Question

3/5×[-3/7]-1/6×3/2+1/14×2/5​

Answer 1

t is called plasmolysis. When a plasmolysed cell is placed in a hypotonic solution, (i.e., the solution having solute concentration lower than the cell sap), the water moves into the cell because of the higher concentration of water outside the cell than in the cell. The cell then swells to become turgid.

Answer 2

Step-by-step explanation:

$(3 \div 5 \times - 3 \div 7) - (1 \div 6 \times 3 \div 2) + (1 \div 4 \times 2 \div 5) \\ - 6 \div 35 - 1 \div 4 + 1 \div 35 \\ taking \: lcm \: it \: will \: come \: 140 \\ so - 24 + 4 - 35 \div 140 \\ - 55 \div 140 \\ - 11 \div 28$
