Can you think of an experiment to test the hypothesis that being light or dark makes a difference in the survival rates of peppered moths?

I remember years ago reading up about industrialisation and how pollution caused many trees and whatnot to darken considerably with the smog, exposing the light peppered moths and giving the dark peppered moths a better chance of survival.

How do peppered moths after the Industrial Revolution show the process of natural selection?
The peppered moth had white bodies and wings, peppered with black. This coloration blended well into the original British countryside, hiding them from their predator the birds. Factories of the early industrial revolution covered everything with soot. Now the white stood out against the black surroundings making them easy targets for birds. Over time the white moths were wiped out. But, a few of them were darker in color, these survived and multiplied such that the white peppered moth was replaced buy the dark ones.Black moths were selected for when the trees turned black.the moths with the high fitness were selected forThe black moths were more fit for survival, so their phenotype frequency increased.

Does insulting your plants affect them?
Insulting your plants won't make any difference to them they are pretty thick skinned. If you mean insulating them then this makes a difference when the conditions are too cold for survival.
How does natural selection account for every complexity of life if certain biological advantages are too insignificant to determine survival or death?
Natural selection is based on mutation. Every being is born with mutations. Some are visible and most of them not at all and make no difference for survival. Those who are insignificant for reproduction or survival are sometimes also passed on to the next generation and to the next and so on. Over a long period of time this can make a difference although it might be not important for death or survival. Some characteristics might have had an advantage but is not obvious for us to say.
How does a white moth illustrate natural selection?
The colour of the peppered moth is often used as an example of natural selection. During the Industrial Revolution, the surfaces on which peppered moths frequently settle became increasingly stained with soot from the chimneys of factories, darkening them. Lighter-coloured moths would more easily be seen on these darkened surfaces by predators, and so the chances of survival were less for lighter moths than for darker moths; having a darker colour bestowed a reproductive advantage. As a result, the average colour for the population as a whole became darker.
What is the difference between the human brain and a frogs brain?
The main difference is in the association area. The association area is 90% of the human brain. It is what allows complex thought instead of just survival instinct.
What difference will give some individuals a better chance of survival?
It depends on survival of what. Surviving chances after an illness or operation are mostly influenced by someone's age (preferably: young) and general condition (healthy, trained, non-smoker etc.).
Which tpe of selection occurred among the peppered moths of England following the Industrial Revolution that stained londons tree trunks dark brown?
The peppered moths of England underwent directional selection following the Industrial Revolution. Prior to the pollution caused by industrialization, lighter-colored moths were more common and better camouflaged on the light-colored tree trunks. However, as pollution darkened the tree trunks, the darker moths had a survival advantage and their population increased.
