Answer;
-Endocytosis
Explanation;
-Endocytosis includes; phagocytosis, pinocytosis, and receptor mediated: Endocytosis brings substances into the cell, plasma membrane surrounds the substances to be taken in, encloses them in a membrane-bound sac (vesicle) and brings them into the cell
-Phagocytosis: endocytosis of large solid particles (“cell eating”)
-Pinocytosis: endocytosis of extracellular fluid that contains dissolved solutes (“cell drinking”)
-Receptor-mediated: highly selective, ligands bind to specific receptor proteins on the plasma membrane and are then taken into the cell
-Exocytosis: the reverse of endocytosis: substances are removed from the cell; vesicles fuse with plasma membrane and release their contents into the extracellular fluid; important in nerve cells to release neurotransmitter and secretory cells to release cell products (ex. digestive enzymes, protein hormones).
Explanation:
Immunofluorescence or immunoperoxidase assays are commonly used to detect whether a virus is present in a tissue sample. These tests are based on the principle that if the tissue is infected with a virus, an antibody specific to that virus will be able to bind to it.

Which of what? What’s the rest
Answer:
Clostridium tetani
Explanation:
Clostridium tetani causes tetanus, a disease that classically follows injury to the body. Clostridium tetani spores, which are commonly in soil and animal faeces are deposited in the wound and germinate in anaerobic condition. It releases toxins which are tetanospasmin and tetanolysin. Tetanospasmin is responsible for sustained contraction while tetanolysin is responsible for hemolysis of blood cells which is commonly associated with clostridium tetani.
