Alpha (ethology)

In studies of social animals, the highest ranking individual is sometimes designated as the alpha. Males, females, or both, can be alphas, depending on the species. Where one male and one female fulfill this role together, they are sometimes referred to as the alpha pair. Other animals in the same social group may exhibit deference or other species-specific subordinate behaviours towards the alpha or alphas.

Alpha animals usually gain preferential access to food and other desirable items or activities, though the extent of this varies widely between species. Male or female alphas may gain preferential access to sex or mates; in some species, only alphas or an alpha pair reproduce.

Alphas may achieve their status by superior physical strength and aggression, or through social efforts and building alliances within the group.

The individual with alpha status sometimes changes, often through a fight between the dominant and a subordinate animal. Such fights may or may not be to the death.

Selena albums discography

American singer Selena has released five studio albums, three live albums, one soundtrack and twenty-one compilation albums. Credited for elevating a music genre into the mainstream market, Selena remains the best-selling Tejano recording artist whose posthumous releases continue to outsell those of living musicians. As of 2015, the singer has sold 60 million copies worldwide, and was named the "Top Latin Artist of the '90s" and "Best-selling Latin Artist of the Decade" by Billboard magazine. In 1995, Selena was inducted into the Billboard Latin Music Hall of Fame, the Hard Rock Cafe's Hall of Fame, the South Texas Music Hall of Fame, and the Tejano Music Hall of Fame in 2001.

Selena's career began as lead vocalist of Los Dinos in 1980. She signed with EMI Latin nine years later as a solo artist though her band continued to tour with her. She released her self-titled debut album that same year, which peaked at number seven on the U.S. Billboard Regional Mexican Albums chart. With Selena, the singer outsold other female Tejano artists. She released her second album Ven Conmigo in October 1990; it peaked at number three on the Regional Mexican Albums chart. Ven Conmigo was later certified gold by the Recording Industry Association of America (RIAA) for shipments of 50,000 units, the first recording by a female Tejano artist to do so. As of 2010, Ven Conmigo had sold 500,000 copies in the United States. According to music critics, her next recording Entre a Mi Mundo (1992), was the "breakthrough album" of her musical career. The album and its lead single, "Como la Flor", helped launch the singer's career in Mexico.Entre a Mi Mundo peaked at number one on the Regional Mexican Albums chart for eight consecutive months; and was certified 6× platinum by the RIAA, signifying shipments of 600,000 units. Entre a Mi Mundo became the first Tejano recording by a female artist to sell over 300,000 copies.

Limited Edition (Magic: The Gathering)

Magic: The Gathering Limited Edition is the first Magic: The Gathering card set. It premiered in a limited release at Origins Game Fair in 1993, with a general release that August. The initial print run of 2.6 million cards sold out quickly, and a new printing run was released in October 1993. These two runs are known as Limited Edition Alpha and Limited Edition Beta, or just Alpha and Beta for short. Although Alpha and Beta are referred to as different sets by some, officially they are the same set; Wizards of the Coast had expected that people wouldn't necessarily be able to tell the two press runs apart. Beta fixed a number of misprints and errors on cards. The printer accidentally used different corner rounding dies for the second run, resulting in Alpha cards being noticeably distinct in shape and appearance from Beta cards and all subsequent cards. The Beta printing also included a revised rulebook with a number of clarifications, although creator Richard Garfield's short fiction "Worzel's Tale" was removed to make room. The print run of Beta is given as 7.3 million or 7.8 million depending on the source. Despite the set's print run being about three times as big as Alpha's, Beta sold out as quickly as its predecessor.

Biology

Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, evolution, distribution, and taxonomy. Modern biology is a vast and eclectic field, composed of many branches and subdisciplines. However, despite the broad scope of biology, there are certain general and unifying concepts within it that govern all study and research, consolidating it into single, coherent fields. In general, biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the synthesis and creation of new species. It is also understood today that all organisms survive by consuming and transforming energy and by regulating their internal environment to maintain a stable and vital condition.

Subdisciplines of biology are defined by the scale at which organisms are studied, the kinds of organisms studied, and the methods used to study them: biochemistry examines the rudimentary chemistry of life; molecular biology studies the complex interactions among biological molecules; botany studies the biology of plants; cellular biology examines the basic building-block of all life, the cell; physiology examines the physical and chemical functions of tissues, organs, and organ systems of an organism; evolutionary biology examines the processes that produced the diversity of life; and ecology examines how organisms interact in their environment.

Biology (journal)

Biology is a quarterly, peer-reviewed, open access, scientific journal covering research on all aspects of biology. It was established in 2012 and is published by MDPI. The editor-in-chief is Chris O'Callaghan (University of Oxford). The journal publishes reviews, research papers, and communications.

Subject Areas

This journal covers all topics related to biology. More detail about the journal and its scope is available in the first editorial. Research fields of interest include, but are not limited to:

Biology 101

"Biology 101" is the first episode of the third season of Community. The episode originally aired on September 22, 2011 on NBC. The episode picks up where the second season left off, with Pierce out of the group. The study group resumes class at Greendale and decides to enroll in Biology.

The episode was written by Neil Goldman and Garrett Donovan and directed by Anthony Russo.

Plot

The study group decides to take a Biology class together, but Pierce soon faces problems when only six seats are available in the class. Jeff quickly makes enemies with their professor (Michael K. Williams) and is removed from the class, leaving an open slot for Pierce in both the class and their study group. Jeff's plans to reveal Pierce's relationship to the new professor backfires. Dean Pelton unwisely stokes a rivalry with Vice Dean Laybourne (John Goodman), the dean of the school's lucrative Air Conditioning Repair Annex. Abed becomes despondent when Cougar Town goes into hiatus and the group tries to cheer him up by introducing him to Cougarton Abbey, a British show that Cougar Town was based on. Unfortunately, that show was cancelled after six episodes, ending with the main characters committing mass suicide.
