Heterogeneous means that there are different compounds in a sample. Heterogeneous is a term used with mixtures and the way I like to think about it is:
If you have cheerios, apple jacks, and coco puffs in a bowl you have a heterogeneous mixture because you can physically separate the cereals from each other. If you can not physically separate out the components, it is not a mixture.
A heterogeneous mixture is a mixture in which you can see more than one phase.
homogeneous
No, a mosquito is an organism and not a mixture. A heterogeneous mixture is a combination of different substances that are not uniformly distributed.
Fruit salad is a heterogeneous mixture because it contains different components that can be visually distinguished, such as pieces of various fruits.
Heterogenous, because the components are unevenly mixed throughout. However, smooth salsa is more homogeneous, and chunky is more heterogeneous. ;)
River water is generally a heterogeneous mixture based on the different components it is carrying. Water by definition is not an element, rather a molecule comprised of them.
A mixture is two or more substances combined together with actually reacting chemically. So, be it homogeneous or heterogeneous, a mixture is a mixture if it fits this definition.
Ca is an element. It is a pure substance, which, by definition, is homogeneous matter, but is not a mixture.
hetergeneous
A flower is a heterogeneous mixture.
The separation of constituents in a heterogeneous mixture creating a non-uniform distribution of concrete mixture.
If you mean salt & pepper in the same container, I would say heterogeneous mixture, but salt by itself would be a compount (NaCl?), while pepper would likely be a homogeneous mixture (milled black pepper).
Heterogeneous mixture.

Sand+salt: a heterogeneous mixture.
A heterogeneous mixture is a mixture in which you can see more than one phase.
