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).
A) Mitochondria - because they are double membraned and the inner one is highly folded into 'cristae'
I'm not sure if there are answer choices, but water is an excellent solvent, taking along valuable nutrients with it when it travels.
