Question

40-41 20 at 22 c 02 at 120 to measure cellular respiration in the graph, answer the following questions accompanying graph shows results from an experiment done eermsinuting and songerminating com seeds. Oe the basis of Which of the following is a true statement based on the data? A. The amount of oxygen consumed by germinating B. The rate of oxygen consumption is the same in 40. The both germinating and nongerminating com com at 22oC is approximately twice the amount of oxygen consumed by germinating corn at during the initial time period from 0 to 5 minutes. The rate of oxygen consumption is higher for 2oC C. The rate of oxygen conumption in the E. If the experiment were run for 30 minutes, the What is the rate of oxygen consumption in germinating corn at 12oC D. xerminating corn at 120C 10 minutes is 0.4 mlnongerminating corm at 12oC than at 22oc. rate of oxygen consumption would decrease 4I. (study the graph to answer the question.) A. 0.08 mlimin C 08 m/min B. 0.04 ml/min. D. 0.4 ml/min 42. (Study the ruh to anwer the question Which of the following conclusions is supported by the data? The rate of respiration is higher in nongerminating seeds than in germinating seeds. A. B. The rate of respiration in the germinating seeds would have been higher if the experiment were conducted in sunlight The amount of oxygen consumed could be Nongerminating peas are not alive, and show no difference in rate of respriation at different temperatures The rate of respiration increases as teh temperature increases in both germinating and nongerminating seeds. C. D. E. increased if pea seeds were substituted for corn seeds Page 7v1 14

Answer 1

Ans 40: the amount of oxygen consumed by germinating corn at 22oC is approximately twice the amuont of oxygen consumed by germinating corn at 12oC.

Ans 41: 0.04ml/min

Ans 42: the rate of respiration increases as temperature increases in both germinating and non germinating seeds
