RRB ALP & Technician
20/08/2018 (Shift-I)
2018
✓ Answer:A7.0 to 7.8
The source key selects 7.0–7.8. This is imprecise: different body fluids have different pH values, and normal blood pH is tightly regulated around 7.35–7.45.
746
Human blood platelets release _____ which helps in blood clotting.
RRB NTPC (Stage-I)
27/04/2016 (Shift-III)
2016
✓ Answer:AProthrombin
The source key gives prothrombin. The wording is inaccurate: prothrombin is primarily made in the liver and circulates in plasma; platelets provide surfaces and release substances that promote clotting.
