What do b cells make when they recognize antigns?
B cells make antibodies when they recognize antigens.
How do co-dominant alleles work?
Co-dominant alleles are both expressed, because both are translated into RNA. One of the best examples of co-dominance is human A/B blood type. The thing that differentiates A and B blood types is the antigens found on the surface of the blood cells. A person with two alleles for A-type antigens will have only A-type antigens, and a person with two B-type alleles will have only B-type antigens. However, a person with one A-type allele and one B-type allele will have blood type AB. A third allele, O-type, has no antigens on the surface of blood cells, and so is only "expressed" in the phenotype if a person has two O-type alleles (and therefore no antigens on their blood cells.)
What process provides many b cells and t cells that are activated against specific antigens?
Clonal expansion is the process that provides many B cells and T cells that are activated against specific antigens. Clonal expansion is what provides the immune system its strength.
What determine the ABO blood group in the plasma membrane of rbcs?
The ABO blood group is determined by the presence or absence of specific antigen molecules on the surface of red blood cells. These antigens are determined by the inherited genes from our parents. There are three main types of antigens that determine the ABO blood group: A, B, and O. The combination of these antigens results in different blood types: A, B, AB, and O.
Lack of reactivity of T cells and B cells to your own proteins is know as what?
Tolerance of self-antigens.
Foreign antigens pressed into the plasma membrane are recognized by what?
helper T cells B cells so the answer is B for Plato users
What are the A B AB and O blood groups distinguished by?
Blood types are distinguished by the type of antigen on the red blood cells. Type A has A antigens, type B has B antigens type AB has both antigens and type O has none.
Does anybody know what are the 4 blood types ?
Te four basic blood types are O, A, B and AB. They are named for the types of antigens they carry. O has no antigens, A has A antigens, B has B antigens and AB carries both.
Which blood types in terms of the ABA and Rh antigens can be donated to somebody with type AB blood?
B+ here is a guide for you: type A - A antigens B antibodies; type B - B antigens A antibodies; Type AB - A&B antigens and no antibodies; type O - no antigens and A&B antibodies. for the rh you just have to add if it is + or -.
What are the blood types in terms of antigens and antibodies?
"there are at least 24 blood groups and more then 100 antigens that ca be detected on the surface of red blood cells"- from A&P Book.
Do T- Cells respond to antigens by becoming plasma cells?
No. B-Cells do.
Is a persons blood type genetically determined?
Yes. Blood type is determined by the antigens present on the surfaces of red blood cells. There are three types of antigen, A, B and Rhesus. O blood types have neither A or B antigens. A types have A, B have B, and AB have both. Positive blood types have rhesus antigens, and negative blood types do not. Which antigens are produced is genetically determined.
What is the chemical makeup of Type O blood?
Your blood type is determined by antibodies (both/either A and B), and Antigens present (both/either A and B) in your Red Blood Cells. O blood types have both A and B antibodies, and neither A or B antigens.
What do b cells make when they recognize antigns?
B cells make antibodies when they recognize antigens.
Which antigens are present in your plasma if you have type O blood?
Your blood type is determined by antibodies (both/either A and B), and Antigens present (both/either A and B) in your Red Blood Cells. O blood types have both A and B antibodies, and neither A or B antigens. If you are O+ it means you can give blood to anyone. If you are O- it means you can recieve any blood type.
What is an example of a self antigen?
A or B antigens of blood cells
Do Group O types have Antigens?
Your husband would be incorrect, blood types that have Antigens would be type A and B and AB. Type O means you do not have any Antigens in your blood.
