Mouse One has a defect that prevents T lymphocytes from maturing. Mouse Two has a defect that prevents complete thymus development. Neither mouse has mature T cells. What is one way to induce the development of mature T cells in Mouse One?
Answer
Introduce bone-marrow stem cells from Mouse Two into Mouse One
Inject antibodies against defective T cells into Mouse One
Graft thymus from Mouse Two into Mouse One
Inject antibody against CD4 in Mouse One

Question 3
Question
[blank_start]Bone Marrow[blank_end]-location hematopoietic cell division + B cell development
[blank_start]Thymus[blank_end]- Location of T cell development
[blank_start]Lymph nodes[blank_end]- filter blood; trap pathogens; activate antibody production
[blank_start]Spleen[blank_end]- Filter blood; store and filter platelets; store immune cells
[blank_start]Tonsils[blank_end]- contain immune cells that activate immune system when they contact pathogens
[blank_start]Bowel[blank_end]- B cells in the lymphatic tissue produce antibodies; microbiome to prevent pathogen colonization
