Introduction:
T lymphocyteor T-cell is (white blood cellsubtype) a form of lymphocyte whichdoes a central part in (cell-mediated) immunity. Due to the existence of T-cell receptor on the surface of cell these cells can be differentiated from other lymphocytes likenatural killer cells and B cells.

Answer to Problem 1Q
Correct answer:
The correct answer is option (c) bone marrow→thymus → lymph nodes.
Explanation of Solution
Explanation/justification for the correct answer:
Option (c) bone marrow → thymus → lymph nodes. The development of T-cells takes place in the bone marrow from theHematopoietic Stem Cells but commonly their differentiation happens in the thymus. These cells enter the cortexregion of thymus and they migrate to thymic medulla for further differentiation. Mature T-cells (at the thymic medulla) are then liberated into the peripheral circulation. So, the correct answer is option (c).
Explanation for incorrect answer:
Option (a) Thymus → bone marrow → spleen. Development of T-cells takes place from bone marrow region to thymus and is completed in lymph nodes and no spleen is involved. So, this is an incorrect option.
Option (b) Thymus → bone marrow → thymus. The bone marrow is the initial tissue in which the developmental pathway of T cells begins. So, this is an incorrect answer.
Option (d) Lymph nodes → thymus → spleen. Lymph nodes is the final stage in the developmental pathway of T cells. So, this is an incorrect answer.
Option (e) Bone marrow → lymph nodes → thymus. The option shows the starting point of pathway of T-cells development. So, this is an incorrect answer.
Hence, in the bone marrow T-cells initiate and in thymus these mature and differentiate into different subtypes. The correct answer is option (c) bone marrow → thymus → lymph nodes.

- We will be starting a group project next week where you and your group will research and ultimately present on a current research article related to the biology of a pathogen that infects humans. The article could be about the pathogen itself, the disease process related to the pathogen, the immune response to the pathogen, vaccines or treatments that affect the pathogen, or other biology-related study about the pathogen. I recommend that you choose a pathogen that is currently interesting to researchers, so that you will be able to find plenty of articles about it. Avoid choosing a historical disease that no longer circulates. List 3 possible pathogens or diseases that you might want to do for your group project.arrow_forwardnot use ai pleasearrow_forwardDNK dagi nukleotidlar va undan sintezlangan oqsildagi peptid boglar farqi 901 taga teng bo'lib undagi A jami H boglardan 6,5 marta kam bo'lsa DNK dagi jami H bog‘lar sonini topingarrow_forward
- One of the ways for a cell to generate ATP is through the oxidative phosphorylation. In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules. If a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardIf a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardHow do i know which way the arrows go?arrow_forward
