Question 2
Experiment II. Base your answers to questions 36 through 39 on the information and graph below.
You perform an experiment growing three types of plants in equal amounts of soil. Three different types of plants are used. Each plant is 10 centimeters tall at the beginning of the experiment. The three plants are given 4 milliliters of water every day for 20 days. The results of the experiment are shown on the graph.
Graph: “Changes in Plant Height Over a 20-day Period.” Horizontal axis: Days. Plant 1 is solid, Plant 2 dotted, and Plant 3 dashed, as in the original legend.
36. Which plant was the tallest at the end of the 20-day period? (2 points)
37. Other than at the beginning of the experiment, on what day were plant 2 and plant 3 the same height? (2 points)
38. Which plant grew at the slowest rate from day 0 to day 5? (3 points)
39. During which time interval did plant 1 become taller than plant 3? (3 points)
A. Day 0–5
B. Day 6–10
C. Day 10–15
D. Day 15–20
