What is coagulation test?
When you cut yourself, clotting stops the blood from becoming excessive. Your blood should not clot as it flows through your veins, though. These clots have the potential to develop and move through your bloodstream to your heart, lungs, or brain. A heart attack, stroke, or even death could result from this.
Coagulation assays assess the speed and consistency of blood clotting. Your doctor can use testing to determine your risk of excessive bleeding or the occurrence of clots (thrombosis) in one of your blood arteries.
Venous blood samples for coagulation assays should be drawn into a blue top tube containing 3.2% buffered sodium citrate to produce whole blood samples with a 9:1 blood to anticoagulant ratio.

Aquatic organisms greatly depend on the abiotic actors of an aquatic environment. Waves moving through the aquatic environment also influence the organisms living there. Depending upon the tidal zones, the organisms varies. Many aquatic organisms grow well in the intertidal zone can live in dry environment for a longer period of time. These organisms are also well adapted to withstand the damages that might be caused by the repeatedly pounding wave actions. Such organisms have tough exoskeleton (strong shell) to protect them from wave damage.
Some coastal plants are firmly attached to the rocks o that these are not torn away by the wave action. These plants have small, tough feather-like leaves.
