Input: Read this: Madonna's use of sexual imagery has benefited her career and catalyzed public discourse on sexuality and feminism. As Roger Chapman documents in Culture Wars: An Encyclopedia of Issues, Viewpoints, and Voices, Volume 1 (2010), she has drawn frequent condemnation from religious organizations, social conservatives and parental watchdog groups for her use of explicit, sexual imagery and lyrics, religious symbolism, and otherwise "irreverent" behavior in her live performances. The Times wrote that she had "started a revolution amongst women in music ... Her attitudes and opinions on sex, nudity, style and sexuality forced the public to sit up and take notice." Professor John Fiske noted that the sense of empowerment that Madonna offers is inextricably connected with the pleasure of exerting some control over the meanings of self, of sexuality, and of one's social relations. In Doing Gender in Media, Art and Culture (2009), the authors noted that Madonna, as a female celebrity, performer, and pop icon, is able to unsettle standing feminist reflections and debates. According to lesbian feminist Sheila Jeffreys, Madonna represents woman's occupancy of what Monique Wittig calls the category of sex, as powerful, and appears to gleefully embrace the performance of the sexual corvee allotted to women. Professor Sut Jhally has referred to Madonna as "an almost sacred feminist icon."

Input: Read this: Both the number of base pairs and the number of genes vary widely from one species to another, and there is only a rough correlation between the two (an observation known as the C-value paradox). At present, the highest known number of genes is around 60,000, for the protozoan causing trichomoniasis (see List of sequenced eukaryotic genomes), almost three times as many as in the human genome.
