What is the difference between b-cell lymphocytes and t-cell lymphocytes?
b cells regulate blood ph, and t cells regulate body temperature.
b cells are produced in the thymus, and t cells are produced in the bone marrow.
b cells engulf bacteria, and t cells carry bacteria to the lymph nodes.
b cells produce antibodies, and t cells destroy infected cells.

The right option is; B cells produce antibodies, and T cells destroy infected cells.

B-cells and T-cells lymphocytes are subtypes of white blood cell that are located in the immune system. The B-cells and T-cells lymphocytes are produced in the bone marrow. B cells lymphocytes fight pathogens such as bacteria in the body by producing proteins known as antibodies. The T cells lymphocytes are of two types which are; helper T-cells, and killer T-cells. Helper T-cells trigger B-cells to produce antibodies, and it also help in the development of killer T cells. Killer T-cells functions by directly destroying cells that have already been infected.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
