Answer:
ONE-CELL-THICK LAYER OF FLATTENED CELLS
Explanation:
The circulatory system is lined by a simple squamous epithelium which is a one cell thick layer of flattened cells. It allows for passage of small molecules through the process of filtration and diffusion, The kind of epithelium is found in areas that require rapid diffusion of substances such as capillaries, alveoli, glomeruli of nephron. This epithelium is one celled to the basal lamina and contains flat cells.

Answer:
B) Coating of microbe to aid phagocyte recognition
Explanation:
Opsonization is the process and mechanism which targets the foreign body and helps in the recognition of the pathogen by the phagocytic cells such as the macrophages and dendritic cell.
The opsonization enhances the process of phagocytosis as the opsonin substances which could be the antibodies, proteins or other molecules which could be easily recognised by the phagocytic cells gets attached to the pathogen.
Thus, Option-B is the correct answer.
Opsonization is the coating of a particle with proteins that facilitate phagocytosis of the particle by tissue macrophages and activated follicular dendritic cells (FDCs) as well as binding by receptors on peripheral blood cells
