QUES: Long distance migrants are believed to disperse as young birds and form attachments to potential breeding sites and to favourite wintering sites. Once the site attachment is made they show high site-fidelity, visiting the same wintering sites year after year.
What do young birds form attachments to?

ANS: potential breeding sites

QUES: In 1948, the point-contact transistor was independently invented by German physicists Herbert Matare and Heinrich Welker while working at the Compagnie des Freins et Signaux, a Westinghouse subsidiary located in Paris. Matare had previous experience in developing crystal rectifiers from silicon and germanium in the German radar effort during World War II. Using this knowledge, he began researching the phenomenon of "interference" in 1947. By June 1948, witnessing currents flowing through point-contacts, Matare produced consistent results using samples of germanium produced by Welker, similar to what Bardeen and Brattain had accomplished earlier in December 1947. Realizing that Bell Labs' scientists had already invented the transistor before them, the company rushed to get its "transistron" into production for amplified use in France's telephone network.
Who invented the point-contact transistor?

ANS: Herbert Matare and Heinrich Welker

QUES: In Iberia, the Christian states, which had been confined to the north-western part of the peninsula, began to push back against the Islamic states in the south, a period known as the Reconquista. By about 1150, the Christian north had coalesced into the five major kingdoms of Leon, Castile, Aragon, Navarre, and Portugal. Southern Iberia remained under control of Islamic states, initially under the Caliphate of Cordoba, which broke up in 1031 into a shifting number of petty states known as taifas, who fought with the Christians until the Almohad Caliphate re-established centralised rule over Southern Iberia in the 1170s. Christian forces advanced again in the early 13th century, culminating in the capture of Seville in 1248.
How many major Christian kingdoms existed in Iberia around 1150?

ANS:
five
