Question

these are mixtures that are not the same throughout
heterogeneous mixtures
water
homogeneous mixtures
solutions

Explanation:

To solve this, we analyze the definitions:

• Heterogeneous mixtures: Mixtures with non - uniform composition (not the same throughout).
• Water is a compound, not a mixture.
• Homogeneous mixtures (including solutions) have uniform composition throughout.

So the option that matches "mixtures that are not the same throughout" is heterogeneous mixtures.

Answer:

A. heterogeneous mixtures
