The correct answer is:
b) milk
Explanation:
- Milk is a heterogeneous mixture because it consists of different components that are not uniformly distributed throughout the mixture.
- In milk, you have various substances like water, proteins, fats, vitamins, and minerals that do not mix completely and can be visibly distinguished from each other.
- Unlike homogeneous mixtures where the components are evenly distributed, heterogeneous mixtures have visible boundaries between the different substances.
- For example, when you look at a glass of milk, you can see that it has a cloudy appearance with particles of fat and protein suspended in the liquid, showing that it is not uniform in composition.
