impermeability
A cell wall is a tough and flexible layer surrounding the cell membrane in plants, algae, and most prokaryotes. The cell wall shows complete permeability as it helps to transport substances in and out of the cell.
So, the correct answer is A) 'Complete permeability'.
A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is :
