Question

juans science project
for her science project, juan planted four lima - bean plants under different lighting conditions. plant 1 was in a
very sunny area, and plant 2 in higher sunlight. plant 3 was placed in a dark corner, and plant 4 received constant light.
the plants were watered regularly. after 10 days, juan measured the height of the plants. after 10 more days,
it was shown that plant 4 reached 12 inches each day.

growth of lima bean vines
according to the graph, which plant grew at the most constant rate?
a. 4
b. 2
c. 3
d. 1

Explanation:

Step1: Identify the constant - rate concept

The plant with the most constant rate of growth will have a linear graph with a steady slope.

Step2: Analyze the graph

By observing the lines in the graph for each plant, we can see that plant 2 has a relatively straight - line graph compared to the others, indicating a more constant rate of growth.

Answer:

B. 2
