None of them. It is a complex system of biochemicals.
None of them. It is a heterogeneous mixture.
A compound is either Molecular or Ionic in nature.
Compound it cant be an element because its a diatomic or polyatomic cnt remember which one but either way its not an element its a compound. Compound it cant be an element because its a diatomic or polyatomic cnt remember which one but either way its not an element its a compound.
Actually it isn't either, nickel is an element. Look on the periodic table and you will see this, its symbol is Ni.
Brass is homogeneous. To test this, I'm still finding it. But brass is homogeneous.
None of them. It is a heterogeneous mixture.

The purest sand is a compound, silicon dioxide. Most ordinary sand, however would contain some other materials and could be either a homogeneous or a heterogeneous mixture.
The main constituent of common table salt is a compound, with the formula NaCl and the name of sodium chloride. Actual table salt may be a mixture, with small amounts of other materials in it.
a solution can either be homogeneous or heterogeneous. if you can see the parts, it is heterogeneous. if you cant see the parts, it is homogeneous (an example is milk)
A compound is either Molecular or Ionic in nature.
A protein can not be an element, because every protein must contain at least four elements: carbon, hydrogen, oxygen, and nitrogen. A pure protein is a compound, but it may be mixed either homogeneously or heterogeneously with other molecules that are so chemically similar that they are difficult to separate.

a pure substance. either a compound or an element. Also, a solution, which is a homogeneous mixture, not a pure substance.
