The question is incomplete. The complete question is - A student poured a solution of bromthymol blue indicator into three test tubes. Then, he placed and 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. Brothymol blue turns from blue to yellow in the presence of CO2.

Which process would you expect the organisms in the test tubes to carry out-- cell respiration, photosynthesis or both? When would you expect each process to occur?

Answer:

Photosynthesis is the process of the formation of the food in case of plants in the presence of sunlight with the help of carbon dioxide, water and soil. The light energy is converted into the chemical energy.

The beaker is blue because plants uses carbon dioxide for their food preparation. When the beakers are kept in the dark place, instead of photosynthesis cellular respiration occur that made energy from the food for their survival.

Why is fishing for some kinds of ocean fish controlled by laws?
lora16 [44]
C is the answer. Due to the current state of the world economy; people, if left to their own devices, would fish as much as possible so they can sell their fish to make money. Current technology means we can catch as many fish as we want (trawlers etc.). The problem with this is that there is only a finite amount of fish in the sea. If we were to fish them without limits in place, we could cause them to go extinct.
