. 6.What is agglutination?

7. What is agglutinogen?

8. What are the preformed antibodies in human blood?

9. Which antibody in the blood is formed after exposure to antigen?

10. What is its consequences?

Expert Solution

Q7-

agglutinogen is any antigen, or foreign cell, toxin, bacteria, or anything else that gets the immune system reacting, that makes your body generate agglutinins for defence.

Q6-

Agglutination is the process that occurs if an antigen is mixed with its corresponding antibody called isoagglutinin. Its process of clumping of cells for recognition of blood group.

Q8-

The Preformed antibodies are derived from the blood serum of previously infected people or animals, are often administered in an antiserum to another person in order to provide immediate, passive immunization against fast-acting toxins or microbes.
For example- Individuals with type A blood have preformed antibodies to the B antigen circulating in their blood plasma.
So These antibodies, referred to as anti-B antibodies, will cause agglutination and hemolysis if they ever encounter erythrocytes with B antigens in the blood.

Q9-

IgM antibody

Q10-

After IgM antibody formation and subsequent antigen exposure, follicular B cells undergo isotype switching, resulting in increased production of IgG, IgE, or IgA for defence mechanism.

If three points were added to every score in this distribution, what would be the new standard deviation. Remember, you have already calculated population standard deviation in a previous problem. This problem requires two answers.
