The observations about the number of white winged and dark-winged moths in England during different environmental conditions shows that:
1 Predators can't spot a moth against contrasting background
2 No variant is completely wiped out
3 The areas where industrialisation did not occur, the count of melanic moths was high
4 Industrialisation did not have any effect on the number of moths
Explanation:
Due to industrialization, the air pollution increased and lichens growth is declined so the black colored moths are well camouflaged themselves into the bark of trees that are covered by the industrial pollution and reproduce but white peppered moth are visible and more visible to predators so naturally declined. This is caused as humans evolve themselves but that increase the pollution and lead to a wrong or negative way for the moth.

Evolutionary convergence is characterized by
1 Development of characteristics by random mating
2 Development of a common set of characteristics in group of different ancestry
3 Replacement of common characteristics in different groups
4 Development of dissimilar characteristics in closely related groups
Explanation:
Convergent evolution is development of similar adaptive functional structures in unrelated groups of organisms. It also shows analogy.

There were more white-winged moths on trees than dark-winged or melanised moths during ____ period in England.
1 1850 s, i.e., after industrialisation set in
2 1920, i.e., before industrialisation set in
3 1850 s, i.e., before industrialisation set in
4 1920, i.e., after industrialisation set in
Explanation:
In a collection of moths made in 1850 s,i.e., before industrialisation set in, it was observed that there were more white-winged moths on trees than dark-winged or melanised moths.

Rocks form sediments and a cross-section of earth's crust indicates (I) The arrangement of sediments one over the other during the long history of earth. (II) It contains fossils of different life-forms who probably died during the formation of the particular sediment.
1 Only I is correct
2 Only II is correct
3 Both are correct
4 Irrelevant statement
Explanation:
Sedimentary rocks cover most of the Earth's rocky surface, but they only make up a very small percentage of the planet's crust. They often contains fossils of plants and animals millions of years old. Limestone is often made from the fossilized remains of ocean life that died millions of years ago. These rocks form layers called strata which can often be seen in exposed cliffs.
