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.

A cell wall is a structural layer that surrounds some types of cells, situated outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides cells with both structural support and protection, and also acts as a filtering mechanism. Cell walls are present in plants, fungi and prokaryotic cells, where a major function is to act as pressure vessels, preventing over-expansion when water enters the cells. Cell walls are absent from mycoplasmas.

Control rods are an important technology for maintaining the desired state of fission reactions within a nuclear reactor. They constitute a real-time control of the fission process, which is crucial for both keeping the fission chain reaction active and preventing it from accelerating beyond control.
