Maria examines a mixture that appears to be the same throughout. however, when she looks at a sample using a magnifying lens, she can see small droplets of liquid surrounded by another liquid. which conclusion best fits her observations? the mixture is a solution because it has the same appearance throughout the sample. the mixture is a suspension because it is composed of two different-appearing substances. the mixture is a heterogeneous mixture because one liquid is dissolved in the other. the mixture is a colloid because two different substances can be seen in a small sample.

The correct statement is the last one.

Explanation:

A microscopically insoluble component, which is suspended all through the other substance is known as a colloid. As the existence of an emulsifying agent, that is, a mixture of water and oil becomes a colloidal dispersion.  

Colloidal dispersion is a system in which the droplets, discrete particles, or bubbles of a dispersed phase (oil) are distributed in the other, generally the continuous phase-dispersion medium (water) varying from the dispersed phase in the state of aggregation or composition.  

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
