QUES: Serological methods are highly sensitive, specific and often extremely rapid tests used to identify microorganisms. These tests are based upon the ability of an antibody to bind specifically to an antigen. The antigen, usually a protein or carbohydrate made by an infectious agent, is bound by the antibody. This binding then sets off a chain of events that can be visibly obvious in various ways, dependent upon the test. For example, "Strep throat" is often diagnosed within minutes, and is based on the appearance of antigens made by the causative agent, S. pyogenes, that is retrieved from a patients throat with a cotton swab. Serological tests, if available, are usually the preferred route of identification, however the tests are costly to develop and the reagents used in the test often require refrigeration. Some serological methods are extremely costly, although when commonly used, such as with the "strep test", they can be inexpensive.

What methods are highly sensitive, specifc and rapid tests used to identify microorganisms?
What is the answer?
ANS: Serological
QUES: In 1961, Nasser sought to firmly establish Egypt as the leader of the Arab world and to promote a second revolution in Egypt with the purpose of merging Islamic and socialist thinking. To achieve this, he initiated several reforms to modernize al-Azhar, which serves as the de facto leading authority in Sunni Islam, and to ensure its prominence over the Muslim Brotherhood and the more conservative Wahhabism promoted by Saudi Arabia. Nasser had used al-Azhar's most willing ulema (scholars) as a counterweight to the Brotherhood's Islamic influence, starting in 1953.

What religious group did Nasser endeavor to reform?
What is the answer?
ANS: al-Azhar
QUES: The UCS-2 and UTF-16 encodings specify the Unicode Byte Order Mark (BOM) for use at the beginnings of text files, which may be used for byte ordering detection (or byte endianness detection). The BOM, code point U+FEFF has the important property of unambiguity on byte reorder, regardless of the Unicode encoding used; U+FFFE (the result of byte-swapping U+FEFF) does not equate to a legal character, and U+FEFF in other places, other than the beginning of text, conveys the zero-width non-break space (a character with no appearance and no effect other than preventing the formation of ligatures).

What is the code point for BOM?
