3.Medicate the infected area to the best of your abilities
Answer: a) Basophils
Explanation:
MHC Receptors are the Major Histocompatibility Complex (MHC) are a set of proteins that are essential for the recognition of what molecules belong to the organism, and which ones are foreign. There are 3 classes of MHC receptors. It is an essential component of the acquired immune system.
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.
ANSWER: CASE-CONTROL STUDY
EXPLANATION:
An epidemiology expert will make use of a Case-control Study for proper determination of association or linkage between the oil spill and the disease outbreak (arthritis).
Case-control Study provides an observational experiment between two existing groups (two reservoirs) differing in outcome (affected and not affected), they are highlighted and compared on the basis of a context (disease outbreak; arthritis).
However, the known group is regarded as the control group and it provides a substantial guide to the confirm the validity of other experimental groups in relation to the general context (outbreak of arthritis).
