- Growth of yeast cells In a controlled laboratory experiment, yeast cells are grown in an automated cell culture system that counts the number P of cells present at hourly intervals. The num- ber after t hours is shown in the accompanying figure. 250 200 150 100 50 0 1 2 3 4 5 6 7 a. Explain what is meant by the derivative P'(5). What are its units? b. Which is larger, P'(2) or P'(3)? Give a reason for your answer. c. The quadratic curve capturing the trend of the data points (see Section 1.4) is given by P(t) = 6.10r2 – 9.28t + 16.43. Find the instantaneous rate of growth when t = 5 hours.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 to t = 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). N= f) 1000- 12 21 The function has been modeled by the function (t) = -t(t - 21)(t + 1). Use this model with six subintervals and their midpoints to estimate the total amount of infection (in (infected cells/mL) - day) needed to develop symptoms of measles.t (infected cells/mL) day Need Help? Read ItHow many years will it take to occupy the computer's hard drive that can store data of 82 gigabytes if you used the keyboard to input data? Assume "standard" 8-hour working days, and that one byte is needed to input one keyboard character, and that you are capable to type 180 characters per minute.
- The water is safe to drink if the number of cells falls below 10 cells/mL. It is 8 a.m. and you have 100,000 cells/mL with D being 15 minutes. You add the bleach to the tank. At what time can you release the water? Log Nt = Log N0 – t/D. D is the time required for a log kill.Although these quantities vary from one type of cell to another, a cell can be 1.9 um in diameter with a cell wall 60 nm thick.If you used only a keyboard to enter data, how many years would it take to fill up the hard drive in your computer that can store 95gigabytes95gigabytes (95×109bytes95×109bytes) of data? Assume "normal" eight-hour working days, and that one byte is required to store one keyboard character, and that you can type 180 characters per minute. Express your answer using two significant figures.
- In a lab experiment, 2100 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 5 hours. How long would it be, to the nearest tenth of an hour, until there are 48400 bacteria present? Answer: Submit Answer attempt i out of 2 NG & 5 6 7 9. Y. * CO %24A certain breed of mouse was introduced onto a small island with an initial population of 350 mice, and scientists estimate that the mouse population is doubling every year (a) Find a function N that models the number of mice after t years M) - 350(2) (b) Estimate the mouse population after 9 years. 1X miceA 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).

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?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? kPaOne mole of atoms consist of 6.02 × 10^23 individual atoms.
