produce which of the following? - ....🔰VERIFIED ANSWERS.... ✔✔Water
A student uses stationary fans to investigate the effect of wind on water loss by
plants. The student divides the plants into three treatment groups and places
each group in front of a fan. The student sets the fan for each group to one of
three different levels: low, medium, or high. After 24 hours, the student
determines the amount of water that was lost by each plant. To create a bar
graph of the results, the student should make the height of each bar represent

loss for each treatment group
