A student did an experiment with two identical plants, Plant 1 and Plant 2. About 10 mL fertilizer was added to Plant 1. About 200 mL of water was added to each plant every day. The height of the plants was recorded over a period of 5 weeks in the table shown below.
Week Height of Plant 1 (in inches) Height of Plant 2 (in inches)
1 12.6 12.6
2 13.8 12.9
3 14.9 13.4
4 15.7 13.8
5 16.6 14.6
Based on the table, which of these conclusions is correct?
Fertilizer helps plants grow taller.
Fertilizer can help a plant survive for five days.
Plants need more than 10 mL fertilizer to grow in size.
I choose A is it right?
a is the best choice.
correct
Based on the table, the correct conclusion would be:
A. Fertilizer helps plants grow taller.
This is evident by the fact that Plant 1, which received 10 mL of fertilizer, consistently grew taller compared to Plant 2, which did not receive any fertilizer. The heights of Plant 1 were consistently higher than Plant 2 throughout the 5-week period.
Based on the table given, the correct conclusion is indeed option A: "Fertilizer helps plants grow taller."
To determine this, you can compare the height of Plant 1 (which received 10 mL of fertilizer) with the height of Plant 2 (which did not receive any fertilizer). Over the course of 5 weeks, Plant 1 consistently grew taller than Plant 2. For example, in week 1, both plants had the same height, but in week 5, Plant 1 reached a height of 16.6 inches, while Plant 2 only reached a height of 14.6 inches.
This trend indicates that the addition of fertilizer to Plant 1 contributed to its increased height compared to Plant 2. Therefore, it can be concluded that fertilizer helps plants grow taller.
