(a) About how many microorganisms are found in the human intestinal tract? (A typical bacterial length scale is one micron = 106 m. Estimate the intestinal volume and assume bacteria occupy one hundredth of it.) (b) Discuss your answer to part (a). Are these bacteria beneficial, dangerous, or neutral? What functions could they serve?
A new drug is metabolized by healthy aduits at a rate of 25% each hour. After 2.5 hours, a patient had 100 mg of the drug in their body. How much of the drug were they given 2.5 hours ago? You can use the formula: R=Ix0.75 R= amount remaining 1- initial amount t- time Round your answer to one significant digit. Do not include the unit milligrams.
The concentration of a cœrtain drug in the bloodstream t minutes after swallo wing a pill containing the drug can be approximated using the equation C(t) = (2t + 1) –1/2, where C(t) is the concentration in arbitrary units and t is in minutes. Find the rate of change of concentration with respect to time att= 12 minutes.

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.)
Your calculated density of aluminum is d = 2.7 g/cm³. The accepted value of the aluminum density is 2.70 g/cm³. The percent error (follow significant figures rules) is: Just put the number, no need for the % sign
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?

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?
