This question presents a two-blank fill-in-the-blank about solutions. The first blank asks for the descriptor of a solution’s overall nature, and the second blank asks for the term that names the dissolved substance.

First, consider the concept of a solution. A solution is a homogeneous mixture, meaning its composition is uniform throughout and the different components are not visibly distinguishable. Therefore, the word that fits the first blank is homogeneous, since it describes the uniform nature of a solution.

Second, in a solution, there are two components: the solvent, which is the substance present in the larger amount, and the solute, which is the substance dissolved in the solvent. The correct term for the dissolved substance that is present in a smaller amount is solute. This matches the common chemistry definitions used when describing solutions.

If one were to consider alternative phrases, a heterogeneous mixture would imply visibly different components, which is not the case for a solution, so heterogeneous would be incorrect for the first blank. Also, calling the dissolved component simply a substance without naming its role would be less precise; the established terminology distinguishes solvent and solute, with solute being the dissolved component.

To summarize the reasoning: the first blank should be homogeneous because solutions are uniform mixtures, and the second blank should be solute because it is the component that is dissolved in the solvent to form the solution. Note that the provided answer options are blank in this item, so the evaluation is based on the fundamental definitions rather than multiple-choice option analysis.
