Answer:
Phagolysosomal fusion
Explanation:
Macrophages ingest the bacteria through a process called phagocytosis. The phagosome undergoes a series of acidification steps where it fuses with endosomal compartments and encounters bactericidal and antigen processing molecules. Ultimately, it will fuse with the lysosome (phagolysosomal fusion) where it encounters more acidification, hydrolases and bactericidal molecules which may kill the bacteria.
Answer: Covalent bonds are a convenient way of describing the way that a few negatively charged electrons can fix their average location so as to hold two positively charged nuclei together. Chemists know about covalent bonds, electrons do not. All electrons are constantly in very fast motion, they are all indistinguishable from one another, and we have to think in terms not of the position of each electron specifically, but of the average distribution of electrons in a molecule. "Bonds" and "localized electrons" are a convenient fictional calculus and accounting system that allows chemists to work out the properties of molecules and the mechanisms of chemical reactions.
Think of a baseball team made up of nine identical siblings, who constantly and rapidly change fielding positions. You can still describe the team as having a short stop or a second base man, even though you cannot identify an individual person with any role.
