Immune System and Antibodies Quiz

What does the immune system store to recognize threats it has encountered before?

• Cellular memory

• Brain memory

• Genetic memory

• Muscle memory

What is the first line of defense against invaders in the body?

• Skin

• Inflammation

• Antibodies

• White blood cells

What is the main role of antibodies in the adaptive immune response?

• To digest invaders

• To create inflammation

• To latch onto specific enemies

• To produce white blood cells

How does the immune system create antibodies for germs it has never encountered?

• By using a fixed set of blueprints

• By using muscle memory

• Through random genetic shuffling

• By copying antibodies from other people

What is the purpose of the random DNA letters inserted between genes in B-cells?

• To increase the variety of possible antibodies

• To create a fixed antibody shape

• To eliminate weak antibodies

• To reduce the number of antibody combinations

What is the role of B-cells after they lock onto their match?

• They turn into white blood cells

• They destroy themselves

• They clone themselves and produce antibodies

• They become inactive

What do vaccines do to help the immune system?

• They eliminate the need for antibodies

• They create a memory of a germ without causing illness

• They directly attack viruses

• They replace white blood cells

How long can the memory created by vaccines last?

• A few months

• A lifetime

• A few days

• A few years

What challenge do scientists face in creating universal immunity?

• Germs do not mutate

• Antibodies are too weak

• Germs constantly evolve and mutate

• Vaccines are ineffective

What is a potential benefit of finding rare antibodies that bind to every version of a virus?

• They can lead to a universal flu treatment

• They can stop all mutations

• They can replace all vaccines

• They can eliminate the need for an immune system
