C. Questions 1. 0.9% NaCl (saline) and 5% glucose solutions are considered isotonic to red blood cells. If a cell is placed in a hypotonic solution hemolysis (bursting) takes place; if a cell is placed in a hypertonic solution crenation (shrinking) takes place. State whether each of the following solutions is hypotonic, hypertonic, or isotonic to red blood cells and whether crenation, hemolysis, or no change will take place. Solution | Hypotonic, Hypertonic, or Isotonic | Crenation, Hemolysis, or No Change ---|---|--- a. 3% NaCl | | b. 5% glucose | | c. Pure H2O | |

1. Which of the following solutions contains the highest concentration of water molecules? salt water distilled water fresh water none of the choices are correct 2. Rain water moves into a tree root by osmosis. Which of the following describes the rain water relative to the tree root cells? hypotonic hypertonic isotonic rain water has a higher solute concentration than the cytoplasm of the tree root cells 3. Potato cells that are placed in salt water for 24 hours lose weight. What is the correct term to identify the potato cell cytoplasm relative to the salt water surrounding the potato? isotonic hypotonic hypertonic all of the choices are correct 4. Which of the following would provide evidence that water is diffusing into cells? the cells gain mass the cells feel firmer the cells get bigger all of the choices are correct
