Answer:
b) blastic red blood cell (RBC).
Explanation:
In excess of 340 blood group antigens have now been described that vary between individuals. Thus, any unit of blood that is nonautologous represents a significant dose of alloantigen. Most blood group antigens are proteins, which differ by a single amino acid between donors and recipients. Approximately 1 out of every 70 individuals are transfused each year (in the United States alone), which leads to antibody responses to red blood cell <u>(RBC) alloantigens</u> in some transfusion recipients. When alloantibodies are formed, in many cases, RBCs expressing the antigen in question can no longer be safely transfused. However, despite chronic transfusion, only 3% to 10% of recipients (in general) mount an alloantibody response. In some disease states, rates of alloimmunization are much higher (eg, sickle cell disease). For patients who become alloimmunized to multiple antigens, ongoing transfusion therapy becomes increasingly difficult or, in some cases, impossible. While alloantibodies are the ultimate immune effector of humoral alloimmunization, the cellular underpinnings of the immune system that lead to ultimate alloantibody production are complex, including antigen consumption, antigen processing, antigen presentation, T-cell biology.

<h3>What is
information?</h3>
Information is an amorphous concept that refers to things with the ability to inform. At its most basic, information refers to the interpretation of what can be sensed.
Facts and text features such as a table of contents, pictures, captions, bold print, and a glossary are examples of informational text characteristics. These characteristics assist the reader in finding information, supplementing information presented in text, drawing the reader's attention to key words, and explaining what words mean.
Definition speeches, demonstration speeches, explanatory speeches, and descriptive speeches are the four types of informative speeches. A definition speech explains the meaning, theory, or philosophy of a specific topic about which the audience is likely to be unfamiliar.
