Roshanda was curious if students in her class would complete a maze faster if fast-paced music was playing in the background. She randomly assigned each student in her class to one of three groups: fast-paced music, slow-paced music, or no music. She timed each student as they individually completed a maze with their corresponding music (or no music) in the background. Students who worked with the fast-paced music, on average, completed the maze significantly faster than students in the other groups. Can we conclude that the fast-paced music caused her classmates to finish the maze faster? Why?

Consider that bacteria can regulate the fluidity of their membranes by varying the chemistry of their fatty acid tails. To survive during a winter storm with a drastic change in temperature from 35°C to 24°C, what would E. coli do to prevent their membrane from becoming too rigid? They would reduce the proportion of saturated fatty acid residues. They would generate longer hydrocarbon fatty acid chains. They would synthesize more cholesterol to build lipid rafts. They would decrease the composition of double bonds in the residues.

How is isoelectric focusing used to separate two proteins of equivalent molecular mass? Isoelectric focusing is based only on positive charges in which a protein band is formed where pH = pKa. Isoelectric focusing is based on ligand affinity in which a protein band is formed where pH = kDa. Isoelectric focusing is based on overall net charge in which a protein band is formed where pH = pI. Isoelectric focusing is based on subunit composition in which a protein band is formed where pH = Keq. Isoelectric focusing is based on overall shape in which pI of globular proteins < pI of elliptical proteins.

1) Use the standard enthalpy and entropy values provided below to calculate the standard free energy change ($\Delta G^\circ$) for the vaporization of liquid H$_2$O at room temperature (298 K). What does the computed value for $\Delta G^\circ$ say about the spontaneity of this process? 2) Use the same values to calculate the standard enthalpy and entropy values for this process in the reverse direction (condensation of gaseous H$_2$O). What does the computed value for $\Delta G^\circ$ say about the spontaneity of this process? Calculate your answers to 3 significant figures and report your answers with the appropriate units. Show your work, including the original equations. H$_2$O (l) $\rightleftharpoons$ H$_2$O (g) H$_2$O (g) $\Delta H_f^\circ$ (kJ/mol) = -241.82 $S^\circ$ (J/K$\cdot$mol) = 188.8 H$_2$O (l) $\Delta H_f^\circ$ (kJ/mol) = -285.83 $S^\circ$ (J/K$\cdot$mol) = 70.0 $\Delta G^\circ = \Delta H^\circ - T \Delta S^\circ$
