Answers
Answer:
1))Reverse osmosis::The phenomenon of reversal of the direction of osmosis by the application of a pressure larger than the osmotic pressure on the solution side is known as reverse osmosis..
2))diffusion and graham law::Graham's law states that the rate of diffusion or of effusion of a gas is inversely proportional to the square root of its molecular weight. ... Therefore, the rates of diffusion of different gases are inversely proportional to the square roots of their mass densities.
3))characters of arthropoda::

They have jointed appendages.
Their body is segmented.
They are bilaterally symmetrical.
They possess an open circulatory system
4))mollusca ::
