Bacteria grown in a lab experience what is called an 'exponential phase' of population growth. suppose that, during this phase, a colony of mycobacterium tuberculosis you are growing has a per capita growth rate, r, of 0.063 per hour. if the size of your colony at the start of the exponential phase is 0.25 billion cells, then approximately how large will it be in 48 hours?

The textbook defines ethics as “the principles of conduct governing an individual or a group,” and specifically as the standards one uses to decide what their conduct should be. to what extent do you believe that what happened at bp (british petrolium) is as much a breakdown in the company’s ethical systems as it is in its safety systems, and how would you defend your conclusion?

Six years ago, an 80-kw diesel electric set cost $160,000. the cost index for this class of equipment six years ago was 187 and is now 194. the cost-capacity factor is 0.6. the plant engineering staff is considering a 120-kw unit of the same general design to power a small isolated plant. assume we want to add a precompressor, which (when isolated and estimated separately) currently costs $13291. determine the total cost of the 120-kw unit. (hint: skip $ and comma symbols)

One country has a comparative advantage over another country in the production of a good if ithas a curved production possibilities curve and the other country has a linear production possibilities curve.has lower fixed costs than the other country. has a linear production possibilities curve and the other country has a curved production possibilities curve.is a lower opportunity cost producer of the good.
