are not flexible and if they rupture, they can cause you to bleed out.
Blood typing is done in the forensic's field over DNA profiling from Blood becuase
Blood typing is inexpensive compared to DNA profiling
Blood typing is more complete and is used to individualize blood as evidence
Blood typing takes a longer amount of time and therefore is more reliable
Blood typing requires the presence of a nucleus on cells

true
false

Agglutination
grouping
clumping

50% A, 25% AB, 25% B
Blood Typing works because it identifies the presence of particular proteins embedded in the cell
true
false
A person can have more proteins than the ones given by the ABO blood type and the Rh factor. This makes some blood types more unique
