Question

Dendritic cells:

a. Present antigen to T cells to activate them.
b. Can be found in secondary lymphoid tissues.
c. Use only one type of receptor to recognize pathogens.
d. A & B
e. A & C

Answer 1

Dendritic cells present antigen to T cells to activate them and can be found in secondary lymphoid tissues.

Step-by-step explanation:

Dendritic cells function as antigen-presenting cells (APCs) and play a key role in activating T cells. They can be found in secondary lymphoid tissues such as lymph nodes. Dendritic cells have a complex repertoire of receptors that allow them to recognize a wide range of pathogens and present antigen to T cells, activating the immune response.
