water and sand there is dissolved sugar or salt with sand
immiscible heavy solid particles in a liquid which could settle down when mixed together
Fog is a mixture of water and air, which is itself a mixture..
A mixture
ones which do not bond of chemically react eg. sand salt and water is a mixture. to separate you just filter the sand and then heat the salt and water. they do not chemically combine.

A mixture
The definition of a homogeneous mixture is 'A mixture of two or more substances that cannot be easily separated by common physical means (ie settling, filtration, etc.).Samples from different parts of this mixture have the same composition.' So I suppose it depends on the kind of cookie. A chocolate chip cookie is NOT and example of a homogeneous mixture, it is an example of a hetrogeneous mixture. However a sugar cookie or shortbread cookie IS an example of a homogeneous mixture.
