s=ut+ 1/2 at2
=19.6×5−1/2 ×9.8×52
=−24.5 m
Hence, height of tower =24.5m
v = u + at
=19.6−9.8×5=−29.4 m/s

Salt can be recovered from its solution by crystallization.
Crystallization is the process of formation of solid crystals precipitation from a solution. It is Solid- liquid separation.
By using ' crystallization technique, ' salt can be recollected from its solution. This technique is better than ' evaporation ' because it removes dissolved impurities which are present in the solution.
But in the evaporation process we cannot remove the dissolved impurities present in the solution.

-The movement of water across a semi-permeable membrane is affected by the amount of substance dissolved in it. As water moves from higher concentration to lower concentration.
-Membranes are made of organic molecules like proteins and lipids. The ratio of protein and lipids vary considerably in different cell types. In human beings, the membrane of the erythrocyte has approximately 52 per cent protein and 40 per cent lipids.
-Molecules soluble in organic solvents can easily pass through the membrane as the membrane is lipophilic.
-Cell walls of fungi contain chitin sugar.
So, the correct answer is 'Plasma membrane contain chitin sugar in plants'.
