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.
4. What are the characteristics of sound waves? Some sound waves are periodic, in that the change from equilibrium (average atmospheric pressure) to maximum compression to maximum rarefaction back to equilibrium is repetitive. The 'round trip' back to the starting point just described is called a cycle.
