5. Many plants and trees, with the help of a nitrogen-fixing bacteria, take nitrogen from the air and
convert it into a usable form. A student wants to find out if the redbud tree helps to put nitrogen into
the soil. She designs an experiment in which she measures the amount of nitrogen in the soil around
redbud trees and pine trees, before and after nitrogen-fixing bacteria are added to the soil.
What is a logical hypothesis for the student's experiment?
a.
Redbud trees grow faster when soil nitrogen is present.
b. Nitrogen-fixing bacteria populations grow faster when soil nitrogen is present.
Redbud trees increase soil nitrogen levels with the help of nitrogen-fixing
bacteria.
C.
d. Nitrogen-fixing bacteria increase soil nitrogen levels.

4. Consider this hypothetical experiment then answer the following questions. An agricultural researcher is studying a specific species of apple tree and conducts the following experiment: Every week from April through September, she sprays 20 trees with a specific volume of a chemical pesticide, 20 trees with water (using the same volume as the pesticide spray), and 20 trees are not sprayed at all. At the end of September, she sends her graduate interns out to the orchard to harvest all the apples. The interns pick all the apples, weigh them, and record detailed quantitative and qualitative data in their lab notebooks. 
a. What might be a question that prompted the researcher's experiment?
b. Construct a possible hypothesis, based on the question and the experiment the researcher conducted.
c. What is the independent variable?
d. What is the dependent variable?
