Which of the following is/are true about antibody structure?
They are made of four polypeptides
The variable region is recognised by phagocytes
The constant region is where the antigen binds
The heavy chains only contain constant regions
Which of the following is/are true of antibody production?
Macrophages engulf and digest pathogens
The antigen of the pathogen is presented on the cell wall of the macrophage
The antigen on the pathogen attaches to an antibody on a T helper cell
T helper cells are activated when they attach to the specific antigen
Which of the following is/are true of antibody production?
Activated T helper cells activate macrophages so they clone by mitosis
Activated T helper cells activate B cells so they clone by mitosis
Plasma cells remain in the blood for years and clone faster if reinfected at a later date
Memory cells produce and secrete specific antibodies into the blood to destroy the pathogen
Which of the following is/are true of antibody production?
Plasma cells and memory cells from same B cell have the same shaped antibody on their surface
T helper cells have antibodies on their surface
Free ribosomes produce the antibodies that are secreted by plasma cells
T help cells activate B cells by releasing a chemical signal
Which of the following is/are functions of antibodies?
Preventing viruses from attaching to host cells
Agglutinating pathogens
Cell lysis
Marking pathogens for faster phagocytosis

Which is an example of passive immunity?
People being vaccinated against disease.
people receiving antibodies from their mothers before birth.
People taking vitamins to boost their immune system.
People producing antibodies against previous diseases.
This type of immunity occurs when people develop their own antibodies:
Passive
Active
Physical
Chemical

Natural passive immunity. (a) is the thick yellowish fluid produced by a mother's breasts for the first four or five days after birth, contains a type of antibody known as IgA.
How do we call the cancers of stem cells in the bone marrow?
Most of the clones of B lymphocytes develop into short-lived (a) cells that produce large quantities of specific antibody
(a) was the first infectious disease of humans to have been eradicated via vaccination
Which of the following is/are functions of antibodies?
Preventing viruses from attaching to host cells
Agglutinating pathogens
Cell lysis
Marking pathogens for faster phagocytosis
Neutralising toxins produced by pathogens
Which of the following are the function of lymph node?
Produces lymphocyte
Stores lymphocyte and macrophages
Filters the lymph
Transport lipid
Remove waste products
