<u>Explanation:</u>

The supreme court of United States permitted states to segregate people of color by applying earlier laws on civil rights, when African Americans knocked at supreme court to protect their rights under the constitution.

A new Louisiana law in 1890 needed railroads to give "equal but separate accommodations on the basis of colored races" this blasted the New Orleans' black community therefore "Plessy v. Ferguson" case got stand and decision of supreme court came as  "separate but equals". Plessy is commonly refereed as one of the worst decisions in the U.S. History of the Supreme Court. Later series of decisions came which overruled the "separate but equal" as found unconstitutional like "1954 case Brown v. Board of Education".

Debora [2.8K]

Answer:

Detailed answer is given below

Explanation:

In each phase of growth, your child is learning in several areas at the same time. A young child is learning to walk (physical), learns colors (intellectual), feels uncomfortable with strangers (social), expresses feelings of independence (emotional) and realizes the disapproval of adults for bad behavior (moral) .

There are five areas of human development:

Physical development: variations in the size, figure and bodily maturity of the body, including physical abilities and coordination.

Intellectual development: learning and the use of language; the ability to reason, solve problems and organize ideas; It is related to the physical growth of the brain.

Social development: the process of obtaining the knowledge and skills necessary to interact successfully with others.

Emotional development: emotional feelings and responses to events; changes in the understanding of one's feelings and the appropriate ways of expressing them.

Moral development: the growing understanding of right and wrong, and the change in behavior caused by that understanding; It is sometimes called conscience.
