A drone is a male honey bee that is the product of an unfertilized egg. Unlike the female worker bee, drones do not have stingers and do not participate in nectar and pollen gathering. A drone's primary role is to mate with a fertile queen.
Drones carry only one type of allele at each chromosomal position, because they are haploid (containing only one set of chromosomes from the mother). During the development of eggs within a queen, a diploid cell with 32 chromosomes divides to generate haploid cells called gametes with 16 chromosomes. The result is a haploid egg, with chromosomes having a new combination of alleles at the various loci. This process is also called arrhenotokous parthenogenesis or simply arrhenotoky.
Because the male bee technically has only a mother, and no father, its genealogical tree is rather interesting. In the first generation there is one member (the male). One generation back there is also one member (the mother). Two generations back there are two members (the mother and father of the mother). Three generations back there are three members. Four back there are five members. That is, the numbers in each generation going back are 1, 1, 2, 3, 5, 8, ... —

Season one of Smallville, an American television series developed by Alfred Gough and Miles Millar, began airing on October 16, 2001, on The WB television network. The series recounts the early adventures of Kryptonian Clark Kent as he adjusts to his developing superpowers in the fictional town of Smallville, Kansas, during the years before he becomes Superman. The first season comprises 21 episodes and concluded its initial airing on May 21, 2002. Regular cast members during season one include Tom Welling, Michael Rosenbaum, Kristin Kreuk, Annette O'Toole, John Schneider, Sam Jones III, Allison Mack, and Eric Johnson.
The season's stories focus on Martha and Jonathan Kent's (O'Toole and Schneider) attempts to help their adopted son Clark (Welling) cope with his alien origin and control his developing superhuman abilities. Clark must deal with the meteor-infected individuals that begin appearing in Smallville, his love for Lana Lang (Kreuk), and not being able to tell his two best friends, Pete Ross (Jones III) and Chloe Sullivan (Mack), about his abilities or his origins. Clark also befriends Lex Luthor (Rosenbaum) after saving Lex's life. The season also follows Lex, as he tries to assert his independence from his father, Lionel Luthor (John Glover).
Drone is a 2014 English-language documentary film directed by Norwegian director Tonje Hessen Schei. The film explores the use of drones in warfare. Drone aired on the TV network Arte on April 15, 2014. The documentary screened at several film festivals throughout 2014, winning several awards. Drone was released in Norway on February 27, 2015.
Variety reported, "'Drone' depicts the recruitment of young pilots at gaming conventions, explores the changing perceptions of what 'going to war' means, as well as the moral stance of engineers behind the technology. The docu also investigates the ways in which world leaders engage in wars, as well as look at the struggle of anti-war and civil rights activists."
Drone was produced by Lars Løge at Flimmer Film and directed by Tonje Hessen Schei. The film received financial support from backers in Norway and from around the world.
The sales outfit LevelK acquired Drone at the Nordic Film Market at the Gothenburg Film Festival in January 2014. A 58-minute cut of Drone premiered on the TV network Arte on April 15, 2014. A 79-minute cut was edited for subsequent screenings. In October 2014, Drone screened at the Bergen International Film Festival and won Best Norwegian Documentary and the Checkpoint Human Rights awards. In January 2015, it screened at the Tromsø International Film Festival and won the Norwegian Peace Film Award. In the following February, it screened at the Berlin International Film Festival and won the Cinema for Peace award. In the same month, LevelK sold distribution rights to Drone to several major territories.
Bees are flying insects closely related to wasps and ants, known for their role in pollination and, in the case of the best-known bee species, the European honey bee, for producing honey and beeswax. Bees are a monophyletic lineage within the superfamily Apoidea, presently considered as a clade Anthophila. There are nearly 20,000 known species of bees in seven to nine recognized families, though many are undescribed and the actual number is probably higher. They are found on every continent except Antarctica, in every habitat on the planet that contains insect-pollinated flowering plants.
Some species including honey bees, bumblebees, and stingless bees live socially in colonies. Bees are adapted for feeding on nectar and pollen, the former primarily as an energy source and the latter primarily for protein and other nutrients. Most pollen is used as food for larvae. Bee pollination is important both ecologically and commercially; the decline in wild bees has increased the value of pollination by commercially managed hives of honey bees.
Bee is the name of the following newspapers:
Communal work is when a gathering takes place to accomplish a task or to hold a competition. A number of cultures have such gatherings, often for the purpose of holding a competition, as in a spelling bee, or for providing manual labour, as in a barn raising.
Especially in the past, the tasks were often major jobs, such as clearing a field of timber or raising a barn, that would be difficult to carry out alone. It was often both a social and utilitarian event. Jobs like corn husking or sewing, could be done as a group to allow socializing during an otherwise tedious chore. Such gatherings often included refreshments and entertainment provided by the group. Different words have been used to describe such gatherings.
This use of the word bee is common in literature describing colonial North America. It was, and continues to be, commonly used in Australia also, most often as "working bee".
