Evolution is caused by genetic mutations that become favorable for survival.
For example if a bird has a mutation that gives it a longer beak and it lives in an environment in which a longer beak lets the bird catch more food- the longer beak becomes a favorable trait.
Now the bird is able to survive “better” thus it lives longer(due to its ability to catch more food). Because of this it reproduces more and passes the trait on to its offspring.
Overtime this mutation takes over the population of birds in the area.

Answer:
B. Sulfur
Explanation:
Acid rain is <u>the result of sulfur dioxide emissions combined with nitroxen oxides.</u> This occurs when both compounds interact with water and oxygen (and other molecules) that are already present in the atmosphere.
This phenomenon is extremely dangerous for both humans, fauna, and flora, especially when it comes to aquatic organisms. <u>Some freshwater fish species, for instance, are not able to grow or develop due to the increased pH. In other cases, when the pH is even lower, organisms are not able to cope and eventually die.</u>
Therefore, a reduction in atmospheric concentrations of sulfure could reduce acid rain and return rain to its normal pH.
