D. They can be separated by physical processes.



Answer :

Final answer:

Mixtures are combinations of substances that retain their individual properties, can be separated by physical methods, and can be homogeneous or heterogeneous.


Explanation:

Mixtures are combinations of two or more substances that are not chemically bonded together, allowing for their individual properties to remain unchanged. One characteristic of mixtures is that they can be separated by physical processes such as filtration, distillation, or evaporation. Mixtures can be either homogeneous (uniform composition throughout, like sugar dissolved in water) or heterogeneous (non-uniform composition, like a mixture of sand and water).
