Animal Immune System starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Animal Immune System.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
Describe how vaccines work to protect animals from infectious diseases.
Describe the difference between primary and secondary immune responses.
Describe the main difference between humoral and cell-mediated immunity.
Describe the process of inflammation and its purpose in the immune response.
Describe the role of mast cells in the immune system.
Explain how the major histocompatibility complex (MHC) is involved in immune recognition.
A patient is born with a genetic defect that prevents the production of major histocompatibility complex (MHC) molecules. Predict and explain the consequences this would have on their immune system.
A researcher observes that an animal exposed to a particular pathogen for the first time shows a slow and weak immune response, but upon a second exposure, the response is much faster and stronger. Explain the immunological basis for this observation.

Fill in the blank: __________ are signaling proteins released by cells in response to pathogens that help regulate immune responses.
Fill in the blank: __________ immunity is present from birth and provides immediate defense against infection.
Fill in the blank: The complement system is a group of __________ that enhances the ability of antibodies and phagocytic cells to clear pathogens.
Fill in the blank: The main function of neutrophils is to __________ pathogens at sites of infection.
True or False: All animals possess both innate and adaptive immune systems.
True or False: All vertebrates have both B cells and T cells as part of their adaptive immune system.
True or False: Antibodies can only bind to one specific antigen.
True or False: Antigen-presenting cells display fragments of pathogens on their surface to activate T cells.
