Suppose the rate of growth of crops in each of the vertical farming chambers is determined by either weekly average air temperature, weekly average humidity, or both. If the growth rate in Chamber 2 greatly exceeds the growth rate of Chambers 1 and 3, which of the following conclusions would be justified? Relative to the temperatures and humidity levels in the experiment:

• A. high weekly average air temperature or high weekly average humidity is ideal for plant life growth rate.

• B. medium weekly average air temperature or medium weekly average humidity is ideal for plant life growth rate.

• C. low weekly average air temperature or low weekly average humidity is ideal for plant life growth rate.

• all of the above conclusions can be justified.

Do the results from Experiment 1 support the claim that photovoltaic cells capturing different frequency ranges function at varying efficiencies with changes in temperature?

• Yes, because as temperature increases, so does efficiency.

• Yes, because as temperature increases, efficiency decreases.

• No, because there is no uniform change in efficiency as related to temperature.

• No, because all photovoltaic cells function at the same efficiency regardless of frequency.

Based on the results from Experiment 1, photovoltaic cells capturing which frequency range of light would function best in environments that keep the cell temperatures at roughly 29°C?

• Frequency 1

• Frequency 2

• Frequency 3

• All frequency ranges will function the same.

One of the scientists suggests that he can build a cooling system for the theoretical photovoltaic cells in Experiment 2, which will keep the cells 1°C cooler than normal but decrease their efficiency by 1%. The theoretical photovoltaic cells capturing which frequency ranges, if any, would benefit from this cooling system?

• Frequency Ranges 1 and 2

• Frequency Ranges 1 and 3

• Frequency Ranges 2 and 3

• None of the theoretical photovoltaic cells would benefit.
