which statement correctly explains the rise of liquid in the tube at the end of the experiment?
(1) the concentration of sucrose molecules increased as water molecules entered the bag. this concentration
increase pushed the liquid up the tube.
12) water entered the bag due to the lower concentration of water inside. the extra water pushed the liquid up
the tube as the bag filled.
(3) sucrose indicator entered the bag and reacted with the sucrose molecules. the reaction made the bag
increase in size and pushed the liquid up the tube.
(4) sucrose molecules moved out of the bag and up the tube while water moved out, causing the rise of liquid in
the tube.
