Acid rain can cause many problems, such as stripping paint and burning skin, but I believe the answer you are looking for is "decay," which is the process that occurs when an organism decomposes.
Answer:
Organism having the suitable traits appears more in the population.
Explanation:
Natural selection is a non-random process in the biological traits becomes less or more common in the population due to the different rate of survival of their bearer or their differential reproduction.
Natural selection leads to evolution because those organisms are selected to survive and reproduce which are having those traits that are better suited to a certain set of environmental conditions over others. As a result, the number of these organisms increases over time and they appear more in the population.
So natural selection leads to evolution as an organism having the suitable traits appears more in the population.
Answer:
North Pole
Explanation:
The surface of the Earth is inclined perpendicular to the sunlight (as in the left hand side of figure 2), and so receives the maximum amount of sunlight per square area. The situation is most extreme at the north and south poles. At the north pole, the season is one long,cold night which last for six months.
