Which of the following statements is true of acquired immunity? It does not involve experience and its forms include phagocytosis and inflammation. Acquired immune responses take longer to initiate than natural immune responses. An effective immune response occurs even before prior exposure to a particular antigen. It consists of a number of inborn processes that help remove foreign substances from the body.

The innate immunity system clears about what percentage of the invading pathogens? 0.90% 50% 0 10% 0 1%

Which of these is an incorrect description of either the adaptive or innate immune responses?   Innate immunity involves both surface barriers and internal defenses. Only adaptive immunity involves defense against a specific foreign invader. Inflammation is an innate immune response but not an adaptive immune response. Chemicals are involved in adaptive immunity but not innate immunity. Immune system cells play a role in both innate and adaptive immune responses.

Which of the following occurs during an active immunization? A preparation of a specific antigen is provided to a patient to induce immunity by forming effector and memory cells. Effector and memory cells do not form. A preparation of antibodies is provided to an individual who was already exposed to a lethal agent.

Which of the following is true about the adaptive immune system? Check all please. Adaptive immunity develops several days after the initial infection, but eliminate pathogens in a specific manner and is saved as memory to encounter the same reinfection Adaptive immunity is improved with repeated infections with the same pathogen A robust primary adaptive immunity can be generated in the absence of innate immunity Adaptive immune cells are B cells that make antibodies and T cells that eliminate infected cells and make cytokines Dendritic cells present antigens to T cells, whereas macrophages present antigens to B cells.

Which of the following immune responses is NOT considered as the first line of defense or innate immune response? O Inflammation Immunoglobulin O Interferon Natural killer cells

*Passive immunity______. Group of answer choices requires exposure to an antigen may be obtained by taking antibiotics results in the production of memory cells is the result of vaccination All of these are correct *Which of the following is not a characteristic of immediate hypersensitivity? Group of answer choices excessive inflammatory response activation by harmless antigens activation of basophils secretion of lymphokines

What is a lymphocyte central to adaptive immunity that targets infected or cancerous body cells?     Macrophage   Dendritic cell   B cell   T cell

Which of these are the products of the immune response that will stay with the person for  long term immunity?     Memory-T's and circulating antigen     Helper T's and circulating antigen     Memory T's and thymus     Memory-T's and circulating antibody
