Question: In domestic dogs, sexual maturity begins to happen around age six to twelve months for both males and females, although this can be delayed until up to two years old for some large breeds. This is the time at which female dogs will have their first estrous cycle. They will experience subsequent estrous cycles biannually, during which the body prepares for pregnancy. At the peak of the cycle, females will come into estrus, being mentally and physically receptive to copulation. Because the ova survive and are capable of being fertilized for a week after ovulation, it is possible for a female to mate with more than one male.

Question: The most famous reformer of Estonian, Johannes Aavik (1880–1973), used creations ex nihilo (cf. ‘free constructions’, Tauli 1977), along with other sources of lexical enrichment such as derivations, compositions and loanwords (often from Finnish; cf. Saareste and Raun 1965: 76). In Aavik’s dictionary (1921), which lists approximately 4000 words, there are many words which were (allegedly) created ex nihilo, many of which are in common use today.

Question: Marshall's words and future court decisions gave Congress much latitude in delegating powers. It was not until the 1930s that the Supreme Court held a delegation of authority unconstitutional. In a case involving the creation of the National Recovery Administration called A.L.A. Schechter Poultry Corp. v. United States, 295 U.S. 495 (1935), Congress could not authorize the president to formulate codes of "fair competition." It was held that Congress must set some standards governing the actions of executive officers. The Court, however, has deemed that phrases such as "just and reasonable," "public interest" and "public convenience" suffice.

Question: John grew up to be around 5 ft 5 in (1.68 m) tall, relatively short, with a "powerful, barrel-chested body" and dark red hair; he looked to contemporaries like an inhabitant of Poitou. John enjoyed reading and, unusually for the period, built up a travelling library of books. He enjoyed gambling, in particular at backgammon, and was an enthusiastic hunter, even by medieval standards. He liked music, although not songs. John would become a "connoisseur of jewels", building up a large collection, and became famous for his opulent clothes and also, according to French chroniclers, for his fondness for bad wine. As John grew up, he became known for sometimes being "genial, witty, generous and hospitable"; at other moments, he could be jealous, over-sensitive and prone to fits of rage, "biting and gnawing his fingers" in anger.[nb 3]
