An experiment is designed to determine if wheat grows better when it is planted alone or with clover. The design calls for 3 pan

s of each treatment. Pans A, B, and C contain only wheat. Pans D, E, and F contain clover and wheat planted in alternating rows. Each pan contains a total of 100 seeds. All treatments contain the same type of soil, are planted in the same size pan, are exposed to the same amount of sunlight, and are maintained at the same temperature throughout the course of the experiment. Use the passage in red to complete the following statement: The treatments planted with only wheat are the A. sample sizeB. The controlC. environmental variableD. null hypothesis

Answer: Option B

Explanation:

Usually in scientific experiments, at least one parameter is checked; here, the growth rate of wheat in two different conditions is being evaluated.

Hence, growth rate of wheat alone in pans A, B and C becomes the standard or referential control against which the experimental control (Wheat + clover) in pans D, E and F is evaluated, since both treatments are exposed to the same external conditions.
