Bison are big mammals that belong to the family Bovidae. Male bison charging each other shows the competition among organisms of the same species.
<h3>What is the competition?</h3>
Competition is the ecological relationship between the organism of the ecosystem that can be positive, neutral or negative. It can be between species or among the member of the species.
Two bison fighting each other shows the competitive relationship between both of them as they both belong to the same species and can fight for territory, food, resources, reproduction and many others factors.
Therefore, the Bison charging shows competitive relationships among the same species.

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.
D. They help plants get nutrients and water form soill This is called mutualism.
