Here is a question about this article: Feeding structures in the mouth region vary widely, and have little correlation with the animals' diets. Many polychaetes have a muscular pharynx that can be everted (turned inside out to extend it). In these animals the foremost few segments often lack septa so that, when the muscles in these segments contract, the sharp increase in fluid pressure from all these segments everts the pharynx very quickly. Two families, the Eunicidae and Phyllodocidae, have evolved jaws, which can be used for seizing prey, biting off pieces of vegetation, or grasping dead and decaying matter. On the other hand, some predatory polychaetes have neither jaws nor eversible pharynges. Selective deposit feeders generally live in tubes on the sea-floor and use palps to find food particles in the sediment and then wipe them into their mouths. Filter feeders use "crowns" of palps covered in cilia that wash food particles towards their mouths. Non-selective deposit feeders ingest soil or marine sediments via mouths that are generally unspecialized. Some clitellates have sticky pads in the roofs of their mouths, and some of these can evert the pads to capture prey. Leeches often have an eversible proboscis, or a muscular pharynx with two or three teeth.
What is the answer to this question: What do some annelids have 'crowns' of?

So... palps covered in cilia

Here is a question about this article: Philip II of Spain decreed the change from the Julian to the Gregorian calendar, which affected much of Roman Catholic Europe, as Philip was at the time ruler over Spain and Portugal as well as much of Italy. In these territories, as well as in the PolishLithuanian Commonwealth (ruled by Anna Jagiellon) and in the Papal States, the new calendar was implemented on the date specified by the bull, with Julian Thursday, 4 October 1582, being followed by Gregorian Friday, 15 October 1582. The Spanish and Portuguese colonies followed somewhat later de facto because of delay in communication.
What is the answer to this question: Why did the Spanish colonies lag behind in adopting the calendar?
****
So... delay in communication

Here is a question about this article: The Times Literary Supplement (TLS) first appeared in 1902 as a supplement to The Times, becoming a separately paid-for weekly literature and society magazine in 1914. The Times and the TLS have continued to be co-owned, and as of 2012 the TLS is also published by News International and cooperates closely with The Times, with its online version hosted on The Times website, and its editorial offices based in Times House, Pennington Street, London.
What is the answer to this question: What is the name of the supplement that first appeared in 1902 as a supplement to The Times?

So...
