Asia, Africa, Australia, North America, South America, Europe and Antarctica.

Africa - 53 countries

Asia - 48 countries

Europe - 45 countries

The Holocaust, also referred to as the Shoah,[b] was a genocide during World War II in which Nazi Germany, aided by its collaborators, systematically murdered approximately 6 million European Jews, around two-thirds of the Jewish population of Europe, between 1941 and 1945.

The Holocaust originated in Nazi Germany in the late 1930s and eventually spread throughout Central and Eastern Europe into countries invaded and occupied by Germany during World War II.

The Nazis were racists and believed their race was more important. Nazis believed that the jews were a problem. Many of the non-germans that were living on the land were sent to concentration camps.

The main place it took place was eastern Germany and Poland. The Holocaust was largely comprised of a vast network of concentration camps in countries including Germany, Poland, Austria, Ukraine, Norway, the Czech Republic, Slovakia, Belarus, the Netherlands, and France.

If the percent change in quantity demanded is less than the percent change in price, economists label the demand for the good as inelastic.

A good that is inelastic does not have very stretchy demand. In economic terms, the quantity demanded does not change a lot when the price changes.

So, if the price of a good increases by 10 percent and the quantity demanded decreases by only 5 percent or less than 10, that good is said to have inelastic demand.

Hence, in this case, consumers are not considered very sensitive, or responsive, to a change in the price of that good.

Squirrels typically build leaf nests in the summer by weaving together small branches they've gnawed off of trees. These nests are lined with grass, moss, leaves and pine needles. Both male and female gray squirrels of all ages participate in building dens.
