Article: Some species use vibrations for communicating within members of the same species, such as to attract mates as in the songs of the shield bug Nezara viridula. Vibrations can also be used to communicate between entirely different species; lycaenid (gossamer-winged butterfly) caterpillars which are myrmecophilous (living in a mutualistic association with ants) communicate with ants in this way. The Madagascar hissing cockroach has the ability to press air through its spiracles to make a hissing noise as a sign of aggression; the Death's-head Hawkmoth makes a squeaking noise by forcing air out of their pharynx when agitated, which may also reduce aggressive worker honey bee behavior when the two are in close proximity.

Question: Vibrations are used to communicate with members of the same species, and what other species?
Ans: different species

Article: The bacterial cell is surrounded by a cell membrane (also known as a lipid, cytoplasmic or plasma membrane). This membrane encloses the contents of the cell and acts as a barrier to hold nutrients, proteins and other essential components of the cytoplasm within the cell. As they are prokaryotes, bacteria do not usually have membrane-bound organelles in their cytoplasm, and thus contain few large intracellular structures. They lack a true nucleus, mitochondria, chloroplasts and the other organelles present in eukaryotic cells. Bacteria were once seen as simple bags of cytoplasm, but structures such as the prokaryotic cytoskeleton and the localization of proteins to specific locations within the cytoplasm that give bacteria some complexity have been discovered. These subcellular levels of organization have been called "bacterial hyperstructures".

Question: Do bacteria have membrabe-bound organelles in their cytoplasm?
Ans: do not

Article: Canada's Armed forces operate out of 27 Canadian Forces bases (CFB) across the country, including NDHQ. This number has been gradually reduced since the 1970s with bases either being closed or merged. Both officers and non-commissioned members receive their basic training at the Canadian Forces Leadership and Recruit School in Saint-Jean-sur-Richelieu. Officers will generally either directly enter the Canadian Armed Forces with a degree from a civilian university, or receive their commission upon graduation from the Royal Military College of Canada. Specific element and trade training is conducted at a variety of institutions throughout Canada, and to a lesser extent, the world.

Question: Where do Canadian Forces members go for training?
Ans: Saint-Jean-sur-Richelieu

Article: On 25 January 1952, a confrontation between British forces and police at Ismailia resulted in the deaths of 40 Egyptian policemen, provoking riots in Cairo the next day which left 76 people dead. Afterwards, Nasser published a simple six-point program in Rose al-Yusuf to dismantle feudalism and British influence in Egypt. In May, Nasser received word that Farouk knew the names of the Free Officers and intended to arrest them; he immediately entrusted Free Officer Zakaria Mohieddin with the task of planning the government takeover by army units loyal to the association.

Question: In what year did riots cause the political situation in Egypt to rapidly deteriorate?
Ans:
1952
