please answer this question with clear steps

There are many fluids that exhibit non-Newtonian behavior. For a given fluid, the distinction between Newtonian and non-Newtonian behavior is usually based on measurements of shear stress and rate of shearing strain. Assume that the viscosity of blood is to be determined by measurements of shear stress, T, and rate of shearing strain, du/dy, obtained from a small blood sample tested in a suitable viscometer. (a) Based on the data given below, determine if the blood is a Newtonian or non-Newtonian fluid. (b) Explain how you arrived at your answer. T.
