Answer:
When the first World Book was published in 1917, there were only two independent countries in Africa: Abyssinia (now Ethiopia) and Liberia. Together, they made up less than 5 percent of the land area of the continent. The rest of Africa was divided into colonies controlled by the European nations of Belgium, France, Germany, Italy, Portugal, Spain, and the United Kingdom.
Organized groups in some African colonies began demanding self-government early in the 1900’s. But a mass independence movement did not take shape until after World War II (1939-1945).
Some countries gained their independence relatively peacefully. In 1951, Libya, which was an Italian colony in 1917, became the first country in Africa to gain independence. In 1956, France granted Morocco and Tunisia independence. That same year, the United Kingdom granted Sudan independence as well. Other countries saw much bloodshed before their independence was granted. In Algeria, a bloody revolt raged against the French from 1954 until the country won independence in 1962. In Kenya, members of a movement called Mau Mau revolted against British control in the 1950’s. The revolt failed, but it contributed to Kenya’s eventual decolonization in 1963.
Explanation: Today, Africa is divided into 54 independent countries. Several European countries still control a few small islands: the Madeira Islands (controlled by Portugal), Mayotte and Réunion (France), and Saint Helena (United Kingdom).
A star can be classified according to the following: main sequence, giants, and supergiants. On the other hand, the spectral class of a star is classified according to their temperature, absolute magnitude and solar luminosity.

Answer:
Miller considers living systems as a subset of all systems. Living systems according to Parent (1996) are by definition "open self-organizing systems that have the special characteristics of life and interact with their environment. This takes place by means of information and material-energy exchanges.
Explanation:
Answer:
Trenches are not found int he Appalachian mountain province today.
Explanation:
1 is not correct because there is an abundance of metamorphic rocks, which is not weird considering the age of this mountain range.
2 is not correct because this mountain range has been close to intense volcanism during its formation, so it still has some of the volcanic rocks preserved.
3 is not correct because there are a lot of folded and faulted mountain ridges, many of which are visible at the surface today.
4 is not correct because these mountains rose from the ocean, so there are remnants of an ancient floor at places.
5 is not correct because with the erosion over hundreds of millions of years, valleys have been gradually formed at the periphery of this mountain range.
6 is not correct because the top layers of this e range are predominantly made of sedimentary rocks.
7 is correct because the trenches that existed in this area have disappeared a couple of hundreds of millions of years ago, mainly because the area has been gradually moving away from the tectonic boundaries and became an area that is tectonically inactive.
