Question 7

Match between columns
                        Premises: RhS1U1P1+S1S1P0 molecules in the body of an RhS1U1P1 - S1S1P0 woman represents these.
These directly attack the foreign cells of an incompatible skin graft.
These cells recognize cell-surface antigens and initiate the proliferation of lymphocytes.
These bind (as in a lock-and-key mechanism) to foreign proteins.
These cells do not need to encounter an antigen-MHC complex to take action.
Bacteria and viruses in the blood are attacked by proteins produced by these.
These produce immunoglobulins in response to the reinvasion by a virus.
These cells produce antibodies.
These cells destroy cells infected by viruses.
These cells scavenge dead cells and attack bacteria directly.

Accepted Answer

The Answer of antigens and helper T cells and memory is...
