plasma
The liquid portion of a clotted specimen is called serum. Serum is the clear, yellowish fluid that separates from clotted blood after coagulation. It contains water, electrolytes, antibodies, and other substances.
A specimen that had clotted and has been spun down yields serum, which is the liquid component of blood after clotting factors have been removed. This serum can be used for various diagnostic tests to assess the levels of different analytes in the blood. It is important to ensure that the serum is clear and free of any clots or particles before analysis.
The fluid above the sediment after centrifugation is called the supernatant.
When you see a specimen clearly down a microscope, it is referred to as having a "clear or sharp focus" where the details of the specimen are in clear view. This indicates that the specimen is properly in focus under the microscope, allowing for accurate examination and observation.

The focus knob is turned to adjust the focus and get a clear image of the specimen under the microscope. Turning the focus knob moves the lenses up and down to bring the specimen into sharp focus.
A solution of salt water (sodium chloride dissolved in water) can be separated through distillation. When heated, the water evaporates and is collected as a liquid, leaving the salt behind. The distillation process allows for the separation of the components based on their different boiling points.
No apple sauce is not a clear liquid! =)

The color of the supernatant liquid in decantation can vary depending on the substances present in the mixture being separated. It could be clear, cloudy, or have a specific color if certain substances are dissolved in the liquid.
The conclusion of focusing with a compound microscope is to ensure that the specimen is sharp and clear by adjusting the focus knobs to bring the specimen into focus. This allows for detailed observation of the specimen's features at different magnifications.
Decantation is a process used to separate a mixture of liquid and solid particles that have settled. Examples include pouring off the clear liquid from a settled suspension of sand in water, or pouring off the liquid portion from a settled mixture of oil and water.
