant by proofreading? </h3><h3> </h3>

There are a variety of mechanisms in the cell to prevent mutations. Thus, permanent changes in the DNA sequence are prevented.

During the process of synthesis of DNA, DNA polymerases can analyse any mistake made during the synthesis and fix it. The majority of mispaired bases can be fixed by this process. It is called proofreading.

This process is not present in RNA and RNA polymerases. Thus RNA viruses appear to have higher rates of mutation compared to DNA viruses.

Therefore the correct option is B.

With the advent of industrialization, several trees have been cut at an alarming rate for raw materials and various other purposes. This felling of trees can be regulated by selective cutting, clear-cutting and shelterwood cutting.

Forest fires are one of the common causes of loss of forests. Sometimes the forest land is set on fire to make the land available for commercial purposes. Once cleared, there can be no vegetation. Natural forest fires are also responsible for the destruction of huge forest covers. Latest fire fighting techniques should be adopted to conserve the forest. However, forest fires are an important part of the ecosystem and it helps replenish nutrients in the soil from dead and decaying matter.

More trees should be planted to increase the forest cover. Trees should be selected according to the geographical conditions of a particular region and proper care should be taken during the growth of trees.

Prevention of exploitation of forestry and forest products is necessary for the conservation of forest.

The existing forests should be protected from diseases by spraying chemicals, antibiotics or development of pest-resistant strains of trees.
