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 environement. What condtions cause the contracile vacuole to fill with water? Your answer: The concentration of water is greater outside the cell than inside the cell. The concentration of water inside the cell is the same as the concentration outside the cell. The temperature of water in the vacuole is higher than the temperature of its environment.

Answer:

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

Explanation:

In living cells, water moves by Osmosis across the cell membrane, which acts as the semi-permeable membrane. Osmosis is the movement of water molecules from a region of high water concentration (low solute concentration) to a region of low water concentration (high solute concentration).

The contractile vacuole of this freshwater organism helps regulate water intake and exit by storing excess water. According to osmotic flow, water will flow into the organism via its cell membrane (semi-permeable membrane) because the concentration of water outside the cell is high than inside the cell, hence, this causes an osmotic gradient causing water to flow into the cell. The water that flows into the cell is stored in the Contractile vacuole.

Can someone please help me I am doing a project were I have to wet a cloth and wrap it around a thermometer. Then I have a dry cloth and wrap it around another thermometer. The degrees for the wet one was 40 degrees and the dry one was 35. I had to do it three times and the dry one was still 35 on three trys and the wet one was still 40. now calculate the average.
