In general, a statement from the National Health and Nutrition Examination Survey conducted from 2001-2004 found the average American consumes about 355 calories of added sugar a day, or the equivalent of 22.2 teaspoons.
Sound waves stimulation could increase the plant plasma-membrane H + -ATPase activity, the contents of soluble sugar, soluble protein, and amylase activity of callus. Moreover, sound waves could increase the content of RNA and the level of transcription.
Speed of sound depends on the medium. Sound waves can travel through solids, liquids, and gases. Because waves consist of particle vibrations, the speed of a wave depends on how quickly one particle can transfer its motion to another particle. The speed of sound also depends on the temperature of the medium. As temperature rises, the particles of a gas collide more frequently. Define the Doppler Effect.
