Question 29

# True or False Blood to which an anticoagulant has been added will clot.

Answer 29

FALSE | Blood + Anticoagulant = UNCLOTTED BLOOD

Question 30

# True or False If a blood is mixed with an anticoagulant, blood cells will settle to the bottom of the tube leaving serum at the top of the tube.

Answer 30

FALSE | Blood + Anticoagulant = UNCLOTTED BLOOD = PLASMA
