Answer to Question 1

ANS: B
Nonhydroxide bases. Ammonia and carbonates are good examples of nonhydroxide bases. Pro-teins, with their amino groups, also can serve as nonhydroxide bases.

Answer to Question 2

ANS: C
Protein bases. Proteins are composed of amino acids bound together by peptide links. Physiolog-ic reactions in the body occur in a mildly alkaline environment. This allows proteins to act as H+ receptors, or bases. Cellular and blood proteins acting as bases are transcribed as prot. The imid-azole group of the amino acid histidine is an example of an H+ acceptor on a protein molecule (Figure 12-4). The ability of proteins to accept hydrogen ions limits H+ activity in solution, which is called buffering. The ability of hemoglobin to accept (i.e., buffer) H+ ions depends on its oxy-genation state. Deoxygenated (reduced) hemoglobin is a stronger base (i.e., a better H+ acceptor) than oxygenated hemoglobin.

There used to be a metric calendar, as well as metric clocks. The metric calendar, or "French Republican Calendar" divided the year into 12 months, but each month was divided into three 10-day weeks. Each day had 10 decimal hours. Each hour had 100 decimal minutes. Due to lack of popularity, the metric clocks and calendars were ended in 1795, three years after they had been first marketed.
