Four varieties of bacteria have been found in the bee bread of the larva: Bacillus circulans, B. coagulans, B. firmus, and B. megaterium. Only the Bacillus genus has been found in the samples taken. Together, these four species were able to hydrolyze starch, ferment glucose, convert nitrates to nitrites, and produce dihydroxyacetone from glycerol. This group of bacteria also lowers the pH of the bee bread. These functions serve not only to protect the larva from other bacteria, but they also digest complex molecules which allow the larva to easily absorb nutrients without expending a lot of energy. The bacteria, in turn, receive a supply of food which results in a mutualistic relationship.[13]
Macintosh Centris is a family of personal computers designed, manufactured and sold by Apple Computer, Inc. in 1992 and 1993. They were introduced as a replacement for the six-year-old Macintosh II family of computers; the name was chosen to indicate that the consumer was selecting a Macintosh in the center of Apple's product line. Centris machines were the first to offer Motorola 68040 CPUs at a price point around $2,500 USD, making them significantly less expensive (albeit slower) than Quadra computers, but also offering higher performance than the Macintosh LC computers of the time.

Le patrimoine architectural de Québec comprend l'ensemble des bâtiments de l'Assemblée nationale qui ont été érigés sur la colline Parlementaire à partir de 1877. On y retrouve deux styles architecturaux, soit le style Second Empire pour l'Hôtel du Parlement et l'architecture Beaux-Arts pour les autres édifices. La Citadelle de Québec, construite entre 1820 et 1831, le Château Frontenac, bâti entre 1892 et 1893, et la Terrasse Dufferin font également partie du site patrimonial du Vieux-Québec.
