6. Under what conditions—assuming no new epi- demics—could infectious diseases suddenly move to the second, or even first, most common cause of deaths in the United States? 7. Do you think humans will ever win the battle against disease-causing bacteria? Why or why not? Is the use of warlike language to describe the relation- ship between humans and bacteria even accurate? 8. Microbiologists are fond of saying that only a tiny minority of bacteria cause disease. Are there reasons for...

Q2. Nitric oxide, NO, is a covalent compound that serves several important roles in the body. Draw an electron dot representation of the NO molecule, showing a double bond between the atoms. Q3. The covalent compound acetylene, which is the fuel of the oxyacetylene torch used by welders, has the molecular formula C2H2. The covalent compound benzene, a commercial solvent, has the molecular formula C6H6. Each of these covalent compounds contains carbon and hydrogen atoms in a one-to-one ratio. Would...
