3. Among the four major classes of biological molecules (sugars, lipids, amino acids, nucleotides), which do you think has the lowest turnover (replacement) in a cell? Why? The bomb pulse is the doubling of C14 carbon in the atmosphere as the result of above ground nuclear testing by the US, Russia, and other major world powers during the 1950s and 1960s. The amount of C14 carbon has slowly declined after the half of above ground nuclear testing in 1965 following the signing of the Limited Test Ban Treaty. The amount C14 in trees is directly proportional to the amount of C14 carbon present in the atmosphere B C 900 830- 700- 600- 500- 400- 300- 200- 100- 0 1950 1960 1970 1980 1990 2000 4. Based on your answer to questions 1.2 and 1.3 and the known rate of decay of C14 in the atmosphere in the figure above, propose a way by which you could measure the relative age of a cell. Assume that the amounts of C14 carbon present in a given molecule do not change once the molecule has been formed.

Consider that the current world price for copper ore is $5.20 per pound. Suppose the domestic market for copper ore in Chile is described by the following demand and supply equations, respectively: P=7.00-0.015Q and P=0.6+0.025Q, where P is the price per pound, measured in dollars, and Q is the quantity measured in thousands of pounds per month. Similarly, suppose that the domestic market for copper ore in Japan is described by the following demand and supply equations: P=8.40-0.02Q and P=0.6+0.04Q, where P is the price per pound, measured in dollars, and Q is the quantity measured in thousands of pounds per month. After receiving requests from lobbyists and domestic producers, the government of the importing country imposes a tariff of $0.20 in the market for copper ore. As a result of the government's policy, what is the change in consumers' expenditure in the importing country (report your answer at 2 decimal places)

The production manager on the Ofon Phase 2 offshore platform operated by Total S.A. must purchase specialized environmental equipment or an equivalent service. The first cost is $250,000 with an AOC of $66,000. The manager has let it be known that he does not care about the salvage value because he thinks it will make no difference in the decision-making process. His supervisor estimates the salvage might be as high as $100,000 or as low as $10,000 in 3 years, at which time the equipment will be unnecessary. Alternatively, a subcontractor can provide the service for $160,000 per year. The total offshore project MARR is 12% per year. Determine if the decision to buy the equipment is sensitive to the salvage value. The annual worth of high salvage value is $ The annual worth of low salvage value is $ Decision is sensitive to salvage value.
