The answer is d. The population of light-colored moths decreased and the population of dark-colored moths increased.

<span>Peppered moth color variation is a good example of natural selection. During the Industrial revolution, due to pollution, trees become darker in the urban area. Light-colored moths were, thus, easy prey. The dark-colored moths were able to camouflage on dark trees and avoid predators. The phenomenon is known as industrial melanism. So, in polluted urban areas, the number of dark-colored peppered moths increased. In the clean environment, were much effective in hiding from predators and they outnumbered the dark-colored moths.</span>

notka56 [123]

The correct answer is - B. Britain was more densely populated in 1911 than in 1701.

Britain had had a steady rise in its population after the Middle Ages finished, and at the beginning of 18th century its population was significantly larger. Than it was noticed a big increase in the population, and this was mainly due to the industrial revolution.

Why do you think government officials (and the public in general) were opposed to labor unions in the beginning? Why do you thin
Lelechka [254]

I'll answer this question with some of my general knowledge. Let me know if I helped you or not.


I believe officials were opposed to labor unions when they began to acknowledge how much of a threat it would be to manufacturing and other sorts of jobs. Labor Unions are similar to going on strike, or protesting something. With protesting laborers, businesses and factories would drop in revenue and would become unproductive. They would end up having to increase pay and improve working conditions to earn their workers back. This is equivalent to the loss of income for businesses.

I believe times changed in the 1930 because the American economy was extremely poor. The 1930's was the time of The Great Depression, multiple stock market crashes, and The Dust Bowl. These events hit hard and poverty became <em>wide spread. </em>


Hope I answered your question :)
