Question: Passage: The gut is generally an almost straight tube supported by the mesenteries (vertical partitions within segments), and ends with the anus on the underside of the pygidium. However, in members of the tube-dwelling family Siboglinidae the gut is blocked by a swollen lining that houses symbiotic bacteria, which can make up 15% of the worms' total weight. The bacteria convert inorganic matter such as hydrogen sulfide and carbon dioxide from hydrothermal vents, or methane from seeps to organic matter that feeds themselves and their hosts, while the worms extend their palps into the gas flows to absorb the gases needed by the bacteria. Question: How much of a Siboglinidae's weight is symbiotic bacteria?

Answer: 15%

Question: Passage: Players may only be transferred during transfer windows that are set by the Football Association. The two transfer windows run from the last day of the season to 31 August and from 31 December to 31 January. Player registrations cannot be exchanged outside these windows except under specific licence from the FA, usually on an emergency basis. As of the 201011 season, the Premier League introduced new rules mandating that each club must register a maximum 25-man squad of players aged over 21, with the squad list only allowed to be changed in transfer windows or in exceptional circumstances. This was to enable the 'home grown' rule to be enacted, whereby the League would also from 2010 require at least 8 of the named 25 man squad to be made up of 'home-grown players'. Question: Can players be transferred under an emergency outside the transfer windows?

Answer: Player registrations cannot be exchanged outside these windows except under specific licence from the FA, usually on an emergency basis.
