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.
Which question has Kali MOST LIKELY ASKED as she set up this investigation?
a
Do germinating peas release water in the process of photosynthesis?
b
Do germinating peas release carbon dioxide in the process of respiration?
c
Do germinating peas release oxygen in the process of respiration?
d
Do germinating peas absorb water in the process of photosynthesis?
b
Do germinating peas release carbon dioxide in the process of respiration?
b
Do germinating peas release carbon dioxide in the process of respiration?
The question that Kali most likely asked as she set up this investigation is:
b) Do germinating peas release carbon dioxide in the process of respiration?
Explanation: Kali is using bromothymol blue, which turns green in the presence of carbon dioxide, to investigate the release of carbon dioxide by germinating peas. By setting up this experiment, Kali aims to observe and record any change in color of the bromothymol blue solution, which would indicate the release of carbon dioxide through respiration.
