The bone markings of a chicken wing include the following: Head, Tubercle, Humerus, Tuberosity, Ulna, Radius, Shaft, Carpals, Condyle, Metacarpals and Phalanges. Somehow, the chicken wing and the human arm have similarities in the bone parts. Hope this is the answer that you are looking for.
Scientific investigations that involve some kind of testing will make use of observations. generally speaking making observations is the first step of the scientific method.
Equilibrium.
diffusion occurs due to differences in concentration of substances in different regions. then substances will naturally spread out (due to innate Brownian kinetic energy). the spreading I. e. diffusion will stop until equilibrium is achieved.
note: those substance particles are still moving due to the innate Brownian kinetic energies!
