Answer 1

Question No.1

Answer :- The body's nonspecific defenses are innate and it is the first line of defense against pathogens by functioning in the same way against every pathogen Like virus , bacteria or protozoan.

Answer :- Natural killer cells function as the first line of defense which Can distinguish between infected and uninfected host cells , target and kill infected cells.

Example - IFN-γ and TNF-α which  stimulate maturation of dendritic cells which are the main coordinators of both innate and adaptive immunity.

Question No.3

Answer : Interferons leave the infected cell and bind to another uninfected cells membrane or nuclear membrane receptors and Telling them to synthesize antiviral proteins (AVPs) which kill viruses and protect the body from severe infection...

Question No.4

Answer : adaptive immunity is vey specific which produces memory cells, and it induces a response that provides long-lasting protection from pathogens and the cell involved in T and B lymphocytes... Thanks dear
