Final answer:
In a heterogeneous mixture, the individual components can be visually distinguished. Examples of the choices provided are salad, vegetable soup, and trail mix.
Step-by-step explanation:
A heterogeneous mixture is a type of mixture in which the components can be seen, as there are two or more phases present. Salad, vegetable soup, and trail mix are examples of heterogeneous mixtures because you can see the individual components. In a salad, for instance, you can distinguish the lettuce from the tomatoes and other ingredients. In a vegetable soup, you can see the different vegetables floating in the broth. Similarly, in trail mix, you can differentiate between the nuts, raisins, and chocolate pieces. On the other hand, water, apple juice, and brass are homogeneous mixtures as their composition is uniform throughout.
