Adaptive defenses include both humoral and cellular immunity.
Explanation:
The innate immune response is the non-specific immune response and serves to provide an immediate and general immune response. The adaptive immune responses are the specific immune responses. Adaptive immune responses include cell-mediated immunity and antibody-mediated immunity.
Cell-mediated immunity includes T cells (cytotoxic and helper T cells) while antibody-mediated immunity includes the production of antibodies from B cells. Binding of antigen to B cells is followed by their transformation into plasma cells and produce antibodies. Some of the activated B cells form memory B cells that are responsible for quicker and strong secondary immune responses.
Answer
Option C - Skeletal Muscles
Explanation
Antagonistic pairs are the muscles that are functionally opposite, if one produces flexion, then the other's primary action is an extension. Skeletal muscles work in pairs to move a bone so that the muscles can function properly. They contract the bone making nerves deliver a message to the brain. For example. Biceps and triceps. The lower arm is moved upwards when the biceps muscle contracts and the triceps muscle is relaxed and vice versa.
