Document Summary
An agricultural biologist was evaluating two newly developed varieties of wheat as potential crops. In an experiment, seedlings were germinated on moist paper towels at 20 c for 48 hours. Oxygen consumption of the two-day-old seedlings was measured at different temperatures. The data are shown in the graph below. (a) calculate the rates of oxygen consumption in ml/min for each variety of wheat at 7 c and at 17 c. Note: setup can choose any pair of points for the rise-over-run calculation of rate. The values used in the calculations can be greater or less than those shown in the examples below. Units of ml/min are implied by the question stem and need not be specifically shown. Question 2 (continued) (b) explain the relationship between metabolism and oxygen consumption. Discuss the effect of temperature on metabolism for each variety of seedlings. (4 points maximum)
