QUES: Neptune is similar in composition to Uranus, and both have compositions that differ from those of the larger gas giants, Jupiter and Saturn. Like Jupiter and Saturn, Neptune's atmosphere is composed primarily of hydrogen and helium, along with traces of hydrocarbons and possibly nitrogen, but contains a higher proportion of "ices" such as water, ammonia, and methane. However, its interior, like that of Uranus, is primarily composed of ices and rock, and hence Uranus and Neptune are normally considered "ice giants" to emphasise this distinction. Traces of methane in the outermost regions in part account for the planet's blue appearance.

What gas besides oxygen makes up the atmosphere of Neptune?

QUES: The existence of a "global carrying capacity", limiting the amount of life that can live at once, is debated, as is the question of whether such a limit would also cap the number of species. While records of life in the sea shows a logistic pattern of growth, life on land (insects, plants and tetrapods)shows an exponential rise in diversity. As one author states, "Tetrapods have not yet invaded 64 per cent of potentially habitable modes, and it could be that without human influence the ecological and taxonomic diversity of tetrapods would continue to increase in an exponential fashion until most or all of the available ecospace is filled."

What limits the amount of habitable modes on Earth?

QUES: In the United States, an almost extinct dialect of Dutch, Jersey Dutch, spoken by descendants of 17th-century Dutch settlers in Bergen and Passaic counties, was still spoken as late as 1921. Other Dutch-based creole languages once spoken in the Americas include Mohawk Dutch (in Albany, New York), Berbice (in Guyana), Skepi (in Essequibo, Guyana) and Negerhollands (in the United States Virgin Islands). Pennsylvania Dutch is not a member of the set of Dutch dialects and is less misleadingly called Pennsylvania German.

What's a more accurate name for Pennsylvania Dutch since it's not a Dutch dialect?
What is the answer?
ANS:
Pennsylvania German
