Shortly thereafter, however, Constantine's son, the new Roman Emperor Constantius II, renewed the order for Athanasius's banishment in 338. Athanasius went to Rome, where he was under the protection of Constans, the Emperor of the West. During this time, Gregory of Cappadocia was installed as the Patriarch of Alexandria, usurping the absent Athanasius. Athanasius did, however, remain in contact with his people through his annual Festal Letters, in which he also announced on which date Easter would be celebrated that year.

QUES: Most mutations within genes are neutral, having no effect on the organism's phenotype (silent mutations). Some mutations do not change the amino acid sequence because multiple codons encode the same amino acid (synonymous mutations). Other mutations can be neutral if they lead to amino acid sequence changes, but the protein still functions similarly with the new amino acid (e.g. conservative mutations). Many mutations, however, are deleterious or even lethal, and are removed from populations by natural selection. Genetic disorders are the result of deleterious mutations and can be due to spontaneous mutation in the affected individual, or can be inherited. Finally, a small fraction of mutations are beneficial, improving the organism's fitness and are extremely important for evolution, since their directional selection leads to adaptive evolution.:7.6
What are mutations that have no effect on an organism's phenotype called?

ANS: silent mutations

On 7 January 2009, The Sun ran an exclusive front page story claiming that participants in a discussion on Ummah.com, a British Muslim internet forum, had made a "hate hit list" of British Jews to be targeted by extremists over the Gaza War. It was claimed that "Those listed [on the forum] should treat it very seriously. Expect a hate campaign and intimidation by 20 or 30 thugs." The UK magazine Private Eye claimed that Glen Jenvey, a man quoted by The Sun as a terrorism expert, who had been posting to the forum under the pseudonym "Abuislam", was the only forum member promoting a hate campaign while other members promoted peaceful advocacy, such as writing 'polite letters'. The story has since been removed from The Sun's website following complaints to the UK's Press Complaints Commission.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What type of forum was the subject of a January 2009 front page story in The Sun?
Ah, so.. a British Muslim internet forum

Question: Eritrea can be split into three ecoregions. To the east of the highlands are the hot, arid coastal plains stretching down to the southeast of the country. The cooler, more fertile highlands, reaching up to 3000m has a different habitat. Habitats here vary from the sub-tropical rainforest at Filfil Solomona to the precipitous cliffs and canyons of the southern highlands. The Afar Triangle or Danakil Depression of Eritrea is the probable location of a triple junction where three tectonic plates are pulling away from one another.The highest point of the country, Emba Soira, is located in the center of Eritrea, at 3,018 meters (9,902 ft) above sea level.
Try to answer this question if possible: How many ecoregions make up Eritrea?
Answer: three

Input: Read this: The actual substance of English law was formally "received" into the United States in several ways. First, all U.S. states except Louisiana have enacted "reception statutes" which generally state that the common law of England (particularly judge-made law) is the law of the state to the extent that it is not repugnant to domestic law or indigenous conditions. Some reception statutes impose a specific cutoff date for reception, such as the date of a colony's founding, while others are deliberately vague. Thus, contemporary U.S. courts often cite pre-Revolution cases when discussing the evolution of an ancient judge-made common law principle into its modern form, such as the heightened duty of care traditionally imposed upon common carriers.
Question: Lowered duty of care is placed on what?
