Which statement correctly explains the rise of liquid in the tube at the end of the experiment?
The concentration of sucrose molecules increased as water molecules entered the bag. This concentration increase pushed the liquid up the tube.
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.

water molecules moved out of the thistle tube
starch molecules moved out of the thistle tube
amber-colored solution moved into the thistle tube
- 101. Multiple Choice
Which statement best explains why these gases are able to move in the directions shown in the diagram?
The CO2 moves out of the capillary and into the alveolus to make more room for the blood to carry O2.
The O2 is needed by the cells, so it is actively transported into the blood. The CO2, which is not needed, is actively transported out of the blood.
The blood coming to the lungs is low in CO2 and high in O2, so the gases each diffuse from a lower to a higher concentration in this area.
The blood coming to the lungs is high in CO2 and low in O2, so the gases each diffuse from a higher to a lower concentration in this area.
