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.

Leone Lattes devised a technique for determining the blood group of a dried bloodstain, which he applied to criminal investigations.
An easy technique for identifying the blood type of a dried bloodstain was invented in 1915 by the Italian scientist Leone Lattes.
In 1939–1940, the Rh blood group system—which divides blood into groups depending on whether the Rh antigen is present or not—was created. Since then, more than a hundred various blood factors have been identified.
These characteristics can be utilized to pinpoint the particular groups to which possible suspects may belong because they show up unevenly in the population.
As different blood factors are identified in a sample, the proportion of individuals who have that particular combination of factors decreases and the sample becomes more unique.

Answer:
collenchyma tissue is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials. It provides support, structure, mechanical strength, and flexibility to the petiole, leaf veins, and stem of young plants, allowing for easy bending without breakage. The stretchy properties of the strands of celery are due to collenchyma tissue. Collenchyma tissue is found immediately under the epidermis, young stems, petioles, and leaf veins. Also, it has been seen in avocado fruit hypodermis. Collenchyma cells may or may not contain a few chloroplasts, and may perform photosynthesis and store food.
