c. were often the result of civil wars between tribes within a country
Explanation:
As a result of colonial history and rulings in Africa, the borders of the countries did not form naturally by the people of different communities but were made by dividing the land between colonizers and armies.
Because of that, various tribes and ethnic communities were “cut off” from their people, <u>while being stuck in the same legal country with people they did not share values with.</u><u> </u>During the 20th century, this resulted in many problems and fights, as well as wars in different countries.<u> They would be sometimes settled only by the military dictatorship.</u>
Answer:
The DNA must be able to separate its two strands in order to be connected to the sliding clamp.
For this to occur, the action of the protein components: helicase and topoisomerase is necessary.
Explanation:
The sliding clamp is a protein that participates in DNA replication. This protein is responsible for forming a "ring" around the single strand of DNA, allowing the polymer DNA (DNA replicating enzyme) to be firmly suited to the strand and to be able to create the new DNA strands. The sliding clamp is also responsible for the DNA polymerase decoupling from the DNA at the end of replication.
For the sliding clamp to work correctly, it is necessary for the DNA to unravel and release its two strands. This process needs the help of the Helicase enzymes, which are responsible for breaking the hydrogen bonds that hold the two DNA strands together, and, for topoisomerase, which is the enzyme that prevents single strands of DNA from creating torsions in their extension.

Answer:
Explanation:
The population is divided into this “in the labor force”. Thus, the number of adults not in the labor force is 237.8-153.9= 83.9 million. Since the labor force is divided into employed persons and unemployed persons, the number of unemployed persons is 153.9-139.1 = 14.8 million. Thus, the adult population has the following proportions:
