Question 1

Question

Kali designs a set-up to investigate germinating seeds. She fills a jar with seeds that have soaked in water.
In the jar, she places a beaker that contains a solution of bromothymol blue. Bromothymol blue turns green in the presence of carbon dioxide.
She will record observations on Day 1, wait 24 hours, and record again on Day 2.
Day 1
Day 2
Bromothymol
blue solution is blue
Soaked seeds
Bromothymol
blue solution is green
• Germinating seeds
Which question has Kali MOST LIKELY ASKED as she set up this investigation?
d
Do germinating peas absorb water in the process of photosynthesis?
Do germinating peas release oxygen in the process of respiration?
Do germinating peas release water in the process of photosynthesis?
Do germinating peas release carbon dioxide in the process of respiration?

Answer 1

The question that Kali has MOST LIKELY ASKED as she set up this investigation is:

Do germinating peas release carbon dioxide in the process of respiration?

This is indicated by the observation of the bromothymol blue solution changing from blue to green, which signifies the presence of carbon dioxide produced during the respiration of the germinating seeds.
