Question: The discovery of infrared radiation is ascribed to William Herschel, the astronomer, in the early 19th century. Herschel published his results in 1800 before the Royal Society of London. Herschel used a prism to refract light from the sun and detected the infrared, beyond the red part of the spectrum, through an increase in the temperature recorded on a thermometer. He was surprised at the result and called them "Calorific Rays". The term 'Infrared' did not appear until late in the 19th century.
Is there an answer to this question: What society did Herschel present his work on the red spectrum?

Answer: unanswerable


Question: Grazing organisms may also kill their prey species, but this is seldom the case. While some herbivores like zooplankton live on unicellular phytoplankton and therefore, by the individualized nature of the organism, kill their prey, many only eat a small part of the plant. Grazing livestock may pull some grass out at the roots, but most is simply grazed upon, allowing the plant to regrow once again. Kelp is frequently grazed in subtidal kelp forests, but regrows at the base of the blade continuously to cope with browsing pressure. Animals may also be 'grazed' upon; female mosquitos land on hosts briefly to gain sufficient proteins for the development of their offspring. Starfish may be grazed on, being capable of regenerating lost arms.
Is there an answer to this question: Prey that can regrow leaves or arms have learned to deal with what?

Answer: browsing pressure


Question: The metro leaves the Rodoviária (bus station) and goes south, avoiding most of the political and tourist areas. The main purpose of the metro is to serve cities, such as Samambaia, Taguatinga and Ceilândia, as well as Guará and Águas Claras. The satellite cities served are more populated in total than the Plano Piloto itself (the census of 2000 indicated that Ceilândia had 344,039 inhabitants, Taguatinga had 243,575, whereas the Plano Piloto had approximately 400,000 inhabitants), and most residents of the satellite cities depend on public transportation.
Is there an answer to this question: What do most residents of the Rodoviaria depend on?

Answer: unanswerable


Question: Jehovah's Witnesses believe their highest allegiance belongs to God's kingdom, which is viewed as an actual government in heaven, with Christ as king. They remain politically neutral, do not seek public office, and are discouraged from voting, though individual members may participate in uncontroversial community improvement issues. Although they do not take part in politics, they respect the authority of the governments under which they live. They do not celebrate religious holidays such as Christmas and Easter, nor do they observe birthdays, nationalistic holidays, or other celebrations they consider to honor people other than Jesus. They feel that these and many other customs have pagan origins or reflect a nationalistic or political spirit. Their position is that these traditional holidays reflect Satan's control over the world. Witnesses are told that spontaneous giving at other times can help their children to not feel deprived of birthdays or other celebrations.
Is there an answer to this question: What is one of the Protestant religions that thinks celebrating things other than Jesus are ok?

Answer:
unanswerable
