Answer 1

Answer:

because of exosmosis and endosmosis

Answer 2

Answer:

i) Because Both C And D's Concentration Is Less Due To Salt And Sugar, So The water Comes Out Of The Cell Due To Exosmosis.

iii) Because These Is No Concentration Outside The Cell, (And Osmosis Occurs When Outside Is Less Concentration Not Zero Concentration) That's Why Water Does Not Came Out.
