Algebraic Look at the Result of Demographic Changes Under a Pay-as-You-Go system
A) Please explain the following formula
t=(B/W)*(R/L)
t = B/W × R/L = the average replacement rate × the dependency
ratio
t = total benefits paid
B = the average benefit
R = the number of recipients
W = taxable wages
L = the number of workers

1. Understand the process of vaporization and how it changes with temperature, surface area, and the degree of intermolecular forces.
2. Understand that molecules or atoms have a distribution of thermal energies that changes as a function of temperature.
3.Know that the heat of vaporization, DHvap, is a quantitative measure for the process of vaporization.
4. Calculate and interconvert mass, moles, and energy using the heat of vaporization.
5 Know and understand how vapor pressure and dynamic equilibrium dictate vaporization and condensation.
6 Know that the vapor pressure of a liquid depends on temperature and that the boiling point of a liquid depends on the external pressure.
7 Use the Clausius-Clapeyron equation to relate temperature and vapor pressure.
8. Define critical temperature and critical pressure.

You just discovered, for the first time, that LTP causes learning. Describe the molecular changes involved in LTP. The answer should include: how AMPA and NMDA receptors are different, why this matters, how a particular protein kinase is activated, two important ways this protein kinase contributes to LTP, how a particular transcription factor is activated, how the transcription factor contributes to LTP, how retrograde messengers contribute.

1. Two reactions involving L-amino acids and the values of their respective free-energy changes are as follows:
Glutamate + pyruvate « a-ketoglutarate + alanine
DG°‘ = -2.4 kcal/mol
Glutamate + oxaloacetate « a-ketoglutarate + aspartate
DG°‘ = -11.5 kcal/mol
a) Write the overall reaction for production of alanine and oxaloacetate from aspartate and pyruvate.
b) Show that under standard conditions the net formation of alanine and oxaloacetate from aspartate and pyruvate is thermodynamically unfavorable.
c) Suppose that at 25 °C, the molar concentrations of reactants and products are as follows:
[pyruvate] = [aspartate] = 10 -2 M
[alanine] = 10-4 M
[oxaloacetate] = 10-5 M
Is the spontaneous synthesis of alanine and oxaloacetate possible under these conditions?
