The 1998 edition of Guinness Book of World Records stated: "No female artist has sold more records than Madonna around the world". In 1999 Madonna signed to play a violin teacher in the film Music of the Heart but left the project, citing "creative differences" with director Wes Craven. She recorded the single "Beautiful Stranger" for the 1999 film Austin Powers: The Spy Who Shagged Me. It reached number 19 on the Hot 100 solely on radio airplay. Madonna won a Grammy Award for "Best Song Written for a Motion Picture, Television or Other Visual Media".
Which edition of the Guinness Book of World Record states that no female artist sold more records than Madonna?
****
The answer: 1998

Recent years have seen increasing applications of genetic and genomic techniques to the study of the brain and a focus on the roles of neurotrophic factors and physical activity in neuroplasticity. The most common subjects are mice, because of the availability of technical tools. It is now possible with relative ease to "knock out" or mutate a wide variety of genes, and then examine the effects on brain function. More sophisticated approaches are also being used: for example, using Cre-Lox recombination it is possible to activate or deactivate genes in specific parts of the brain, at specific times.
What is the most common test subjects for studying of the brain?
****
The answer: mice

Wright himself believed that values >0.25 represent very great genetic variation and that an FST of 0.150.25 represented great variation. However, about 5% of human variation occurs between populations within continents, therefore FST values between continental groups of humans (or races) of as low as 0.1 (or possibly lower) have been found in some studies, suggesting more moderate levels of genetic variation. Graves (1996) has countered that FST should not be used as a marker of subspecies status, as the statistic is used to measure the degree of differentiation between populations, although see also Wright (1978).
FST values greater than .25 represent very great what?
****
The answer: genetic variation

USB was designed to standardize the connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters) to personal computers, both to communicate and to supply electric power. It has become commonplace on other devices, such as smartphones, PDAs and video game consoles. USB has effectively replaced a variety of earlier interfaces, such as serial and parallel ports, as well as separate power chargers for portable devices.
What was designed to standardize the connection of computer peripherals?
****
The answer:
USB
