Here is a question about this article: Persistent infections occur because the body is unable to clear the organism after the initial infection. Persistent infections are characterized by the continual presence of the infectious organism, often as latent infection with occasional recurrent relapses of active infection. There are some viruses that can maintain a persistent infection by infecting different cells of the body. Some viruses once acquired never leave the body. A typical example is the herpes virus, which tends to hide in nerves and become reactivated when specific circumstances arise.
What is the answer to this question: How can some viruses main a persistent infection?

So... by infecting different cells of the body


Here is a question about this article: The Arabs undertook large-scale efforts at translation. Having conquered the Greek world, they made Arabic versions of its philosophical and scientific works. During the Middle Ages, translations of some of these Arabic versions were made into Latin, chiefly at Córdoba in Spain. King Alfonso X el Sabio (Alphonse the Wise) of Castille in the 13th century promoted this effort by founding a Schola Traductorum (School of Translation) in Toledo. There Arabic texts, Hebrew texts, and Latin texts were translated into the other tongues by Muslim, Jewish and Christian scholars, who also argued the merits of their respective religions. Latin translations of Greek and original Arab works of scholarship and science helped advance European Scholasticism, and thus European science and culture.
What is the answer to this question: What is Schola Traductorum in English?

So...
