Reforestation is the natural or intentional restocking of existing forests and woodlands
Answer:
A. Green after being placed in the light because the plant would remove CO2 by photosynthesis; yellow after being placed in the dark because the plant would release CO2 by respiration.
Explanation:
According to this question, Bromothymol blue (BTB) is a chemical that can be used as an indicator of the pH of a solution. The presence or absence of CO2 in a solution decreases or increases the pH of the solution respectively.
- BTB appears green in a neutral pH i.e. little CO2
- BTB turns yellow in a low pH i.e. high CO2
Plants, in the presence of light, will perform photosynthesis and use CO3 as a reactant while in the dark, will perform cellular respiration and release CO2 as a waste product. Hence, in this case where an aquatic plant was placed into a test tube and covered it to keep it air tight.
- When placed under light for 24 hours, the aquatic plant will undergo photosynthesis and remove CO2 from the solution to make the solution appear GREEN due to neutral pH.
- When placed in the dark for 24 hours, the aquatic plant will undergo cellular respiration and release CO2 into the solution making the solution appear YELLOW due to low pH.

Rainforest would because of all the biodiversity, fungus and bacteria
Answer:
In a flashlight, energy must move from the power source (generally a battery) to the light source (frequently an incandescent bulb, sometimes an LED). However, every time energy changes form, some of it is lost as heat—a fundamental principle of thermodynamics
