What else can I help you with?
Are erythrocytes true cells?
No erthrocytes are not true cells because they lack to characters of true cell one is presence of nucleus and other is nature of multiplication i.e. why they are not called cells but knwon as reb blood corpuscle
Do shellfish have red blood cells?
No, shellfish do not have red blood cells. Instead, they have a fluid called hemolymph that circulates nutrients and oxygen throughout their bodies. Hemolymph is colorless or transparent and does not contain red blood cells.
Does leukemia occur as a result of an excess or lack of white blood cells?
Leukemia is a type of cancer that results in an overproduction of abnormal white blood cells in the bone marrow. This leads to a decrease in the production of normal blood cells and can cause a lack of healthy white blood cells.
What cells have visible projections amongst muscle cells red blood cells and sperm cells viewed under a light microscope?
Muscle cells have visible projections called myofibrils, red blood cells lack visible projections due to their biconcave disc shape, and sperm cells have a visible projection called a flagellum which helps in motility.
Does blood contain Mitochondria?
White blood cells have. But erithrocytes lack many
How does type 0 blood differ from A, B and AB blood types?
Your blood type is determined by what type of antigen you have in your body. Each person has different antigen's or lack there of in the blood. A blood test is used to determine what these are.
Where does the positive and negative for blood come from?
The positive and negative blood types come from the presence or absence of certain antigens on the surface of red blood cells. Blood type A has A antigens, B has B antigens, AB has both A and B antigens, and O has neither A nor B antigens. The positive or negative designation refers to the presence or absence of the Rh factor antigen.
What antigens are expressed if a person is blood type AB negative?
My daughter is AB negative , I am B positive and her dad it A negative
What cell is not and antigen presenting cell?
Red blood cells are not antigen presenting cells because they lack major histocompatibility complex (MHC) molecules, which are required for presenting antigens to T cells.
Why is blood group o named as o and not as c or d?
Blood group O is named "O" for "zero" or "null," indicating the absence of A and B antigens on the surface of red blood cells. The naming convention was established by Karl Landsteiner in the early 20th century when he discovered the ABO blood group system. The letters A and B were assigned to the presence of specific antigens, while O signified the lack of these antigens, distinguishing it from other blood groups.
Which cells lack a nucleus?
Red blood cells lack a nucleus.
Are erythrocytes true cells?
No erthrocytes are not true cells because they lack to characters of true cell one is presence of nucleus and other is nature of multiplication i.e. why they are not called cells but knwon as reb blood corpuscle
How does ABO blood typing work?
in the ABO blood type, there are two main anitgens or agglutinogens, A and B. A type has the A antigen, B type B antigen, O none, and AB both the A and B antigen. Thus, O is a universal donor due to its lack of antigens and AB is a univeral reciepient due to the fact that it has both antigens. btw, antigens= complex sugar molecules attached to the membrane of RBCs
What are the 4 blood types?
There are four types of human blood, grouped into different catogories. Type 'A', 'B', 'AB' and type O. Each letter refers to a kind of protein or antigen, on the surface of the red blood cells. The surface of red blood cells in Type 'A' blood, has antigens known as A-antigens. Type 'B' blood is determined by it's lack of antigens, which are carried to the surface of red blood cells. Type AB blood is considered the universal recipient because people with this type can receive any blood type. Type O blood is considered the "universal donor" because it can be donated to people of any blood type. Antigens: An antigen is a substance that prompts the generation of antibodies and can cause an immune response
Cells that lack nuclei are?
Red Blood Cells
How are red blood cells unique?
Red blood cells are the only cells in the body that lack a nucleus.
Do shellfish have red blood cells?
No, shellfish do not have red blood cells. Instead, they have a fluid called hemolymph that circulates nutrients and oxygen throughout their bodies. Hemolymph is colorless or transparent and does not contain red blood cells.
