Answer:The word "heterogeneous" means consisting of dissimilar or diverse ingredients or constituents. It implies a lack of uniformity or homogeneity. The opposite of heterogeneous is homogeneous. Here's a breakdown with examples:In a mixture: A heterogeneous mixture is one where the components are not uniformly distributed. You can visually distinguish the different parts. Examples include: - Sand and water: The sand settles to the bottom, clearly separate from the water. - Oil and water: These two liquids don't mix; they form distinct layers. - A salad: Lettuce, tomatoes, and cucumbers are visibly different components.In materials science: A heterogeneous material has different phases or compositions throughout its structure. Examples include: - Concrete: A mixture of cement, sand, gravel, and water with visibly different components. - Wood: Composed of different types of cells and structures.In populations: A heterogeneous population is one with a diverse range of characteristics, such as age, ethnicity, income level, or beliefs. Examples include: - A large city: People from various backgrounds and walks of life live together. - A diverse classroom: Students with different learning styles, abilities, and cultural experiences. In short, anything that's not uniform or consistently the same throughout is considered heterogeneous.
