Suppose a new crop rotation for Field B included legumes and other deep-rooted and high-residue crops. The SOM of this field will most likely change in which of the following ways? The SOM will:

• decrease, because soil quality is likely to increase.

• decrease, because soil quality is likely to decrease.

• increase, because soil quality is likely to increase.

• increase, because soil quality is likely to decrease.

• Yes; based on SOM, Field B had a soil quality rating of fair and Field A had a soil quality rating of poor.

• Yes; based on SOM, Field B had a soil quality rating of excellent and Field A had a soil quality rating of fair.

• No; based on SOM, Field B had a soil quality rating of poor and Field A had a soil quality rating of fair.

• No; based on SOM, Field B had a soil quality rating of fair and Field A had a soil quality rating of excellent.

• As soil quality improves, the number of earthworms increases. Students hypothesized that more earthworms would be found in Field B. Are the data presented in

  Table 2 consistent with this hypothesis?

In a scatter plot comparing the temperature of a solution to the rate of a chemical reaction, what does a cluster of points rising from left to right suggest?

• As temperature decreases, the reaction rate increases.

• Temperature has no effect on the reaction rate.

• As temperature increases, the reaction rate decreases.

• As temperature increases, the reaction rate increases.

When you create a graph the independent variable goes on the x axis.

• true

• false

Answer explanation

The statement is true because the independent variable, which is manipulated by the experimenter, is typically placed on the x-axis in a graph.
