Yes, O positive can donate red blood cells to AB negative. O positive is a universal donor for red blood cells, meaning it can be transfused to individuals with any blood type. However, O positive donors are not universal plasma donors for AB negative recipients.
Just like any material, it may, or may not, be electrically neutral. What makes it a plasma is that many of its atoms are ionized - but of course the ionization process produces both positive and negative charges (the positive ions, and the electrons). If the original gas had a zero net charge, then (due to the law of conservation of charge) the resulting plasma will also have a zero net charge.
The difference between a gram positive and gram negative bacteria is the thickness/presence of the peptidoglycan layer secreted on the outside of the plasma membrane
A person who is B positive will have B antigens on their red blood cells and anti-A antibodies in their plasma. This blood type is compatible for transfusion with B positive, B negative, O positive, and O negative blood types.
Yes, Bacillus subtilis is negative for the coagulase test. Coagulase is an enzyme produced by some bacteria (such as Staphylococcus aureus) that causes blood plasma to clot, resulting in a positive test. Bacillus subtilis does not produce coagulase, so it will not clot the plasma and will have a negative test result.
It depends what you define as "Blood". Type AB, Rh positive recipients may receive whole blood (rarely used in modern transfusion medicine) from AB, Rh positive or negative donors. They may also (generally) receive red cell transfusions from any ABO and Rh blood type. They may receive platelets from any ABO, Rh donor type, but may require removal of residual incompatible plasma from the platelet product prior to infusion. An AB patient may only receive AB plasma. AB negative recipients may receive whole blood from an AB, Rh negative donor, red cells from any ABO, Rh negative donor, platelets from any ABO, Rh negative donor (with possible plasma reduction), and only AB plasma. Concerning the transfusion of Rh positive cellular components to Rh negative recipients; ABO compatible, Rh positive red cells may be transfused to Rh negative patients IF there are no compatible, Rh negative products available, transfusion cannot wait for units to be imported, anti-D antibodies are not present in the patient's plasma and the patient is a male, or a female of non-child bearing age.
No, it is not recommended to give O negative blood to an O positive patient, as the patient has antibodies that could react against the negative blood type. It is safer to give O positive or Rh positive blood to an O positive patient.
In crossmatching you don't actually mix the whole blood samples. You will mix the red blood cells of the donor with the plasma of the patient. So if the patient is Rhesus positive, it wont have antibodies in the plasma against the Rhesus factor on the red blood cells of the donor. So a crossmatch with either a negative or positive donor will be allright. So in this case, it is indeed possible.
It depends on what blood component is to be transfused. If O, Rh negative whole blood is to be given, the patient may be O, Rh negative or O, Rh positive. If O, Rh negative red cells are to be transfused, the patient may be any blood type (generally).
Usually, the total charge of plasma is neutral. Of course, there are exceptions. As the atoms are energized, electrons are released into the system. That release leaves a bunch of positive and negative charges.
Plasma is a neutral mixture of positive and negative ions some of which are mobile, e.g electrons in metals .
no , it is not possible
That sounds like a plasma. In a plasma, most of the atoms are ionized.
Yes. Rh status is unimportant in transfusing plasma because Rh antigen are on red cells only. The amount of red cells in a unit of plasma is insignificant. If the unit looks orange-reddish, an Rh positive plasma should not be given to an Rh negative plasma if possible.

Type o negative and positive can donate to any blood type because it is the most interchangeable blood type i have people calling me all the time for my o neg blood and i love to donate when i can i love the fact that 1 pint saves 3 lives and you give a pint each visit it hurts the least out of donating plasma and bone marrow though
Yes, plasma can carry a negative charge due to the presence of free electrons that are not bound to atomic nuclei. These free electrons can move independently and give the overall plasma a net negative charge.
