In Experiment 2, for PTs that were submerged in water for 2 hrs, as the oven temperature increased from 110° C through 140° C, the W/D value:

Varied, but with no general trend.

Which of the following statements comparing the W/D values of the PTs that were submerged in water for 2 hrs with the W/D value of the PTs that were submerged in water for 10 min is supported by the results of Experiment 1 ?

For all the oven temperatures, the W/D value at 2 hr was less than the W/D value at 10 min

For all the oven temperatures, the W/D value at 2 hr was greater than the W/D value at 10 min

For all the oven temperatures, the W/D value at 2 hr was the same as the W/D value at 10 min

For some of the oven temperatures, the W/D value at 2 hr was greater than the W/D value at 10 min. At the other oven temperatures, the W/D value at 2 hr was less than the W/D value at 10 min.

To determine whether the number of calories per gram in the diet of R. rugulosa affects the growth of R. rugulosa, would the farmer more likely have compared the results of Diets 1-5 or the results of Diets 6-10?

Diets 6-10, because those diets varied in the number of calories per gram but not in the percent by mass of protein.

Diets 1-5, because those diets varied in the percent by mass of protein but not in the number of calories per gram.

Diets 1-5, because those diets varied in the number of calories per gram but not in the percent by mass of protein.

Diets 6-10, because those diets varied in the percent by mass of protein but not in the number of calories per gram.

The slots at the bottom of a diffusion well's pipe were designed to allow the passage of:

Soil gas but not soil or water.

Soil and water but not soil gas.

Water but not soil or soil gas.

Soil gas as well as soil and water.

What percent of the CO2 in each soil gas sample was due to bacterial decomposition of organic matter and not due to respiration in plant roots?

Cannot be determined from the given information

Which of the following statements describing how the average water content generally varied over the 140 cm of soil depth is consistent with Figure 3 ?

On October 26 and November 9, the average water content generally decreased with depth, whereas on November 23 and December 7, the average water content generally increased with depth.

On each of the 4 dates, the average water content generally increased with depth

On each of the 4 dates, the average water content generally decreased with depth.

On October 26 and November 9, the average water content generally increased with depth, whereas on November 23 and December 7, the average water content generally decreased with depth.

Suppose that at each of the 5 locations a diffusion well had been positioned at a depth of 145 cm. Based on Figure 2, on November 23, the average CO2 content of the soil gas at that depth would most likely have been determined to be:

between 0.30% by volume and 0.35% by volume.

between 0.35% by volume and 0.40% by volume.

The steel ball required less time to reach terminal speed in which liquid?

Glycerin; the ball took less than 10 msec in glycerin but more than 25 msec in motor oil to reach terminal speed.

Motor oil; the ball took less than 10 msec in motor oil but more than 25 msec in glycerin to reach terminal speed.

Motor oil; the ball took more than 25 msec in motor oil but less than 10 msec in glycerin to reach terminal speed.

Glycerin; the ball took more than 25 msec in glycerin but less than 10 msec in motor oil to reach terminal speed.

According to Figures 1 and 2, the steel ball's terminal speed was greater in which liquid?

Motor oil; the terminal speed was about 48 mm/sec in motor oil and about 10.5 mm/sec in glycerin.

Motor oil; the terminal speed was about 240 mm/sec in motor oil and about 210 mm/sec in glycerin.

Glycerin; the terminal speed was about 48 mm/sec in glycerin and about 10.5 mm/sec in motor oil.

Glycerin; the terminal speed was about 240 mm/sec in glycerin and about 210 mm/sec in motor oil.

Based on Figures 1, 2, and 3, is it reasonable to conclude that the drag on the steel ball was directly proportional to the depth of the ball?

No; the depth increased only, whereas the drag increased and then approached a constant value.

Yes; both the depth and the drag increased only.

Yes; both the depth and the drag increased and then gradually approached a constant value.

No; the depth increased and then approached a constant value, whereas the drag increased only.
