Before industrialization it was observed that there were more white winged moths on trees than dark winged moths Why?

Assertion :- In England, before industrialisation, it was observed that there were more white-winged moths on trees than dark-winged or melanised moths. Reason :- White winged moths can survive in non industrialised area.

A. The conditions primitive on earth (before the origin of life) were : low temperature, volcanic storms, reducing atmosphere containing Ch_(4),NH_(3) , etc. B. Cheetah and humans share similarities in the pattern of bones of forelimbs. C. In a collection of moths made in the 1850s i.e., before industrialization set in, it was observed that there were more dark-winged moths on trees than white-winged moths. D. Branching descent and natural selection are the two key concepts of Darwinian theory of evolution. E. The Neanderthal man with a brain size of 1400 cc lived in east and central Asia 25,000-10,000 years ago. Which set of given statements are correct ?

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

How can evolution by natural selection be explained by melanised moths before and after industrialisation in England ?

Taking an example of white-winged moths and dark-winged moths of England in per and post industrialised era, explain evolution by natural selection .

Some experiments were carried out using Croton sp. plants to understand the process of photosynthesis. It was observed that the leaves of the plant exposed to light for longer duration accumulated more starch. However, due to presence of pre-formed starch in the leaves, it was difficult to find the net productivity on a fixed exposure to light source. Therefore, it was necessary to obtain starch free leaves in the plant before starting the experiment. After a period of illumination, the leaves were boiled in alcohol to make them colourless. Which of the following could be used to test the end product stored in the leaves?

However, due to presence of pre-formed starch in the leaves, it was difficult to find the net productivity on a fixed exposure to light source. Therefore, it was necessary to obtain starch free leaves in the plant before starting the experiment. Some of the starch free leaves were coated with wax on both the surfaces. The plant was maintained under normal environmental conditions. At the end of the experiment, the wax coated leaves are likely to show _________.
