The reason why taq polymerase is used is because it is thermostable, meaning that it can remain intact and reactive after being exposed to the cycles of high temperatures that are used in PCR (an upwards of 94 degrees Celsius). If human DNA polymerase were used instead, it would immediately unfold and become inactive after the first round of high temperatures, effectively ceasing the PCR.
Answer:
В, С, А
Explanation:
The process of clotting is known as the hemostasis which takes place in three steps: the vascular spasm, the formation of a plug of platelets and the coagulation.
In the given question, step B shows the process of vascular spasm in which the vascular blood vessels becomes constricted due to injury. After this, the platelets present in the blood starts accumulating at the site of injury. These platelets stick together and form a plug-like structure at the site of injury.
Later, step A takes place that is fibrin protein present in the blood starts forming a mesh-like structure which does not allow the bleeding and this process is known as coagulation.
Thus, the selected option is the correct answer.

The complete blood count or CBC is a pathological test, which measures the number of red blood cells (RBCs), white blood cells(WBCs), platelets and other vital compounds present in a definite amount of the blood.
The CBC allow detection of the presence of any ailment, which can affect the normal physiology of the blood.
Hence, the acronym for blood test that measures the number of RBCs, WBCs and platelets is CBC.
