Blood is made up of red and white blood cells, platelets and plasma. The plasma consists of water (mostly) and dissolved nutrients. When blood is exposed to air, the blood will clot, due to aggravation of the platelets. Then you get a forming scab that will help heal the part that the blood is being exposed from.

Your answer is correct! The answer is clear sunny!
Vacuole being cellular organelle found in cells serves few important functions for the cells. It's usually the biggest cell organ within the cell. Its main function is the store nutrients and waste materials. It additionally functions to take care of the correct pressure inside the plant cells to provide structure and support for the growing plant.
Further Explanation:
The bubble-like structures present in a cell is known as the vacuoles. These vacuoles may store food or any kind of nutrients that a cell may require to survive, not solely this but vacuoles will even store waste product, so that the rest of the cell is protected against contamination. Vacuoles are membrane(tonoplast) bound sacs that are present within the protoplasm of the cell. There are many functions of vacuoles. the inner fluid within the cavity is understood as the cell sap. In mature plant cells, the vacuoles are of a bigger size and provide structural support to the cells. The vacuoles additionally perform as the storage organ, waste disposal organ, protection organ and for growth. Some vacuoles store toxic substances and waste materials that taste Bitter to the insects. The ability to regulate the turgor pressure in a plant cell is the important characteristic function of the central vacuole. Turgor pressure determines the rigidity of the cell.
The above-named functions are the few functions of the vacuole.
