The answer is: Hydrogen bonds with the polar end of the phospholipid molecule.

Explanation for each option:

  1. Covalent bonds with the nonpolar end of the phospholipid molecule: This is incorrect. Covalent bonds involve the sharing of electron pairs between atoms, which is not the typical interaction between water molecules and the nonpolar end of a phospholipid.

  2. Hydrogen bonds with the nonpolar end of the phospholipid molecule: This is incorrect. The nonpolar end of a phospholipid is hydrophobic and does not form hydrogen bonds with water molecules.

  3. Hydrogen bonds with the polar end of the phospholipid molecule: This is correct. The polar end of a phospholipid is hydrophilic and can form hydrogen bonds with water molecules due to the attraction between the polar head groups and the polar water molecules.

  4. Polar bonds with the nonpolar end of the phospholipid molecule: This is incorrect. Polar bonds typically refer to bonds between atoms with different electronegativities, and the nonpolar end of a phospholipid does not engage in such interactions with water.

  5. Polar bonds with the polar end of the phospholipid molecule: This is incorrect. While the polar end of the phospholipid can interact with water, the specific interaction is through hydrogen bonds rather than a general term like "polar bonds."

Summary: Water molecules form hydrogen bonds with the polar end of the phospholipid molecule due to the hydrophilic nature of the polar head groups.

The tropopause is a defined boundary that separates the troposphere (below) from the stratosphere (above). At the tropopause, the temperature trend changes from decreasing significantly as altitude increases to nearly constant (isothermal) or begins to increase with altitude (called a temperature inversion) in the lower stratosphere. Based on the temperature pattern you plotted, the tropopause in the Salt Lake City example sounding was located at a pressure level above mb . a. 700 b. 500 c. 300 d. 200 The tropopause over Salt Lake City occurred at an altitude nearest km above sea level, according to the altitude scale on the Stüve diagram. This can be confirmed from the observed altitude reported in Table 2B-1. a. 6 b. 9 c. 12 d. 16 This Salt Lake City tropopause was altitude compared to the altitude of the tropopause in the Standard Atmosphere. The Standard Atmosphere tropopause occurs at 11 km . a. at a lower b. about the same c. at a higher Since the weight of the overlying air determines air pressure, this means about half of the weight of air over Salt Lake City's atmosphere was above 500 mb and half below. In Table 2B-2, the pressure of 500 mb occurred at an altitude of m. a. 2943 b. 5390
