Explanation:
In 1811 the French chemist Bernard Courtois obtained a violet vapour by heating seaweed ashes with sulfuric acid as a by-product of the manufacture of saltpetre. This vapour condensed to a black crystalline substance, which he called “substance X.” In 1813 British chemist Sir Humphry Davy, who was passing through Paris on his way to Italy, recognized substance X as an element analogous to chlorine; he suggested the name iodine from the Greek word ioeides, “violet coloured.”

Occurrence and distribution
Iodine is never found in nature uncombined, and it is not concentrated sufficiently to form independent minerals. It is present in seawater, but sparingly, as the iodide ion, I−, to the extent of approximately 50 mg per metric ton (0.0016 ounce per ton) of seawater. It is also formed in seaweeds, oysters, and cod livers. Sodium iodate (NaIO3) is contained in crude Chile saltpetre (sodium nitrate, NaNO3). The human body contains iodine in the compound thyroxine, which is produced in the thyroid gland.
The only naturally occurring isotope of iodine is stable iodine-127. An exceptionally useful radioactive isotope is iodine-131, which has a half-life of eight days. It is employed in medicine to monitor thyroid gland functioning, to treat goitre and thyroid cancer, and to locate tumours of the brain and of the liver. It is also used in investigations to trace the course of compounds in metabolism. Several iodine compounds are used as contrast mediums in diagnostic radiology. In aqueous solution even minute amounts of iodine in the presence of starch produce a blue-black colour

Describe 3-5 of the divisions of labor (jobs) in the economy of the New England colonies. VOLIS
Answer:
Labor and Trade in Colonial America
Common Misconceptions
When textbooks discuss colonial labor practices, they most often associate the concept of labor with male work done outside the physical boundaries of the home—in fields; on docks; in warehouses; on ships. Labor is associated with creating goods for market, allowing men to participate in the "triangle trade"—a network of trade relationships in which raw materials flowed from the Americas to Europe, manufactured goods moved from Europe to Africa, and enslaved Africans were shipped back to the Americas. Yet this framing oversimplifies the complex history of labor in colonial America. It overlooks female labor as central, not peripheral, to the survival of familial and colonial economies alike. It ignores the fact that different patterns of labor existed in Native communities, and that non-Native opinions of Native labor practices influenced colonial Indian policy. It also oversimplifies the complex web of international trade relationships that wove together the Atlantic world. Commodities never flowed in one direction; goods, people, and services might depart from, and end their journey at, any number of Atlantic world ports. In the western contemporary world we are used to thinking of work as something done for wages outside the home. This distinction did not hold for the vast majority of laborers in colonial America. Colonial America was overwhelmingly rural, and North or South, households were made up of a dwelling place for a family (which often included servants and slaves), a garden, shelter for livestock, and fields for crops. While it was rarely their primary responsibility, many free women worked in the fields alongside their husbands, fathers, and brothers, as well as the household's male and female indentured servants or slaves. Some of the raw materials produced outside the walls of the family's dwelling place might go to market, but most came back into the home to be turned into clothing or food, or perhaps bartered for services with neighbors.
Native Americans: Encounters and Labor Systems
Many textbooks marginalize the history of American Indian communities in this period, noting their presence only in times of war. Violence did occur; pitched battles were fought over land ownership and in defense of ways of life threatened by European settlers and disease. Yet there were many more neutral encounters between Native and non-Native people than textbooks would have us believe. In those encounters, many non-Native individuals were exposed to different ways of organizing labor—women as farmers, for example, and men who hunted to provide a family's sustenance, rather than for sport (see Primary Source John White, The Indian Village of Secoton [1585-86]).
...misapprehensions about some Native systems of labor organization fed into European settlers' own sense of racial superiority.
These practices frequently baffled Europeans who, armed with a need to defend their tenancy on lands that did not belong to them, often used them as evidence of Indian people's lack of "civilization." It quickly became a trope that Native women were drudges, that men were wasteful, and worse, beggars. These misapprehensions about some Native systems of labor organization fed into European settlers' own sense of racial superiority. It is important to understand that labor was not only about meeting the everyday needs of a family, or supplying a region's long-term economic health. It could also become the means by which people understood or misunderstood each other, and was used by settlers as a justification for land dispossession and violent confrontation.

Explanation:
What is the difference between a violent crime and a hate crime?
Answer:
A violent crime is committed against someone because of their ethnicity, religion, or other qualities. A hate crime is not prosecuted in a court of law, although a violent crime is. A hate crime can be prosecuted in court, but a violent crime cannot.
Explanation:
The main distinction between a violent crime and a hate crime is the targets and underlying intentions. The distinctions between the two are broken down as follows:
1. Violent Crime: Any criminal conduct that involves the use of force or the threat of force against a person or piece of property is considered a violent crime. It covers a wide variety of crimes, including assault, robbery, murder, sexual assault, and domestic abuse. A violent crime may be motivated by a variety of reasons, such as personal conflicts, monetary gain, or opportunities.
2. Hate Crime: A hate crime, often referred to as a bias crime or bias-motivated crime, is a criminal violation committed against a person, group, or piece of property and is motivated by prejudice or bias based on particular traits of the victim.
Race, ethnicity, religion, sexual preference, gender identity, and other protected qualities are examples of these characteristics. Hate crimes entail the victim being specifically targeted by the offender because of their perceived affiliation with a certain group or identity.
The motivation and qualities of the target are the main distinctions between a violent crime and a hate crime. While there are many unrelated factors that might lead to a violent crime, regardless of the victim's identity, a hate crime is specifically motivated by prejudice or bigotry towards a specific group or characteristic.
Due to their effects on the targeted population and the ability to cause fear and intimidation in those besides the immediate victim, hate crimes are thought to be particularly atrocious.

Explanation:

Answer:
Explanation: Personality is defined as the characteristic sets of behaviors, cognitions, and emotional patterns that evolve from biological and environmental factors. While there is no generally agreed upon definition of personality, most theories focus on motivation and psychological interactions with one's environment. Trait-based personality theories, such as those defined by Raymond Cattell, define personality as the traits that predict a person's behavior. On the other hand, more behaviorally-based approaches define personality through learning and habits. Nevertheless, most theories view personality as relatively stable. The study of the psychology of personality, called personality psychology, attempts to explain the tendencies that underlie differences in behavior. Many approaches have been taken on to study personality, including biological, cognitive, learning and trait-based theories, as well as psychodynamic, and humanistic approaches. Personality psychology is divided among the first theorists, with a few influential theories being posited by Sigmund Freud, Alfred Adler, Gordon Allport, Hans Eysenck, Abraham Maslow, and Carl Rogers.
