Question

wild type bret 2. To test whether the environment influences the mumber of branches formed, the scientists planted wild type plants and bre! mutant plants at vari- ous planting densities, and measured the degree of branching in these plants. Their data is presented in Figure 2. What are the rwo major conclusions in this experiment? In your statement, please clearly identify (1) the independent variable, (2) the dependent variable, (3) the type of evidence presented in this experiment, and (4) how the dependent variable is d/// Figure 2 The number of branches was measured in the bre/ loss of-function mutant and the wild-type plants grown at different planting densities Density 1.4,9, and 16 indicate 1,4.9, and 16 planss per pot, respectively.

Explanation / Answer

Independent variable = crowding (number of plants per pot)

Branching in isolated plants is higher compared to the crowded plants. This concludes that:
