Question

9 multiple choice 2 points lydia works in a flower shop after school. she notices that the hydrangeas in container 1 have pink blossoms, while the hydrangeas in container 2 have blue blossoms. she makes sure they all receive the same amount of light and water. her boss tells her that the flowers were all grown from the same seed variety. lydia discovers, after testing the soil, that although the same type of soil was used, the soil in container 1 has a ph of 6.0, and the soil in container 2 has a ph of 5.0.lydia most likely conducted her investigation to answer what question about hydrangeas? do varying degrees of light affect hydrangea color? what type of soil will produce a hydrangea with both pink and blue blossoms? what role do genetic factors play in hydrangea color? how does the chemistry of the soil affect the color of hydrangea blossoms?

Explanation:

• Lydia controlled light and water (kept them the same) and found a difference in soil pH (a chemical property of soil) while hydrangea colors were different.
• The first option is wrong as light was controlled (same for both containers).
• The second option is wrong as there's no indication in the problem about looking for a soil type with both pink and blue blossoms.
• The third option is wrong as it's stated that flowers were from the same seed variety (so genetic factors are the same, not being investigated here).
• The fourth option is correct as she is looking at how soil (specifically its pH - a chemical aspect) affects hydrangea blossom color.

Answer:

How does the chemistry of the soil affect the color of hydrangea blossoms?
