Answer:
Salt triggers osmosis by attracting the water and causing it to move toward it, across the membrane. Salt is a solute. When you add water to a solute, it diffuses, spreading out the concentration of salt, creating a solution. If the concentration of salt inside a cell is the same as the concentration of salt outside the cell, the water level will stay the same, creating an isotonic solution. Cells will not gain or lose water if placed in an isotonic solution. The raisin would swell. (please mark brainliest)

<h3>What is the circulatory system?</h3>
To obtain oxygen into the blood, the circulatory system (cardiovascular system) pumps blood from the heart to the lungs. The remainder of the body receives oxygenated blood from the heart via arteries. Oxygen-depleted blood is returned to the heart by veins to restart circulation.
Heart and blood vessels problem directly affect the circulatory system. Blood vessel disease (Vasculopathy) The blood arteries that transport oxygen and nutrients throughout your body and eliminate waste from your tissues are affected by vascular disease (also known as vasculopathy). Plaque, which is composed of fat and cholesterol, slows or obstructs blood flow in your arteries and veins, causing common vascular issues.
