1. antibodies antigen defence host Lymphocytes nicotine non-specific nucleic phagocytosis Plants protein resin specific tannins Viruses white exhibit living and non-living characteristics and can only reproduce within the living cells of another organism. 2. A virus consists of one type of antibodies antigen defence host Lymphocytes nicotine non-specific nucleic phagocytosis Plants protein resin specific tannins Viruses white acid surrounded by a coat of antibodies antigen defence host Lymphocytes nicotine non-specific nucleic phagocytosis Plants protein resin specific tannins Viruses white . 3. Once inside a host cell, the virus alters the antibodies antigen defence host Lymphocytes nicotine non-specific nucleic phagocytosis Plants protein resin specific tannins Viruses white cell’s metabolism to produce many identical copies of itself. 4. The two main antibodies antigen defence host Lymphocytes nicotine non-specific nucleic phagocytosis Plants protein resin specific tannins Viruses white mechanisms employed by the human body depend on the activities of antibodies antigen defence host Lymphocytes nicotine non-specific nucleic phagocytosis Plants protein resin specific tannins Viruses white blood cells. 5. Phagocytes engulf and destroy microbes by antibodies antigen defence host Lymphocytes nicotine non-specific nucleic phagocytosis Plants protein resin specific tannins Viruses white using lysosomes. This is a antibodies antigen defence host Lymphocytes nicotine non-specific nucleic phagocytosis Plants protein resin specific tannins Viruses white immune response. 6. antibodies antigen defence host Lymphocytes nicotine non-specific nucleic phagocytosis Plants protein resin specific tannins Viruses white recognise antigens on the surface of a microbe and produce antibodies antigen defence host Lymphocytes nicotine non-specific nucleic phagocytosis Plants protein resin specific tannins Viruses white . These possess receptors sites which bind to one particular type of antibodies antigen defence host Lymphocytes nicotine non-specific nucleic phagocytosis Plants protein resin specific tannins Viruses white rendering it harmless. This is a antibodies antigen defence host Lymphocytes nicotine non-specific nucleic phagocytosis Plants protein resin specific tannins Viruses white immune response. 7. antibodies antigen defence host Lymphocytes nicotine non-specific nucleic phagocytosis Plants protein resin specific tannins Viruses white do not make antibodies. They defend themselves against invasion by producing compounds such as antibodies antigen defence host Lymphocytes nicotine non-specific nucleic phagocytosis Plants protein resin specific tannins Viruses white , cyanide and antibodies antigen defence host Lymphocytes nicotine non-specific nucleic phagocytosis Plants protein resin specific tannins Viruses white . 8. Some plants can isolate an area of injury by secreting sticky antibodies antigen defence host Lymphocytes nicotine non-specific nucleic phagocytosis Plants protein resin specific tannins Viruses white .
