Q: Muscle atrophy due to age is called what? Read this paragraph and choose the correct option from the provided answers: mitochondria, myoglobin, and capillary networks in SO fibers. Endurance athletes have a high level of SO fibers relative to the other fiber types. Resistance exercise causes hypertrophy. Power-producing muscles have a higher number of FG fibers than of slow fibers. Strenuous exercise causes muscle cell damage that requires time to heal. Some athletes use performanceenhancing substances to enhance muscle performance. Muscle atrophy due to age is called sarcopenia and occurs as muscle fibers die and are replaced by connective and adipose tissue. Choices: - nymphomania - Increased Atrophy - pepinia - sarcopenia A:
**Answer**
sarcopenia

Q: What is the process in which one cell divides to form two new cells called? Read this paragraph and choose the correct option from the provided answers: Cell division is part of the life cycle of virtually all cells. Cell division is the process in which one cell divides to form two new cells. Choices: - cell direction - cell contribution - Cell Formation - cell division A:
**Answer**
cell division

**Answer**
tubulin

Q: Tanning salons claim to use a "safe" form of what light, with a longer wavelength than that in sunlight? Read this paragraph and choose the correct option from the provided answers: 29.3 Photon Energies and the Electromagnetic Spectrum 11. Why are UV, x rays, and rays called ionizing radiation? 12. How can treating food with ionizing radiation help keep it from spoiling? UV is not very penetrating. What else could be used? 13. Some television tubes are CRTs. They use an approximately 30-kV accelerating potential to send electrons to the screen, where the electrons stimulate phosphors to emit the light that forms the pictures we watch. Would you expect x rays also to be created? 14. Tanning salons use "safe" UV with a longer wavelength than some of the UV in sunlight. This "safe" UV has enough photon energy to trigger the tanning mechanism. Is it likely to be able to cause cell damage and induce cancer with prolonged exposure? 15. Your pupils dilate when visible light intensity is reduced. Does wearing sunglasses that lack UV blockers increase or decrease the UV hazard to your eyes? Explain. One could feel heat transfer in the form of infrared radiation from a large nuclear bomb detonated in the atmosphere 75 km from you. However, none of the profusely emitted x rays or rays reaches you. Explain. Can a single microwave photon cause cell damage? Explain. In an x-ray tube, the maximum photon energy is given by. Choices: - infrared - microwave - X rays - uv (ultraviolet) A:
**Answer**
uv (ultraviolet)
