The term Nederduits, however introduced new confusion, since the non standardised dialects spoken in the north of Germany came to be known as Niederdeutsch as well, and thus the Duits reference in the name was dropped, leading to Nederlands as designation to refer to the Dutch language. The repeated use of Neder (or "low") to refer to the Dutch language is a reference to the Netherlands' downriver location at the RhineMeuseScheldt delta near the North Sea, harking back to Latin nomenclature, e.g. Germania Inferior. See also: Netherlands (toponymy).

The Netherlands are "low" because of their placement near what delta by the North Sea?
Answer: RhineMeuseScheldt delta

The fluid in the coelomata contains coelomocyte cells that defend the animals against parasites and infections. In some species coelomocytes may also contain a respiratory pigment red hemoglobin in some species, green chlorocruorin in others (dissolved in the plasma) and provide oxygen transport within their segments. Respiratory pigment is also dissolved in the blood plasma. Species with well-developed septa generally also have blood vessels running all long their bodies above and below the gut, the upper one carrying blood forwards while the lower one carries it backwards. Networks of capillaries in the body wall and around the gut transfer blood between the main blood vessels and to parts of the segment that need oxygen and nutrients. Both of the major vessels, especially the upper one, can pump blood by contracting. In some annelids the forward end of the upper blood vessel is enlarged with muscles to form a heart, while in the forward ends of many earthworms some of the vessels that connect the upper and lower main vessels function as hearts. Species with poorly developed or no septa generally have no blood vessels and rely on the circulation within the coelom for delivering nutrients and oxygen.

What do annelids without septa have to use for circulation?
Answer: circulation within the coelom

The Iranian languages or Iranic languages form a branch of the Indo-Iranian languages, which in turn are a branch of the Indo-European language family. The speakers of Iranian languages are known as Iranian peoples. Historical Iranian languages are grouped in three stages: Old Iranian (until 400 BCE), Middle Iranian (400 BCE 900 CE), and New Iranian (since 900 CE). Of the Old Iranian languages, the better understood and recorded ones are Old Persian (a language of Achaemenid Iran) and Avestan (the language of the Avesta). Middle Iranian languages included Middle Persian (a language of Sassanid Iran), Parthian, and Bactrian.

What is an example of a Sassanid language?
