Chооse the letter оf the inference thаt is most firmly bаsed on the given fаcts. When you stir sugar into a glass of water, the sugar granules break up into individual molecules that disperse throughout the water. The resulting mixture is called a solution. A solution forms when the particles of one substance are dispersed into another substance to make a uniform mixture. Solutions can be mixtures of gases; mixtures of liquids; mixtures of gases and liquids; or mixtures of gases, liquids, or solids. For example, fish get the oxygen they need from the oxygen dissolved in water. A substance that can dissolve other substances is called a solvent. The substance that dissolves in the solvent is called the solute. Water is often called the "universal solvent" because it can dissolve a great variety of substances. Most of the chemical processes of living things take place in water solutions. In fact, life on Earth would not be possible without water.
