Congenital Galactosemia typically appears only in infants because with maturation, most children develop another enzyme capable of metabolizing galactose. Its incidence is about 1 per 18,000 births. If the infant does not receive treatment then there is a 75% chance of death. Thus, in the United States infants are screened for galactosemia. Galactosemia can be confused with lactose intolerance but galactosemia is a considerably more serious condition because consumption of galactose can cause permanent damage to their bodies. What dietary changes should be made?

Consider a four-year project with the following information: initial fixed asset investment = $600,000; straight-line depreciation to zero over the four-year life; zero salvage value; price = $46; variable costs = $36; fixed costs = $275,000; quantity sold = 106,000 units; tax rate = 23 percent.

Explain how different concentrations of calcium would lead to LTP vs. LTD. Be specific in your response, including the enzymes activated by calcium and the downstream changes to the number of receptors embedded in the postsynaptic membrane
