Detailed explanation-1: -Hypotonic solution with 0.5 percent NaCl causes RBC to expand and rupture owing to the difference in osmotic pressure. The concentration of solutes in a hypotonic solution is lower than in another solution.
Detailed explanation-2: -1) 0.5% NaCl then for RBC this solution act as hypotonic solution and the RBC swells up by movement of water inside it. 2) 1%solution then for RBC this solution act as hypertonic solution and the RBC shrink by the movement of water outside it.
Detailed explanation-3: -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-4: -A solution containing 0.5% salt is hypotonic with respect to the cell.
