In fact, there was an eighth province, the County of Drenthe, but this area was so poor it was exempt from paying federal taxes and as a consequence was denied representation in the States General. Each province was governed by the Provincial States, the main executive official (though not the official head of state) was a raadspensionaris. In times of war, the stadtholder, who commanded the army, would have more power than the raadspensionaris.
What was the stateholder denied by its tax exemption?

In theory, the stadtholders were freely appointed by and subordinate to the states of each province. However, in practice the princes of Orange of the House of Orange-Nassau, beginning with William the Silent, were always chosen as stadtholders of most of the provinces. Zeeland and usually Utrecht had the same stadtholder as Holland.
What are two things that define the princes in theory?

The framers of the US Constitution were influenced by the Constitution of the Republic of the United Provinces, as Federalist No. 20, by James Madison, shows. Such influence appears, however, to have been of a negative nature, as Madison describes the Dutch confederacy as exhibiting "Imbecility in the government; discord among the provinces; foreign influence and indignities; a precarious existence in peace, and peculiar calamities from war." Apart from this, the American Declaration of Independence is similar to the Act of Abjuration, essentially the declaration of independence of the United Provinces, but concrete evidence that the former directly influenced the latter is absent.

In the Union of Utrecht of 20 January 1579, Holland and Zeeland were granted the right to accept only one religion (in practice, Calvinism). Every other province had the freedom to regulate the religious question as it wished, although the Union stated every person should be free in the choice of personal religion and that no person should be prosecuted based on religious choice. William of Orange had been a strong supporter of public and personal freedom of religion and hoped to unite Protestants and Catholics in the new union, and, for him, the Union was a defeat. In practice, Catholic services in all provinces were quickly forbidden, and the Reformed Church became the "public" or "privileged" church in the Republic.
When was every other province only permitted to accept Calvinism in practice?

During the Republic, any person who wished to hold public office had to conform to the Reformed Church and take an oath to this effect. The extent to which different religions or denominations were persecuted depended much on the time period and regional or city leaders. In the beginning, this was especially focused on Roman Catholics, being the religion of the enemy. In 17th-century Leiden, for instance, people opening their homes to services could be fined 200 guilders (a year's wage for a skilled tradesman) and banned from the city. Throughout this, however, personal freedom of religion existed and was one factor – along with economic reasons – in causing large immigration of religious refugees from other parts of Europe.

In the first years of the Republic, controversy arose within the Reformed Church, mainly around the subject of predestination. This has become known as the struggle between Arminianism and Gomarism, or between Remonstrants and Contra-Remonstrants. In 1618 the Synod of Dort tackled this issue, which led to the banning of the Remonstrant faith.

Symbiosis
Symbiosis (from Greek σύν "together" and βίωσις "living") is close and often long-term interaction between two different biological species. In 1877 Albert Bernhard Frank used the word symbiosis (which previously had been used to depict people living together in community) to describe the mutualistic relationship in lichens. In 1879, the German mycologist Heinrich Anton de Bary defined it as "the living together of unlike organisms."

Symbiosis
Symbiosis (from Greek σύν "together" and βίωσις "living") is close and often long-term interaction between two different biological species. In 1877 Albert Bernhard Frank used the word symbiosis (which previously had been used to depict people living together in community) to describe the mutualistic relationship in lichens. In 1879, the German mycologist Heinrich Anton de Bary defined it as "the living together of unlike organisms."
What year did Albert Bernhard Frank agree to define "symbiosis" as "the living together of unlike organisms."?

Symbiosis
The definition of symbiosis has varied among scientists. Some believe symbiosis should only refer to persistent mutualisms, while others believe it should apply to any type of persistent biological interaction (in other words mutualistic, commensalistic, or parasitic). After 130 years of debate, current biology and ecology textbooks now use the latter "de Bary" definition or an even broader definition (where symbiosis means all species interactions), with the restrictive definition no longer used (in other words, symbiosis means mutualism).
How long did it take for scientists to discover symbiosis?

Symbiosis
Some symbiotic relationships are obligate, meaning that both symbionts entirely depend on each other for survival. For example, many lichens consist of fungal and photosynthetic symbionts that cannot live on their own. Others are facultative (optional): they can, but do not have to live with the other organism.

Symbiosis
Symbiotic relationships include those associations in which one organism lives on another (ectosymbiosis, such as mistletoe), or where one partner lives inside the other (endosymbiosis, such as lactobacilli and other bacteria in humans or Symbiodinium in corals). Symbiosis is also classified by physical attachment of the organisms; symbiosis in which the organisms have bodily union is called conjunctive symbiosis, and symbiosis in which they are not in union is called disjunctive symbiosis.

Endosymbiosis is any symbiotic relationship in which one symbiont lives within the tissues of the other, either within the cells or extracellularly. Examples include diverse microbiomes, rhizobia, nitrogen-fixing bacteria that live in root nodules on legume roots; actinomycete nitrogen-fixing bacteria called Frankia, which live in alder tree root nodules; single-celled algae inside reef-building corals; and bacterial endosymbionts that provide essential nutrients to about 10%–15% of insects.

Symbiosis
Mutualism or interspecies reciprocal altruism is a relationship between individuals of different species where both individuals benefit. In general, only lifelong interactions involving close physical and biochemical contact can properly be considered symbiotic. Mutualistic relationships may be either obligate for both species, obligate for one but facultative for the other, or facultative for both.

Symbiosis
A large percentage of herbivores have mutualistic gut flora that help them digest plant matter, which is more difficult to digest than animal prey. This gut flora is made up of cellulose-digesting protozoans or bacteria living in the herbivores' intestines. Coral reefs are the result of mutualisms between coral organisms and various types of algae that live inside them. Most land plants and land ecosystems rely on mutualisms between the plants, which fix carbon from the air, and mycorrhyzal fungi, which help in extracting water and minerals from the ground.
