Question

How does water move?

Select one:

a. Water follows salt

b. Water moves down its concentration gradient

c. Water moves across permeable membranes

d. Water follows solutes

e. All of the above

Answer 1

ANS - All of the above.

EXPLANATION--> OSMOSIS is the process in which water moves from higher concentrartion region to lower concentration region in through the semipermable membrane in order equalise the water concentraion.

• During this process water moves from the higher to lower concentration, thus water diffused down to its concentration gradient, while crossing the semi permeable membrane where it is less concentrated.
• Sodium passes from the filtrate, into and through the cells of the tubules and ducts , in the ECF and then towards the capillaries, water follows the sodium because of the osmosis.
