Answer:
If red blood cells are placed in a hypertonic solution, they will shrink because the water moves out of the cell through osmosis. When red blood cells are places in hypotonic solution they swell and rupture because the water moved in the cell through osmosis.
Explanation:
If red blood cells are placed in 1400mOsm of NaCl, the cell volume will be lost because the wayer in the cell moves out due to higher concentration of salt outside, they will shrink.
Similarly if the red blood cells are places in urea and NaCl the cell will again shrink.
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 correct option is: a. PIH
Explanation:
The PRH or the prolactin-releasing hormone is the hormone responsible for stimulating the release of prolactin from the anterior pituitary gland. Prolactin then stimulates the mammary glands of the mammals, usually females, to produce milk.
The PIH or the prolactin-inhibiting hormone, also known as dopamine, inhibits the production of prolactin and thus blocks the milk formation in males and non-pregnant females.
