Xelga [282]

In the late 1800s, the emphasis on a biological cause of mental disorder ironically resulted in reduced interest in treatments for mental patients because it was thought that mentally ill were possessed by or in need of religion.

The biological causes of mental disorders include genetics, prenatal damage, infections, exposure to toxins, brain defects, and substance abuse.

In the late century the emphasis on the treatment of the mentally not even existed. They were relegated to prisons or almshouses, with dirty conditions.

Help!!!!!!!!!!! Give the date the colony was founded and who it was founded by.
tester [92]

Give the date the colony was founded and who it was founded by. The main reason it was founded and the climate and geographic characteristics (e.g, hot summers, long winters, near ocean, rivers….) of the colony. The main source(s) of income and how the climate or location impacted that.whether or not slave labor was used in the colony is explained below

Explanation:

1.The first colony was founded at Jamestown, Virginia, in 1607. Many of the people who settled in the New World came to escape religious persecution. The Pilgrims, founders of Plymouth, Massachusetts, arrived in 1620. In both Virginia and Massachusetts, the colonists flourished with some assistance from Native Americans.

2.Motivations for colonization: English colonies popped up along the eastern seaboard for a variety of reasons. The New England colonies were founded to escape religious persecution in England. ... The Middle colonies were also called the “Breadbasket colonies” because of their fertile soil, ideal for farming.Queen Elizabeth wanted to establish colonies in the Americas in order to grow the British Empire and to counter the Spanish. ... Many of the colonies were founded by religious leaders or groups looking for religious freedom.A colony is a territory under the immediate complete political control and occupied by settlers of a state, distinct from the home territory of the sovereign. For colonies in antiquity, city-states would often found their own colonies.

3.The Middle colonies spanned the Mid-Atlantic region of America and were temperate in climate, with warm summers and cold winters. Geography ranged from coastal plains along the coastline, piedmont (rolling hills) in the middle, and mountains farther inland. This area had good coastal harbors for shipping.

4.Human basic needs, such as food, water, health, and shelter, are affected by climate. Changes in climate may threaten these needs with increased temperatures, sea level rise, changes in precipitation, and more frequent or intense extreme events. Climate change will affect individuals and groups differently.climate change would increase income inequalities between and within countries. a small increase in global mean temperature (up to 2 °C, measured against 1990 levels) would result in net negative market sector in many developing countries and net positive market sector impacts in many developed countries.

5,In 1619, Dutch traders brought African slaves taken from a Spanish ship to Point Comfort; in North America, the Africans were also generally treated as indentured servants in the early colonial era. Several colonial colleges held enslaved people as workers and relied on them to operate.
