A life insurance company invests $7000 in a bank account in order to fund a death benefit of $28 comma 000. Growth in the investment over time can be modeled by the differential equation below, where i is the interest rate and A(t) is the amount invested at time t (in years). Calculate the interest rate that the investment must earn in order for the company to fund the death benefit in 36 years.
dA over dt = Ai

Question 1: At the start of the COVID-19 pandemic, the Canadian (and global) economy suffered quickly from a decline in the volume of trade to China. For example, Air Canada quickly discontinued all direct flights to China following the federal government's advice to avoid non-essential travel.
Using the aggregate supply and demand model (OA-DA), rigorously describe the impact of the shock described above on the initial equilibrium of the Canadian economy.

Drugs may cause side effects because:
Select one:
A. the receptors may be found in more than one location in the body.

C. the drug has been poorly manufactured.
D. Any of the above are possible explanations.

Your book has a wonderful term for the coordinated control of glycolysis and gluconeogenesis: reciprocal.
One is stimulated when the other is suppressed. But not only physiological conditions have such effect -- so do individual compounds found in cells.
A key control point in the pathways are the steps catalyzed by phosphofructokinase (in glycolysis) and fructose-1,6-bisphosphatase (in gluconeogenesis). Let's zero in on this spot.
A. Identify 3 compounds that act reciprocally on these two enzymes (inhibiting one and activating the other).
B. Now, explain why the buildup of each of these, in turn, makes sense physiologically. Why, for instance, does it make sense that AMP activates phosphofructokinase and but inhibits fructose-1,6-bisphosphatase? Answer that and then answer a similar question for the other two effector molecules that you identified in part A.
