Question

Innate immunity differs from adaptive immunity in all of the following EXCEPT:

A. it is more primitive evolutionarily than adaptive.
B. its receptors are not encoded in the germline.
C. it has been selected to identify broad classes of pathogens.
D. it has been selected to target common pathogens.
E. All of the above are accurate statements.

Answer 1

The main difference between innate immunity and adaptive immunity is that the receptors for innate immunity are encoded in the germline, while the receptors for adaptive immunity are not.

Step-by-step explanation:

The main difference between innate immunity and adaptive immunity is that the receptors for innate immunity are encoded in the germline, while the receptors for adaptive immunity are not. This means that the receptors for innate immunity are present on the cell surface even when they are not needed, whereas the receptors for adaptive immunity are produced only in response to specific pathogens.

For example, the innate immune system uses a limited number of receptors that can recognize a wide variety of pathogens, while the adaptive immune system produces large numbers of highly specific receptors that can each recognize a particular pathogen.

So, the correct answer is B. its receptors are not encoded in the germline.
