Science and Technology Fundamentals

H and N stand for Haemagglutinin and Neuraminidase, which are surface proteins on influenza viruses. H5N1 causes avian flu in birds, not normal flu. The hypothalamus/neurotransmitter options are biologically incorrect.

Bluetooth technology was first developed by Ericsson Mobile Communications in 1994. The name comes from the 10th century Danish King Harald Blatand (Bluetooth), who unified Denmark and Norway. Option A is correct.

Wireless technology indeed encompasses a broad spectrum of applications including traditional radio and TV broadcasting, mobile phones, Bluetooth, and wireless LAN networks. This comprehensive range makes 'True' the correct answer.

In f-stop notation, a smaller denominator number means a larger aperture and more light. Among these fractions, 1/8 is the largest value, allowing the most light. 1/32 is the smallest (least light), with 1/16 and 1/12 being intermediate values. This counterintuitive concept often confuses photography students.

Shutter speed is expressed as fractions of a second. A larger denominator means a shorter exposure time, making the shutter faster. 1/250th second exposes the sensor for less time than 1/125th, 1/25th, or 1/8th second, making it the fastest shutter speed among the options.

NASA developed digital imaging technology in the 1960s to process and enhance images from space missions. The technology was needed to improve photographs taken during lunar and planetary explorations. NASA's work laid the foundation for modern digital imaging used in cameras and medical imaging today.

In additive color theory for light, red, green, and blue are the three primary colors. These colors can be combined in various intensities to produce all other colors visible to the human eye. This RGB color model is used in television screens, computer monitors, and other digital display technologies.

Ford Motor Company, founded in 1903 by Henry Ford, revolutionized automotive manufacturing with the moving assembly line introduced in 1913. This innovation dramatically reduced production time and costs, making cars affordable for the masses. Toyota (1937), General Motors (1908 but didn't pioneer the assembly line), and DaimlerChrysler (formed in 1998) came later or had different innovations.

Sony Corporation was founded in 1946 by Masaru Ibuka and Akio Morita as Tokyo Tsushin Kogyo (Tokyo Telecommunications Engineering Corporation) with headquarters in Tokyo, Japan. Sony revolutionized global consumer electronics through innovations like the transistor radio, Walkman, and Trinitron TV technology.

Apple was founded in 1976 by Steve Jobs, Steve Wozniak, and Ronald Wayne, and revolutionized personal computing by making it accessible to mass consumers through user-friendly design. IBM was founded much earlier (1911), Sun Microsystems in 1982, and Compaq in 1982.
