部分真題預(yù)覽：

1）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 20oC for 48 hours. Oxygen consumption of the two-day-old seedlings was measured at different temperatures. The data are shown in the graph below.

TRICHOME DENSITY IN THREE PLANT POPULATIONS(number of trichomes/cm²)

Calculate the rates of oxygen consumption in mL/min for each variety of wheat at 7°C and at 17°C. Show your work (including your setup and calculation).
Explain the relationship between metabolism and oxygen consumption. Discuss the effect of temperature on metabolism for each variety of seedlings.
In a second experiment, variety A seedlings at both temperatures were treated with a chemical that prevents NADH from being oxidized to NAD+. Predict the most likely effect of the chemical on metabolism and oxygen consumption of the treated seedlings. Explain your prediction.
