Max is bitten by a rattlesnake while on a camping trip. His friends immediately apply ice packs to the bitten area to slow the spread of the protein-based toxin; they then rush him to an emergency facility. Upon doing blood work, it was determined that Max had a bacterial infection from a tick bite resulting in a primary humoral response.  The doctor told Max that he was lucky because the tick could have also caused Lyme's disease, but he had natural active immunity to that microbe. Explain why Max did not also get Lyme's disease. What role did his immune system play in preventing this infectious disease?

Explain antigen-antibody interactions. Using the following diagram, interpret the two types of antibody responses, primary and secondary, to presentation of a specific antigen. In your answer you should refer to the structure and function of the IgM and IgG antibodies. You may use a diagram(s) as part of your explanation. Interpret antigen/antibody interactions with references in Harvard style

"____" Adaptive immune responses are activated independently of the innate immune response. "____  " Activation of complement on the bacterial cell surface also trigger local inflammation. " ____ "

Miya fell in the playground and a splinter got stuck in her arm. Describe in your own words and in detail how Mia's immune system will react to the splinter in her arm. What is this reaction called and what are the immune cells and proteins/molecules involved.

In studies of skin grafts, thymectomized mice (their thymus has been removed) are often used. B cells don’t develop in the thymus, but nonetheless, these mice are often subject to infection.  Why would the removal of the thymus improve the success of skin grafts, but adversely affect immunity?
