A student poured a solution of bromothymol blue indicator into three test tubes. Then he placed an aquatic plant in two of the test tubes, as shown below. He placed a stopper on each test tube and placed them all in the dark for 24 hours. Bromothymol blue turns from blue to yellow in the presence of CO2
Predict what will happen to the test tubes in Figure 9–9 after 24 hours in the dark.
In the dark the aquatic plant won't do photosynthesis. Instead it will do cellular respiration in which it will produce CO2. Therefore after 24 hours of letting the plant in the dark introducing Bromothymol in the solution will cause it to turn yellow.

What is terrestrial species?An animal or plant that lives on land or in the ground, as opposed to the sea, trees, or the air, is said to be terrestrial. There are occasionally aquatic and terrestrial animals seen sleeping next to each other under a loose stone.
These animals can run quickly because the majority of them have legs. They must move quickly to capture their prey or avoid being an animal's next meal (predators). Komodo dragons and red-tailed boas have so many differences, even though they share a common ancestor.
Therefore, Order Urodela has amphibian with aquatic and terrestrial species with very flexible bodies, has a tail, and retains its juvenile features throughout its life.
