Mary can only receive blood from O+ & O- blood group but not from her husband (B-) or daughter (B+).
<h2>Description of Mary's blood group</h2>
Mary's blood group is O+ as her husband is B- and her daughter is B+.So, it can be said that the daughter's positive(+) antigen should come from her mother (Mary).
AS O blood groups lack A and B antigens, it can donate blood to all other groups and cannot receive from all groups as it has A and B antibodies in the serum.
<h3>Universal Donor</h3>
- Blood donors with type O- (O negative) red blood cells are known as universal donors, because their red blood cells may be used by people of any blood type.
- Transfusions from O-positive(O+) or O-negative(O-) blood types are the sole options for those with O-positive (O+) blood.
Therefore it can be concluded that Mary's blood group is O+ and she can receive blood from O+ and O- groups only.

Microvilli are the structures of fingerlike projections that greatly increase the absorbing surface of the cells.
<h3>What is Microvilli? </h3>
Microvilli are membrane protrusions that resemble fingers and are sustained by the actin cytoskeleton. They are present in practically all cell types. An increasing amount of research indicates that the highly curved membranes of the dynamic lymphocyte microvilli play a critical role in signal transduction that triggers immunological responses.
The examination of the process that generates curvature and its functional implications in signaling, however, was impeded by difficulties in altering local membrane curvature and tracking the high dynamicity of microvilli. Recent developments in adaptive super-resolution microscopy have helped to partially overcome these technological obstacles.
Therefore the structure that increases the absorbing surface area is called microvilli.
