Certain bacteria change nitrogen gas into a usable form in a process called ______________________________. 42. A student wants to determine if added nitrogen will help plants grow taller. The student sets up two groups of plants. Group 1 consists of plants with added nitrogen and Group 2 consists of the plants without nitrogen. The student makes sure to use the same type of plant. He measures the plant growth weekly. A. What is the dependent variable?____________________________________________________________ B.
