Question

question 8
kali designs a set - up to investigate germinating pea 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?
o a do germinating peas release oxygen in the process of respiration?
o b do germinating peas release water in the process of photosynthesis?
o c do germinating peas absorb water in the process of photosynthesis?
o d do germinating peas release carbon dioxide in the process of respiration?

Explanation:

Kali uses bromothymol blue which turns green in the presence of carbon - dioxide. The color change from blue to green in the solution indicates the presence of carbon dioxide. Since the experiment is about germinating pea seeds and the color change of bromothymol blue, she is likely investigating if germinating peas release carbon dioxide during respiration.

Answer:

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