T cells:Group of answer choicesspend time developing in the thymus.are responsible for cell-mediated immunity.respond to antigens by releasing antibodies.spend time developing in the thymus and are responsible for cell-mediated immunity.
Solution
The correct answer is "T cells spend time developing in the thymus and are responsible for cell-mediated immunity."
Here's why:
-
T cells, also known as T lymphocytes, are a type of white blood cell that plays a crucial role in the immune response.
-
The 'T' in T cells stands for thymus, which is the gland where these cells mature. This is why the statement "T cells spend time developing in the thymus" is correct.
-
T cells are responsible for cell-mediated immunity, which is the immune response that involves the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen. This is why the statement "T cells are responsible for cell-mediated immunity" is correct.
-
T cells do not respond to antigens by releasing antibodies. This is a function of B cells, another type of white blood cell. Therefore, the statement "T cells respond to antigens by releasing antibodies" is incorrect.
So, combining the correct statements, we get "T cells spend time developing in the thymus and are responsible for cell-mediated immunity."
