Answer:
A. Independent variable 2. dominant tree species
B. Dependent variable 3. tree survival rate after the fire
C. Controlled variable 1. thinning or no thinning before the fire elevation of the site
Explanation:
A. An independent variable doesn't undergo changes during the experiment because it is not conditioned by other variables in the experiment. In this example, dominant tree species represent a variable that is independent of the experiment itself.
B. A dependent variable is those that you need to measure and depends on the other factors in the experiment. In this example, tree survival is dependent on the factors that affect the results (i.e. humidity in the trees, presence of resinous material in the trees that are non-combustible, etc.)
C. A controlled variable is those that we use to observe an expected outcome in the experiment and therefore it is used to compare with the test group. In this case, thinning or no thinning are used as positive and negative controls, respectively, because they enable their comparison with the test group in the experiment.

It occupies an area of 174,000 square miles, spreading across 8 Great Plains States.
Answer:
Diploid cells abbreviated 2n and haploid cells abbreviated 1n because 'n' represents number of chromosome present in the cell. In haploid cells the number of chromosome is half in number while in diploid cells the number of chromosome is double so that's why haploid is abbreviated as 1n and diploid is abbreviated as 2n.
Diploid cells are present in body cells while haploid cells are found in sex cells.
