In a person infected with measles, the virus level N (measured in number of infected cells per ml of blood plasma) reaches a peak density at about t = 12 days (when a rash appears) and then decreases fairly rapidly as a result of immune response. The area under the graph of N(t), the t-axis, and the lines t = 0 tot = 12, (as shown in the figure) is equal to the total amount of infection needed to develop symptoms (measured in density of infected cells x time).

A population of E. coli bacteria grows exponentially with time. You believe that the mean time between divisions is t, = 26 min, and that cell death occurs on average after tm = 200 hr. The population starts with 1000 cells. Complete parts (a) through (c). (a) Use the equation N(t) = N, e0-m)t to predict how many cells are present after 3 hours. The number of cells present after 3 hours is. (Do not round until the final answer. Then round to the nearest integer as needed.)
The mass of a substance, which follows a continuous exponential growth model, is being studied in a lab. The doubling time for this substance was observed to be 18 hours. There were 95.1 mg of the substance present at the beginning of the study. (a) Let i be the time (in hours) since the beginning of the study, and let y be the amount of the substance at time 1. Write a formula relating y to t. Use exact expressions to fill in the missing parts of the formula. Do not use approximations. アミ (b) How much will be present in 16 hours? Do not round any intermediate computations, and round your answer to the nearest tenth, mg olo
The rate of change of atmospheric pressure P with respect to altitude h is proportional to P, provided that the temperature is constant. At a specific temperature the pressure is 102.3 kPa at sea level and 88 kPa at h = 1,000 m. (Round your answers to one decimal place.) (a) What is the pressure (in kPa) at an altitude of 3,500 m? kPa (b) What is the pressure (in kPa) at the top of a mountain that is 6,365 m high? kPa
(a) What is the order of magnitude of the number of micro organisms in the human intestinal tract? A typical bacterial length scale is 10-6 m. Estimate the intestinal volume and assume 1% of it is occupied by bacteria. (b) Does the number of bacteria suggest whether the bacteria are beneficial, dangerous, or neutral for the human body? What functions could they serve?
(a) what is the average rate of change of the number of bacteria in the culture between 1 and 3 hours after the measurements begin? (b) because the average rate of science is _ the bacterial population is decreasing at an average rate of _ bacteria per hour between one and three hours after management begins?
(a) Calculate the number of cells in a hummingbird assuming the mass of an average cell is ten times the mass of a bacterium. (b) Making the same assumption, how many cells are there in a human?
The volume of air we breathe in is about 10% of lung capacity perbreath. If the level of PM2.5 is constant at 40 μg/m3 over the wholeyear, how many grams of dust would you inhale in total in one year,assuming that the dust particles in every breath are all collected inyour lung?
the mass m, is given the equation m=i[0.69]t. i is the intitial dose and t is the number of hours since the dose. Suppose the patient is given inital dose of 200mg. When will the amount of ibuprofen in the bloodstream be reduced by a factor of one half. round your answer to the nearest tenth of an hour
A patient is diagnosed to have Po cancer cells at time t = 0 and these cells grow subsequently according to P = −aP(M – P) where P(t) is the number of the cells at time t while a and M are two given positive constants. The patient will die when the number of bugs approaches infinity. Consider the case Po > M for the prognosis of the patient, i.e., find the time the patient has left to live.
patient is to be given an intitial dose of 23.4 mL of a medication and 1.2 mL/h thereafter for 8.5h. write an equation that relates the volume of medication administered as a function of time
(a) Suppose that a person has an average heart rate of 72.0 beats/min. How many beats does he or she have in 2.0 years? (b) In 2.00 years? (c) In 2.000 years?
