State a reason for the increased population of dark coloured moths coinciding with the loss of lichens (on tree barks) during industrialization period in England.

Explain the increases in the numbers of melanic(dark winged) moths in the urban areas of post-industrialisation period in England.

Apperance of dark-coloured peppered moths among the light-coloured ones as a result of increased industrial pollution is an example of

Industrial melanism in peppered moth occurred due to natural selection . The significant reason for this is (a) the light coloured white moths could not be noticed by predatory birds after deposition of soots on bark of trees (b) mutation in light coloured moths due to increase in industrial pollution (c) advantageous selection of black moths on tree in polluted areas, resulting in increase population of black moths (d) advantageous selection of white moths on tree in polluted areas, resulting in increased population of white moths

The population of grey coloured Biston betularia, were almost replaced by the black variety during the industrial revolution in England. Explain the mechanism involved.

In the case of peppered moth (Biston betularia) the black-coloured from became dominant over the light-coloured form in England during industrial revolution. This is an example of
