Ques & Ans: Halophiles are organisms that thrive in high salt concentrations. They are a type of extremophile organisms. The name comes from the Greek word for "salt-loving". While most halophiles are classified into the Archaea domain, there are also bacterial halophiles and some eukaryota, such as the alga Dunaliella salina or fungus Wallemia ichthyophaga. Some well-known species give off a red color from carotenoid compounds, notably bacteriorhodopsin. Halophiles can be found anywhere with a concentration of salt five times greater than the salt concentration of the ocean, such as the Great Salt Lake in Utah, Owens Lake in California, the Dead Sea, and in evaporation ponds.

Halophiles require what in high concentrations for growth?
salt
Stream of consciousness: To answer the question, consider the following: Halophiles are organisms that thrive in high salt concentrations.

Ques & Ans: Context: The superior vena cava (SVC) is the superior of the two venae cavae, the great venous trunks that return deoxygenated blood from the systemic circulation to the right atrium of the heart. It is a large-diameter (24 mm), yet short, vein that receives venous return from the upper half of the body, above the diaphragm. (Venous return from the lower half, below the diaphragm, flows through the inferior vena cava.) The SVC is located in the anterior right superior mediastinum. It is the typical site of central venous access (CVA) via a central venous catheter or a peripherally inserted central catheter. Mentions of "the cava" without further specification usually refer to the SVC.

Question: the superior vena cava returns blood to the heart from the?
the systemic circulation
Stream of consciousness: To answer this question, we should know that: The superior vena cava (SVC) is the superior of the two venae cavae, the great venous trunks that return deoxygenated blood from the systemic circulation to the right atrium of the heart.

Ques & Ans: Passage: After the outbreak of World War I the Defence of the Realm Act was passed by Parliament in 1914. One section of the Act concerned the hours pubs could sell alcohol, as it was believed that alcohol consumption would interfere with the war effort. It restricted opening hours for licensed premises to luncheon (12: 00 to 14: 40) and supper (18: 30 to 22: 30). In the late 1980s the licensing laws in England and Wales became less restricted and allowed pubs to allow the consumption of alcohol on the premises from 11: 00 until 23: 00, although nightclubs were allowed to stay open much later. Significantly revised rules were introduced in November 2005, when hour limits were scrapped, and pubs were allowed to apply for licences as permissive as "24 hours a day". In practice, most pubs chose not to apply for licences past midnight.

Question: Based on this passage, when did pubs stop closing in the afternoon?
the late 1980s
Stream of consciousness: This is the relevant information: In the late 1980s the licensing laws in England and Wales became less restricted and allowed pubs to allow the consumption of alcohol on the premises from 11: 00 until 23: 00, although nightclubs were allowed to stay open much later.

Ques & Ans: In Unix-like operating systems, chmod is the command and system call which may change the access permissions to file system objects (files and directories). It may also alter special mode flags. The request is filtered by the umask. The name is an abbreviation of change mode.

The important part for answering this question is: In Unix-like operating systems, chmod is the command and system call which may change the access permissions to file system objects (files and directories).
