Identify the immune response described as nonspecific or specific.
Specific response creates an immediate response to pathogens that enter the body
Nonspecific response evident by a sneeze, cough, fever, or other physical symptom
Specific response recognizes antigens present on pathogens and attacks the pathogen withantibodies
Specific response builds immunity to specific diseases that had previously entered the body
Nonspecific response does not target specific pathogens.
The answer is A.<span>
The parasite causing malaria will try to reproduce inside normal red blood cells.
In case of having sickle-cell disease, the erythrocyte doesn't have a normal</span> shape <span>(it's more curved) and our immune system thinks that this cell should be eliminated due to the deformity.
Since the erytrocyte is going to be eliminated, the parasites inside will also be. This is a survival advantage, and so this allele tends to increase.
However, the disease only happens in heterozygotic people(</span><span><span>with one abnormal allele while the other is normal)</span> because in this cases the deformity is not so severe to cause anemia.</span>
