The red blood cells were placed into an isotonic solution. Water moved into and out of the cells to maintain homeostasis.
Ethonal is produced during b. Alcohol fermentation that converst sugars into ethanol.
Answer: The correct answer for the fill in the blank is High.
Hypotonic solution is the one, which contains less concentration of solute (like salt) as compared to the solvent (water).
In other words, in a hypotonic solution, the concentration of solvent is higher than the concentration of solutes.
Thus, the relative concentration of water ( which is a solvent) in a hypotonic solution is high.
