Detailed explanation-1: -Answer. Answer: An egg with a dissolved shell is placed in pure water for 48 hours. Water will move in and out of the cell equally, and the cell with neither shrink nor swell.
Detailed explanation-2: -When this is semipermeable egg is placed in a saline solution (hypertonic solution), exosmosis occurs and the egg shrinks due to loss of water to the surrounding environment. If the water concentration inside is higher than the surrounding environment, the medium is said to be hypertonic solution.
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: -Key Idea: Salt pulls water out of cells killing them. The eggplant will get very wet.
Detailed explanation-5: -Giving large amounts of pure water directly into a vein would cause your blood cells to become hypotonic, possibly leading to death.
