Indicate the class I pathway that is the source for each component of UMP and AMP biosynthesis. Indicate the number of times each class I pathway must run to provide the combined synthesis of 1 molecule of UMP and AMP and describe how you arrived at this number. *Consider the glucose-6-phosphate --> ribose-5-phosphate to represent the Pentose phosphate pathway.*

What are the concentrations of hydroxide and hydronium ions in a solution with a ph of 10.2?

How does the viscosity of magma change as magma cools?

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
