QID 212618 (Type "212618" in App Search)
A researcher is studying the effects of various substances on mature B-cells. She observes that while most substances are only able to promote the production of antibodies when the B-cells are co-cultured with T-cells, a small subset of substances are able to trigger antibody production even in the absence of T-cells. She decides to test these substances that stimulate B-cells alone by injecting them into model organisms. She then analyzes the characteristics of the response that is triggered by these substances. Which of the following correctly describes how the immune response triggered by the B-cell-alone-substances compares with that triggered by substances that also require T-cells?
