A Fourier analysis is a technique that is able to determine both the amplitude spectrum and the phase <span>spectrum of any signal</span>. This analysis is based on the finding that all sound waves can be derived by adding sinusoids together (so long as the sinusoids are of the appropriate frequencies, amplitudes, and phases).
Probably nothing. There are a lot of vegetarians in California and Australia and Oceania and Asia (mostly Japan and India).
Variation means difference in genetic makeup between individuals within a specie.
An example of photosynthesis is how plants convert sugar and energy from water, air and sunlight into energy to grow. The biological synthesis of chemical compounds in the presence of light
