Which statement best describes the energy requirements for the cell in order to carry out the life process?

• It will use energy stored in the cell membrane.

• It will use energy in the form of ATP.

• It will use the natural energy of the molecule.

• It happens naturally with no energy required at all.

The picture shows a contractile vacuole of a unicellular freshwater organism. The contractile vacuole regulates the flow of water into and out of the cell in an aquatic environment.

What conditions cause the contractile vacuole to fill with water?

• The concentration of water is greater outside the cell than inside the cell.

• The temperature of water in the vacuole is higher than the temperature of its environment.

• The concentration of water inside the cell is the same as the concentration outside the cell.

• The temperature of water in the vacuole is lower than the temperature of its environment.
