(A)Rank the test tubes in order of greatest amount of digestion to least amount of digestion. For each tube, explain why it would have exhibited that level of digestion.
(B)How could the experiment be modified to further test human digestion actions? What variables would you change? What would you keep the same?
(C)In which test tube was the activity most like that of a real human stomach? Explain.
Here is the picture.
. (a) What is the order of magnitude of the number ofmicroorganisms in the human intestinal tract? A typical bacterial length scale is 1026 m. Estimate the intestinal volume and assume 1% of it is occupied by bacteria. (b) Does the number of bacteria suggest whetherthe bacteria are beneficial, dangerous, or neutral forthe human body? What functions could they serve?
