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.
1 - They all are solids due to the strong electrostatic force
<span>2 - They also have high m.p and b.p. </span>
<span>3 - It conduct electricity in molten state or in aqueous solutions </span>
The probability of transmitting both traits to his son is Zero. This is because the son has one X chromosome and one Y chromosome (XX), therefore since the traits are linked to the X chromosomes, it means the son will only be a carrier but will not show the trait phenotypically.
The answer u r looking for is- D* failure of the immune system to distinguish self from nonself. Hope I’ve helped ;)
Answer:
The dominant phenotypes are Long flagella and one vacuole, and the recessive phenotypes are small flagella and two vacuoles.
Explanation:
As you can see in the attached table
1. For the size of the flagella we gave that:
- 241 organisms have long flagella
- 79 organisms have short flagella,
As there are more organisms with long flagella we can conclude that this is the dominant phenotype while the short flagella is the recessive phenotype.
2. For the number of vacuole we have:
- 247 organisms have one vacuole
- 73 organisms have two vacuole
As there are more organisms with one vacuole we can conclude that this is the dominant phenotype while having two vacuoles a is the recessive phenotype.
Then
Dominant phenotypes = Long flagella and one vacuole
Recessive phenotypes = Short flagella and two vacuoles
