Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A person’s tongue cells after finishing eating a salty french fry would ____
A
get smaller
B
get bigger
C
remain the same
Explanation: 

Detailed explanation-1: -c. salt moves out of the cell causing them to shrink.

Detailed explanation-2: -A cell place in salty solution would loose water as water will move from cell to surrounding hypertonic medium by the process of osmosis causing the cell to shrivel up.

Detailed explanation-3: -If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

Detailed explanation-4: -What happens to the cells in your mouth as they react to the ELEVATED salt environment? salt moves into the cell causing them to burst.

Detailed explanation-5: -Phagocytosis. Phagocytosis (literally, “cell eating”) is a form of endocytosis in which large particles, such as cells or cellular debris, are transported into the cell.
