(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 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.)
