As CO2 concentrations increase in the atmosphere, biologists continue to explore the role of respiration from plants as a small but potentially important contribution beyond fossil fuel combustion. The data in the Table were collected from the leaf of a sagebrush plant from a semiarid ecosystem in Wyoming, enclosed in a chamber that measures the rate of CO2 exchange. The respiration rate is the amount of CO2 in micromoles lost by the leaf per square meter per second, which results in the negative numbers. The temperature values are from the leaves as they are heated or cooled during the measurements.

Observation Temperature (°C) Respiration Rate (μmol/m2/s)
1 25 -2.0
2 30 -2.7
3 35 -4.1
4 40 -5.8
5 20 -1.3
6 15 -1.0
7 10 -0.7

I'm studing Cellular Respiration.  We did a lab.  We had technical difficulties... our CO2 gas sensor wasn't working properly.  So I am curious, what trends SHOULD I have seen.  We compared the CO2 output of bean sprouts vs mealworms.  We tested at both room temp (27 degrees C) vs cold temp (15 degrees C) for both the mealworms and bean sprouts.  I need to know the trends I should have seen, ie. does an animal or plant produces more C02 and why?  Also does the the cool temp make the reduction in CO2 production?  Thank you.
The loss of water from a plant by transpiration cools the leaf. Movement of water in transpiration requires both adhesion to the conducting walls and wood fibers of the plant and cohesion of the molecules to each other. A scientist wanted to increase the rate of transpiration of a crop species to extend its range into warmer climates. The scientist substituted a nonpolar solution with an atomic mass similar to that of water for hydrating the plants. What do you expect the scientist's data will indicate from this experiment? The rate of transpiration will be the same for both water and the nonpolar substance. Transpiration rates will fall to zero as nonpolar compounds do not have the properties necessary for adhesion and cohesion. Transpiration rates will increase as nonpolar compounds undergo adhesion and cohesion with wood fibers more readily than water. The rate of transpiration will be slightly lower with the nonpolar substance as the plant will not have evolved with the nonpolar…
The following data were collected from the light-dark bottle incubation experiment for photosynthesis and respiration measurements of a 2-m deep column of water body. The incubation experiment was conducted during the 6.5-hour period from dawn to noon. Please calculate the net photosynthesis (NP), gross photosynthesis (GP), and respiration (R) per square meter of this body of water during a 24-hour day period. Show your calculation process. bottle Dissolved oxygen concentration (mg/L) initial bottle 4.02 light bottle 6.75 dark bottle 2.98
