Saline is a solution that contains a certain amount of nacl and is designed to have the same osmotic pressure as normal blood cells. doctors often give saline to patients who have lost blood. which of the following explains why glucose of the same molality cannot attain the same effect as saline? each formula unit of nacl will give two particles because of ionization, but each molecule of glucose dissolves to give only one particle. osmotic pressure for glucose will be lower than is required. glucose would not maintain osmotic pressure because on dissociation it forms two particles per formula unit, but nacl would give only one particle per formula unit. osmotic pressure is higher when the number of particles decreases. osmotic pressure increases with the decrease in the number of particles of solute in the solution. nacl provides fewer particles per formula unit than glucose does. sodium and chloride ions can pass freely through the membranes of red blood cells, but glucose molecules cannot pass through the membranes.

Air pressure is measured in pascals. for a professional american football game, the ball should be inflated to about 90,000 pascals. scientists studied the effects of air temperature on the pressure inside american footballs by taking these steps: 1. prepare 100 footballs. 2. measure each football's air pressure. 3. divide footballs into 10 groups. 4. place the groups in different lockers cooled to different air temperatures. 5. after 12 hours, remove the footballs from lockers. 6. measure each football's pressure again. 7. compare the new pressures to the starting pressures. what two terms best describe the variable "air pressure inside the football" in this experiment? independent, qualitative independent, quantitative dependent, qualitative dependent, quantitative
