A person whose red blood cells agglutinate with anti-B antibodies BUT NOT anti-A antibodies is type _________.
asambeis [7]

A person whose red blood cells agglutinate with anti-B antibodies BUT NOT anti-A antibodies is type AB.

<h3>What is an agglutinate?</h3>

Agglutination is the process by which specific antibodies to antigenic components on the surface of red blood cells or inert particles (direct agglutination) or to antigenic components adsorbed or chemically attached to red blood cells or inert particles produce clumps of cells or inert particles (passive hemagglutination and passive agglutination, respectively).

When antibodies on one RBC attach to the antigen on another RBC, a process known as agglutination, globular to amorphous, grape-like aggregates of RBCs are formed. RBC agglutination supports immune-mediated hemolytic anemia when it is present (IMHA). The majority of IMHA instances do not exhibit agglutination, but when it does, immunoglobulin M (IgM) is the most frequently implicated because of its pentavalent nature. Agglutination, however, might be brought on by a very thick IgG antibody coating of the RBC membranes. Agglutination is typically regarded as IMHA's diagnostic sign.

Distinguish between a waxing moon and<br> a waning moon.
Dmitrij [34]

Answer:

Waning is the opposite, or decreasing after a full moon, and is always illuminated on the left. Then, there is a waxing or waning Gibbous moon, which means more than half of the moon is illuminated. Waxing means to increase/get bigger, and waning means to decrease/get smaller.
