The Correct Answer and Explanation is:
Garlic and Avocado: Classification and Explanation
1. Garlic:
Garlic is a mixture, specifically a heterogeneous mixture.
Explanation:
Garlic is composed of multiple substances, including water, carbohydrates, sulfur compounds (like allicin), vitamins, minerals, and fibers. These components are not chemically bonded together in fixed ratios, and their distribution is not uniform throughout a garlic clove. For example, the concentration of sulfur compounds may be higher in one part than another. Because you can observe and separate its different parts through physical means (like cutting, crushing, or extracting oils), garlic is not a pure substance. Its variability in texture and chemical composition across different cloves and even within a single clove classifies it as a heterogeneous mixture.
2. Avocado:
Avocado is also a mixture, specifically a heterogeneous mixture.
Explanation:
Avocados contain a variety of components such as water, lipids (healthy fats like oleic acid), proteins, carbohydrates, fibers, vitamins (like vitamin E and C), and minerals (such as potassium). These substances are mixed together but not in a uniform way. For example, the flesh near the seed may have different water or oil content than the outer flesh. Furthermore, the texture varies throughout the fruit—some parts are more fibrous, while others are smoother. These features make it a heterogeneous mixture, as the composition and physical properties are not consistent throughout the avocado. It is not a pure substance because its components are not chemically combined in fixed proportions, and it can be physically separated into its parts.
Summary:
- Garlic – Heterogeneous mixture
- Avocado – Heterogeneous mixture
Neither garlic nor avocado is a pure substance because both contain multiple components that are not chemically bonded in a fixed ratio, and both display non-uniform composition.
