45) Following a hike in the woods, you encounter an angry rattlesnake as you are approaching your car. Not knowing it was there, you stepped on its tail and it proceeded to bite you. Luckily you were close to the hospital and a fellow hiker drove you there. Once there, you were given an antivenom serum; which the doctor explained as an immunoglobulin made by sheep but injected into human snake bite victims. What type of process is this describing? A) Naturally acquired passive immunity B) Naturally acquired active immunity C) Artificially acquired passive immunity D) Artificially acquired active immunity

A patient has many allergic reactions. As part of the treatmentscheme, doctors try to identify the allergen that stimulates theimmune system’s response. A series of solutions, each containing anallergen that commonly causes a reaction, is composed. Each solution is injected into the skin at different locations on the patient’sback. The following results are obtained: (a) At one location, theinjection site becomes red and swollen within a few minutes;(b) at another injection site, swelling and redness appear 2 dayslater; and (c) no redness or swelling develops at the other sites.Explain what happened for each observation by describing whatpart of the immune system was involved and what caused the redness and swelling.
(66)A laboratory animal is scheduled to be immunized by receiving weekly injections of antigen X. Analysis of serum drawn 2 days after the last immunization would show antibodies to antigen X to be primarily of which of the following classes? (A) IgA (B) IgD (C) IgE (D)IgG (E)IgM

You are studying SARS-COV2. You identify a viral protein that results in the decrease of MHC class I, a cell surface receptor, on the cell surface. You are trying to determine the mechanism for how the virus is decreasing cell surface MHC I. You decide to do an experiment to determine whether the receptor is making it all of the way through the secretory pathway. You take two samples of cells. 1. Uninfected 2. Infected with SARS-CoV2 You treat them with EndoH and analyze MHC I on a western blot and get the following results: 1. Uninfected cells - 50% of protein is endo H sensitive and 50% is Endo H resistant 2. SARS-COV2 infected cells - 100% of protein is Endo H sensitive How would you best interpret these results? Is MHC I going all the way through the secretory pathway in infected cells? A. No, MHC I is not going all the way through the secretory pathway. 100% of the protein is EndoH sensitive in infected cells, this means that the virus is somehow inhibiting the protein from making…
A viral pathogen "V" has a highly immunogenic and conserved protein "P". Injecting "P" into an individual's body can provide them with both humoral and cellular immunity against "V". There are two types of vaccines in the market against "V". One pf these contains heat-killed "V". The other one contains only "P", Which one would you prefer? Why?
Herd immunity means that the entire population (not just those who are vaccinated) are protected from a disease. What is one way that herd immunity protects an unvaccinated person (such as an infant who is too young to be vaccinated or a person who is immunocompromised)?
