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.
Answer:
B cells and T cells are the white blood cells of the immune system that are responsible for adaptive immune response in an organism. Both the cells are made in the bone marrow.Explanation:
B cells produce antibodies, and T cells destroy infected cells. So, the correct option is D.
What are B cells and T cells?The two primary categories of lymphocytes are T cells and B cells. Antibody molecules made by B cells can attach to and kill invasive viruses and bacteria. T cells are the immune system's first line of defence against foreign invaders. They also create cytokines, that are biological agents that aid in the activation of other immune system components.
T cells can eliminate malignant or contaminated cells. Moreover, they control overall immune response by assisting B cells in eradicating foreign infections. Antibodies are made by B cells. An antibody is a class of protein produced by B lymphocytes, sometimes known as B cells.
Therefore, the correct option is D.

Which organism will most likely become fossilized from being buried in sediment? Insect , snail, jellyfish or a worm
Answer:
When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts.
