Answer:
The correct answer is - B. Water plants in the solution are placed under a bright lamp.
Explanation:
As we know adding carbon dioxide in as solution result in the change of its acidity this is the result in the indicator to change from blue to yellow. In the question, it is asked that what factors from the given option will cause yellow indictor to blue which means what factors cause the solution to be alkaline from acidic.
Placing the green water plants in the solution under a bright lamp will cause the is utilizing and remove present carbon dioxide in the solution and leads the to blue color from the yellow color of the solution.
Carbon cycle :
- CO2 is given out when organism breathe
- Plants gather this CO2 to produce oxygen
- Oxygen that is produced by the plants is used for other organism's breathing which will given out another CO2 and repeat the cycle
Water Cycle :
- Water from the sea and lake is evaporated and Turned into Clouds
- When atmosphere cool it down, these clouds will condense and turn into rain
- Eventually this rain will flow back to the lake or sea and it will repeat the cycle
