Answer:
Explanation:
Lymphocytes are the agranular cells of WBC. These are mainly 2 types - T lymphocyte and B- lymphocytes. Natural killer cells/ NK cells are also another type of lymphocyte. The lymphocytes are present in both blood and lymph. They play are responsible for both innate and adaptive immunity.
The natural killer cells are meant for both innate immunity and adaptive immunity. The T cells and B cells are responsible for adaptive immunity.
The humoral immunity is mediated by B cells while T cells are mediated the cell-mediated immunity. When an antigen enters into the body the B cells get to activate and it becomes effector B cells. These B cells are proliferated by mitosis and produce plasma cells. Plasma cells have antibodies which provide adaptive immunity.
Both the B lymphocytes and T lymphocytes are synthesized in the bone marrow. This process is called hematopoiesis. Then these 2 types of cells are separated and mature in different cells. Therefore, bone marrow is the precursor of B cells and T cells.
B lymphocytes are matured in bursa or MALT cells, while the T lymphocytes are matured in the thymus.
T cells are not the only form of lymphocytes found in lymphoid tissues. The lymphoid tissues are - bone marrow cells, WBC, thymus, spleen, lymph nodes. Macrophages are the larger WBC and one form of monocytes.

You haven't included answer choices, so my answer may not match up with the answers you have to choose from. However, this has to do with the polar reversal theory, which was developed after the discovery of magnetic striations at the bottom of the Marianas Trench. According to this theory, Earth's magnetic poles reverse every 200,000-350,000 years due to the constant recycling of Earth's crust through subduction of tectonic plates.
