Immune Quiz 2 Practice

What do viruses need to reproduce?

• they need genetic material
• They need a host cell
• They need  bacteria
• They need insulin

How does HIV cause damage to the body?

• infects nasal tissue,  making it more likely to catch a cold
• infects B cells, making it less likely to develop antibodies
• infects Helper T cells, making it difficult for the immune system to communicate
• infects the nervous tissue, making it hard to sense a stimulus

These cells are responsible for making antibodies

• B Cells
• Killer T Cells
• Helper T Cells
• Macrophages

What do antibodies attach to on the pathogen?

• Anti inflammatory
• Antigens
• Antiseptic
• Antibodies

What is a macrophage?

• It is a cell that traps foreign antigens and then displays them on their cell surfaces in a form that can be recognized by lymphocytes.
• It is a bacterium that causes a chronic, recurrent infection, often of the lungs, but any organ may be infected.
• It is an organ also known as a lymph gland.
• It is a cell that develops in the thymus, located in the upper half of the chest near the heart.

The blue molecule in this image is a(n) _______

• Antibody
• Antigen
• Pathogen
• Blood cell

Which best describes the relationship between antibodies and antigens?

• Antibodies are specific to one antigen
• Antigens are produced in response to antibodies
• One antibody can affect several different antigens
• Immunity develops when an antigen destroys an antibody.

Which of the following antigens would bind to this B cell receptor?

• 
• 
• 
• 

What is the result of this interaction?

• A T-cell is activated

• The virus can't bind to and infect a cell

• A B cell starts making antibodies

• An antigen presenting cell will present its antigen

Which part of an antibody can attach to an antigen?

• A
