Question

question 1 - 7
scientists are studying the effects of different water modifications on plant growth (heated water, tap water, ice water, filtered water). plant growth was measured weekly and recorded. what conclusion can you draw from the data collected?
plant growth in inches each week
plant week 1 week 2 week 3 week 4 total plant growth
watered with heated water 0.5 0.8 0.6 0.8 2.7
watered with regular tap water 0.8 0.6 1.0 0.8 3.2
watered with ice water 0.4 0.4 0.4 0.4 1.6
watered with filtered water 0.5 0.8 1.0 0.8 3.1
ice water stimulated the most growth in plants.
plant growth varies based on water modifications.
growth of the plant was not impacted by the solution it was watered with.
plants watered with filtered water do not receive the proper nutrients needed to grow.

Explanation:

Step1: Analyze total growth values

We have total growths: heated water - 2.7 inches, tap water - 3.2 inches, ice water - 1.6 inches, filtered water - 3.1 inches.

Step2: Evaluate each option

• Option 1: Ice - water has the lowest total growth (1.6 inches), so it didn't stimulate the most growth.
• Option 2: The different total growth values (2.7, 3.2, 1.6, 3.1) show that plant growth varies based on water modifications.
• Option 3: Since growth values differ, growth was impacted by water type.
• Option 4: Filtered - water plants have a relatively high total growth (3.1 inches), so they likely received proper nutrients.

Answer:

Plant growth varies based on water modifications.
