(1) A typical bacterium has a mass of 1 picogram (1 × 10-¹2 gram). Calculate the mass of a mole
(or 1 [mol]) of bacteria. Compare this with the mass of a car.
If the density (mass divided by volume) of the wall material is the same as that of pure water, what is the mass (in mgmg) of the cell wall, assuming the cell to be spherical and the wall to be a very thin spherical shell?
A typical adult human lung contains about 300 million tiny cavities called alveoli. Estimate the average diameter of a single alveolus.

- 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.)arrow_forward(II) Use Table 1–3 to estimate the total number of protons or neutrons in (a) a bacterium, (b) a DNA molecule, (c) the human body, (d) our Galaxy.arrow_forward(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.

- Assuming the human body is made primarily of water, estimate the volume of a person.arrow_forward[#142] How many cells are you? How many cells in a human? Assume that cells have a typical size of about 10 µm (1µm = 10-6 m) in all directions. And that we are the same density as water, and are made completely of cells (both exaggerations, of course, but fine for an order of magnitude estimate). Hints: What is the volume of a cell? What is the volume of a human? How can these quantities be related to give the number of cells in your body? The shape of the cell is not important in this rough estimate: for instance, the difference in volume fraction between say cubes and close packed spheres is only 26%. Format: When you enter your answer, enter it as a power of 10. For example: for 100000, enter "10^5". We'll use this notation later, too.arrow_forwardBacteria and other prokaryotes are found deep underground, in water, and in the air.

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?
