There are several factors for establishing a civilization which are:
Big population centers: These help people survive with the help of each other, like farmers can grow and sell in these areas etc.
Monumental Architecture or Art: This will be identified as their legacy
Record Keeping: This can be a language or any other recording system to help record the history and traditions.
System of administering areas: Help run the place smoothly.
Labor division: Various people are skilled at various jobs, to do a certain job a skilled laborer is required.
Social Class System: It can be based on wealth as well as the type of work performed.
In order to become a civilization a society needs to bring all these attributes in and work towards a common goal of achieving them.

Answer: Three effects that European imperialism had on Africa included a more structured political system with an organized government, the development of industrial technology and the idea of nationalism, which led to wars and revolutions later on.Europeans changed the economy from a model of producing foods for need to mainly the production of cash crops. All crops produced by Africans were exported and prices were set by the colonies. Africans were not allowed to grow these cash crops to benefit themselves.Imperialism adversely affected the colonies. Under foreign rule, native culture and industry were destroyed. Imported goods wiped out local craft industries. By using colonies as sources of raw materials and markets for manufactured goods, colonial powers held back the colonies from developing industries.
hope this helps have a nice day❤️
Explanation:
Sedatives and Hypnotics depress the central nervous system by interfering with the transmission of nerve impulses.
Like alcohol, sedatives and hypnotics are depressants that depress the central nervous system. Since long-term exposure to alcohol can lead to the development of depression, chronic use of sedatives and hypnotics, as demonstrated by several neurobiological and imaging studies
Long-term use of sedatives can cause side effects such as Psychiatric disorders such as anxiety.
It has been suggested that treating depression and anxiety with sedatives/hypnotics, especially benzodiazepines, may reduce the risk in the first few weeks. Sedatives/hypnotics also have inhibitory and disinhibitory properties, but these may increase the risk
