Which of the following statements about the tundra is not true? a. tundra means “treeless land.” b. plants and animals in the tundra have adapted to the extreme climate. c. temperatures in the tundra range from extreme highs to extreme lows. d. the alpine tundra can be found on mountaintops.

C. Temperatures in the tundra range from extreme highs to extreme lows.

During the winter a Tundra can reach temperatures of -50 degrees. In the summer a Tundra usually reaches a max of only 45 degrees. A Tundra is pretty much cold during the summer and freezing during the winter. So, therefore, the answer must be C because a Tundra never gets extreme highs in temperature. 

Hope this helped. Have a great day! :)

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature
