The farmers of Punjab, Haryana and Uttar Pradesh have shifted to cultivation of HYVs of rice and wheat
which require plenty of water. The main source of irrigation in these states is tube wells that draw
groundwater. Groundwater can be maintained as long as the use of groundwater is less than the
groundwater recharge.
Secondly, the use of fertilizers and pesticides which is essential for HYV cultivation, nevertheless act

The groundwater and soil fertility which is built up over long period of time, once destroyed, it is near
impossible to restore them.​

Answer 1

Answer:

Water moves across cell membranes by diffusion, in a process known as osmosis. Osmosis refers specifically to the movement of water across a semipermeable membrane, with the solvent (water, for example) moving from an area of low solute (dissolved material) concentration to an area of high solute concentration.
