Answer:
Natural selection leads to evolution due to the way reproduction works. In the example of European moths during the industrial revolution, we can see this clearly. When the industrial revolution was going, there was more pollution, hence darkening the skies and leaving ash. Moths, which before were white with occasional black spots dominated the area until pollution effected their environment. Whiter moths were eaten by bird who could easily see them against the black trees and skies. These moths could no longer reproduce, they were dead. Moths with more black could survive longer to reproduce because they were harder to see. As time went along, the moths turned mostly black, showing an example of evolution.

The answer is <span>b. Swamps are deeper and have a larger proportion of surface water than marshes, and bogs have acidic groundwater.
Bogs, marshes, and swamps are types of wetlands. Swamps and marshes are mineral soil wetlands. Swamps are deeper and with a larger proportion of surface water than marshes. Usually, swamps develop from marshes that fill in. Bogs are organic soil wetlands. They are acid areas with acidic groundwater.</span>
D.
They have the same number of protons as electrons.
Explanation:
Protons are found in the nucleus of the atom and have a positive charge while electrons orbit around the nucleus and have a negative charge. Usually, in a neutral atom of an element, the number of protons is equal to the number of electrons. This is why the atom has no charge because the positive and negative charges cancel out. When an atom loses an electron its charge turns positive while when it gains an electron its charge turns negative.
