The human HLA system (human leukocyte antigen) is responsible for identifying and rejecting foreign tissue in our bodies. In humans the HLA system is composed of
hundreds of multiple alleles and can have at least 30,000,000 different genotypes.
An infinite number of combinations of these genotypes is what makes the cells in
our body have a recognition code that is unique for every individual. Which
statement best summarizes an effect of the HLA system.
The HLA system is responsible for problems when the incorrect
blood type is transfused into a recipient.
The HLA system is what causes the rejection of organ transplants
unless it is suppressed by medication
o
The HLA system is responsible for the increase in the number of
bacteria species resistant to antibiotics.
O
The HLA system is destroyed by the infection from the human
immunodeficiency virus resulting in AIDS.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.

it's a.true. i'm kind of smart.
