Yes, milk is considered a homogeneous mixture. This means that its components are evenly distributed throughout the substance, and you cannot easily distinguish one part from another using the naked eye.
To elaborate, milk is made up of water, fats, proteins, lactose, vitamins, and minerals. When you look at milk, it appears uniform, and these components blend together to form a consistent liquid. Even though milk contains fat globules, which can separate out over time, when milk is properly homogenized, these fat globules are broken down into smaller sizes and distributed more evenly throughout the liquid. This process prevents them from rising to the top and allows milk to maintain its uniform appearance, which is characteristic of a homogeneous mixture.
In contrast, if milk were a heterogeneous mixture, you would be able to see clear differences in composition when you look at it, like you would with oil and water. Since milk does not display these differences when well-mixed, we classify it as a homogeneous mixture.
