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:
The best answer to the question: Evidence suggests that individudals who are overweight actually expend more calories than persons who are of normal weight, would be, A: True.
Explanation:
In recent research studies, especially carried out in Canada, it has been found out that the general belief that obese, or overweight, people, are couch potatoes and it is because of this that they are the way they are, may be wrong. Essentially, these studies followed groups of people and compared obese vs normal-weight people and found out two things: first, obese people move more in terms of steps, than normal-weight people, and two, and most amazingly, overweight people expend more calories than normal-weight people simply because their bodies, given their sheer size, have to use more energy to simply move. Thus, these studies showed that, although not by much, individuals with problems of weight do spend a bit more calories per activity, than normal-weight people.

A is the answer for this problem
The nurse is explaining the recommended dietary allowances (RDAs) to a client seeking nutritional counseling.
<h3>What are RDAs? </h3>
The Recommended Dietary Allowances (RDAs) for critical nutrients have been assessed by the Food and Nutrition Board to be sufficient to cover the known nutrient needs of practically all healthy individuals.
<h3>
History of RDAs. </h3>
The first Recommended Dietary Allowances (RDAs) were published in 1943, during World War II, with the stated purpose of “establishing criteria to serve as a target for appropriate nutrition.” According to “newer results,” it indicated the “recommended daily intakes for the major nutritional needs for people of different ages” (NRC, 1943).
The history of how the RDAs were developed is explained in-depth by the first chair of the Committee on Recommended Dietary Allowances (Roberts, 1958). Updates have been made to the original article.
