1)mixture
2)threshing
3)winnowing
4)sedimentation
5)filtrate
6)solute
7)solution
8)solublity
Answers
a. A mixture is a material made up of two or more different substances which are combined.
b. Threshing is the process of loosening the edible part of grain from the straw to which it is attached.
c. Winnowing is an agricultural method developed by ancient cultures for separating grain from chaff. It can also be used to remove pests from stored grain. Winnowing usually follows threshing in grain preparation.
d. Sedimentation is the tendency for particles in suspension to settle out of the fluid in which they are entrained and come to rest against a barrier.
e. Filtration is a physical, biological or chemical operation that separates solid matter and fluid from a mixture with a filter medium that has a complex structure through which only the fluid can pass.
f. A solution is a special type of homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.
g. A solution is a special type of homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.
h. Solubility is the property of a solid, liquid or gaseous chemical substance called solute to dissolve in a solid, liquid or gaseous solvent.

Answer:
a substance made by mixing other substances together is called mixture
The process of separating grain from (corn or other crops), typically with a flail or by the action of a revolving mechanism Is called threshing .
Winnowing means to use an air current on grain in order to blow away chaff, or to separate out the best specimens.
Sedimentation is the process of settling or being deposited as a sediment
Filtrate is a liquid which has passed through a filter.
the component of a solution that changes its state in forming the solution or the component that is not present in excess Is called solute.
Solution is the process by which a gas, liquid, or solid is dispersed homogeneously in a gas, liquid, or solid without chemical change.
Solubility is a property referring to the ability for a given substance, the solute, to dissolve in a solvent.
