Answers
Answer:
1 =Th eshing is the process of loosening the edible part of grain from the chaff to which it is attached. It is the step in grain preparation after reaping. Threshing does not remove the bran from the grain. Threshing may be done by beating the grain using a flail on a threshing floor
Explanation:
2=Wind winnowing is an agricultural method developed by ancient cultures for separating grain from straw. It can also be used to remove pests from stored grain. Winnowing usually follows threshing in grain preparation.
3= 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. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration, or electromagnetism , 4 =water which collects as droplets on a cold surface
5= All the solids settle down at the bottom of a beaker and on top, a clear layer of liquid is obtained. Decantation is defined as the separation process in which two immiscible liquids are separated. This is done by pouring out the clear upper layer of liquid
