Q. If a healthy freshwater fish is placed in salt water, what will be the expected consequence

(A) The fish becomes bloated & dies
(B) There is no observable effect on the fish provided there is sufficient food
(C) The fish suffers from fungal or bacterial disease & dies
(D) The fish becomes dehydrated & dies

Correct Answer - Option(D)

Explanation by: Ruchi Sharma

The fish becomes dehydrated & dies.When freshwater fish is placed in salt water, the water molecules contained in the fish's body would pass through the cell membranes of the fish, causing the fish to lose water by diffusion. This sudden change in the molecular makeup of the fish wouldcause the fish to die.
