Answer:
Ted born in 1990
Explanation:
There have been many studies conducted by researchers on the onset of puberty. These studies show that puberty has been dropped gradually in decades. Hermann Giddens published their research in which they indicated that the onset of puberty has changed over time and specially in girls as compared to the boys.
The age of the onset has been plunge out over time. The researcher gets data on the onset of puberty that average age in 1860 was 16.6 years old, In 1920 it decreases and stays at 14.6, in the 1950 s it is around 13.1, 1980; 12.5 and in 2010 it was around 10.5. Why our children are going to get early adulthood is still a question.
Answer:
The Black Codes sometimes called Black Laws, where laws governing the conduct of African Americans. The best known of them was passed in 1865 and 1866 by Southern states, after the American Civil War, in order to restrict African Americans' freedom and to compel them to work for low wages. Although Black Codes existed before the Civil War and many Northern states had them, it was the Southern U.S. states that codified such laws in everyday practice. In 1832, James Kent wrote that "in most of the United States, there is a distinction in respect to political privileges, between free white persons and free colored persons of African blood; and in no part of the country do the latter, in point of fact, participate equally with the whites, in the exercise of civil and political rights."

Answer:
There are differences between layers of the earth based on composition and in response to stress.
Explanation:
There are three layers of Earth based on 'chemical composition': the crust, the mantle, and the core. The outermost part is the crust which is less than 1% of Earth by mass. It consists of oceanic crust and continental crust. The mantle is hot and the last layer core is mostly composed of iron metal.
The physical behavior of earth depends on how much pressure it faces and its repose to stress. As we go deep inside the earth, the pressure and temperature increase. Lithosphere, Asthenosphere, Upper and lower mesosphere, outer and inner core are layers of Earth subjected to pressure. Lithosphere is the strongest layer. Asthenosphere being weaker than lithosphere.
