Answer:

) Presence of specific glycoproteins on the cell membrane

Explanation:

When specif glycoproteins(antigens)  or antibody are present on a cell membrane of Red blood cell,they can  be used to identify the blood type.Antigens are substances capable of triggering an immune response in a cells.

In addition,they function in transport of molecules across the RBC. They help in the maintenance of the RBC,and aiding the arrest of cells capable of causing diseases to the body.

Therefore,they are good determinants of blood types,based on this two types of antigens present in a  blood type.

These two antigens  used for classification of blood types are the 1-the ABO antigens 2,the Rhesus antigens.

Essentially,when a WBC produces an antibody ,which is a molecule that defends the body,If this is not compatible,the antibody will recognize it as a foreign body and attack it.Thus such blood types are not compatible. Thus the antibody-antigen reaction are good for knowing and classify blood types.

Antigen can also be glycoprotein,carbohydrate or glycolipids.

Generally blood types are inherited from both parents.Therefore the antigen present on the RBC are combination of the alleles from each parent.

Write your question here. We can't read your mind. Yet.

Let’s think about this, we can already cross out D because that is the small intestine’s function, that isn’t a picture of the small intestine.

We can also cross out A for the answers because the gallbladder is the organ that creates bile and that once again isn’t the picture of that organ.

That leaves C and B.

The stomach produces pepsin and makes hydrochloric acid, this isn’t a picture of the stomach, so that leaves you with C.


The answer to your question is C, since this is a picture of the pancreas, and the pancreas’ job is to produce enzymes that breaks down carbohydrates.
