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.
Answer:
Environmental impacts of particles, such as dust and smoke, released from livestock production - impair the visibility, can lead to acid rain, degrade the ecosystem
Environmental impacts of greenhouse gases released from livestock production - increase in atmospheric temperature
Explanation:
Environmental impacts of particles, such as dust and smoke, released from livestock production -
Release of particles such as dust and smoke is referred to as particulate pollution. These particle makes the air unfit for .breathing. If humans inhale it, it will adversely affect the heart and lungs.
These particle impair the visibility, can lead to acid rain, degrade the ecosystem etc.
Environmental impacts of greenhouse gases released from livestock production -
Green house gases will lead to increase in atmospheric temperature
Answer:
Explanation:
The correct answer is (B) Helicase creates the replication fork; single-strand binding proteins keep the single strands from reuniting. The replication fork is established by the enzyme DNA helicase, which separates the two complementary strands of a DNA molecule
