Compare a newtonian fluid to a non-newtonian fluid.. how are they different?

Newtonian fluids have a constant viscosity that doesn’t change, no matter the pressure being applied to the fluid. This also means they don’t compress.

Non-Newtonian fluids are just the opposite — if enough force is applied to these fluids, their viscosity will change. These fluids are broken up into two categories — dilatants, which get thicker when force is applied, and pseudoplastics, which get thinner under the same circumstances.

These can be further broken down into rheopectic and thixotropic categories. Rheopectics work like dilatants in that they get thicker when force is applied. Thixotropic materials get thinner, like pseudoplastics do. The difference here is that the latter two categories are time dependant. The viscosity doesn’t change immediately but changes slowly over time as more and more force is applied.

Newtonian vs. Non-Newtonian Liquids

The correct answer is option A. It can stretch more.

Explanation:

Epithelial tissues are made the covering of the body and provide the first line of protection from biological, physical and chemical infections or injuries. The epithelium cells play the role of gatekeepers by controlling allowing selective transfer of materials across a physical barrier.

Transitional cells are one of the epithelial cells that have all basic similarities except they can stretch but epithelial cells can not. Transitional cells form the cell of the wall of the uterus and bladder that provide stretching to the organs during pregnancy and urine storage respectively.

Thus, the correct answer is option A. It can stretch more.
