Answer;
Acid rain is mostly a problem in the Northern Hemisphere.
Explanation;
This can be attributed to the fact that the area has a large, densely populated cities and a concentrated number of industrial and power plants in an area. These factors contribute to acidic gases in the environment such as sulfur oxide, nitrous oxide, which mix with rain water to form acidic rain. Additionally, prevailing wind direction which brings with it the pollution from the midwest to the north east.

Answer:
It transmits genetic information to the next generation
Explanation:
DNA stores information on how the cell should be made and ‘run’. This is why it is critical that its integrity is well preserved. Otherwise, mutations on DNA can be lethal to the cell. In higher cells, DNA is protected in the nucleolus. To pass down the genetic information, DNA is replicated by DNA polymerases and then during cell division, either copy of the pair goes to each of the two daughter cells.
Answer:
Many scientists use dichotomous keys to identify plants, animals, and other organisms. They may also use dichotomous keys to identify species, or to determine whether a particular organism has been identified and described before. However, dichotomous keys are not used only to identify organisms.
