"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 carbon dioxide in the process of respiration? b Do germinating peas release oxygen in the process of respiration? c Do germinating peas release water in the process of photosynthesis? d Do germinating peas absorb water in the process of photosynthesis?"

Answer 1

The question that Kali has most likely asked as she set up her investigation is:

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

This is indicated by her use of bromothymol blue, which changes color in the presence of carbon dioxide. Her setup aims to observe changes over time, which would provide insight into whether the germinating seeds are producing carbon dioxide as a byproduct of respiration.
