Answer:
If you refer to something as a security blanket, you mean that it provides someone with a feeling of safety and comfort when they are in a situation that worries them or makes them feel nervous.
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.
Teaching a class on the dangers of smoking.
<h3>What are primary health prevention?</h3>
Primary prevention entails taking action against a vulnerable group or individual. Primary prevention aims to stop a disease from ever developing. Healthy people are hence its intended audience. To stop a disease from developing in a susceptible person into a subclinical disease, it is frequently implemented activities that restrict risk exposure or boost the immune of those at risk.
Programs for health education, vaccinations, and physical and nutritional fitness activities are all forms of primary prevention that aim to promote health.
The first step in promoting health is to educate others about the dangers of smoking.
I understand the question you are looking for is this:
