It will take 15 years for Della to be in the same risk of
non-smoking persons in risk of cardiovascular disease. As you quit smoking, the
lungs will start to purify itself, but it will take some time. On the other
hand, it cannot be assured that the lungs may be totally restored, more or less
it would just be clean over a period of time.
Mutation is the primary cause of all genetic variation. Mutation is important as the first step in evolution, as it produces a new sequence of DNA for a particular gene, producing a new allele. Recombination, through intragenic recombination, may also generate a new DNA sequence (a new allele) for a particular gene.
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.
The best option is A Coriolis Effect. The Coriolis effect is most apparent in the path of an object moving longitudinally.
