B. antigen: stimulates immune system response

C. natural killer cells: innate immune system

D. mucus membranes: innate immune system

E. antibodies: mark pathogens for destruction

F. None of the above (all terms and functions are matched correctly)

4.Fill in the blanks with the most appropriate choice. In humans, the majority of oxygen is moved through the body by binding with ______________ on _________________. The majority of carbon dioxide is moved through the body by forming _______________.

A. red blood cells; plasma

B. hemoglobin; white blood cells; lymphocytes

1, Most RNA viruses are single stranded and replicate in the cytoplasm while most DNA viruses are double stranded and replicate in the nucleus. Briefly explain why this makes sense for each of these 4 characteritics (4 points). Each of the following viruses breaks one of these (e.g. might be double stranded RNA virus). For each of these viruses say which of these it breaks (4points). Bonus points. Describe the major pathology for Molluscipox virus and B19 Parvovirus (2points). Rotavirus...
