- Drug Concentration When a drug is administered orally, it takes some time before the blood concentration reaches its maximum level. After that time, concentration levels decrease. When 500 milligrams of procainamide is administered orally, one model for a particular patient gives blood concentration C, in milligrams per liter, after t hours as C=2.65(e0.2te2t) What is the maximum blood-level concentration, and when does that level occur?arrow_forwardPopulation Growth There are originally 255 foxes and 104 rabbits on a particular game reserve. The fox population grows at a rate of 33 foxes per year, and the rabbits increase at a rate of 53 rabbits per year. Under these conditions, how long does it take for the number of rabbits to catch up with the number of foxes? How many of each animal will be present at that time?arrow_forwardNutrition A researcher performs an experiment to test a hypothesis that involves the nutrients niacin and retinol.

- Grazing Rabbits and Sheep This is a continuation of Exercise 21. In addition to the kangaroos, the major grazing mammals of Australia include merino sheep and rabbits. For sheep, the functional response is S=2.82.8e0.01V, and for rabbits, it is H=0.20.2e0.008V, Here S and H are the daily intake measured in pounds, and v is the vegetation biomass measured in pounds per acre. a. Find the satiation level for sheep and that for rabbits. b. One concern in the management of rangelands is whether the various species of grazing animals are forced to complete for food. It is thought that competition will not be a problem if the vegetation biomass level provides at least 90 of the satiation level for each species. What biomass level guarantees that competition between sheep and rabbits will not be problem?arrow_forwardNutrition A researcher performs an experiment to test a hypothesis is that involves the nutrients niacin and retinol.
