Option C
Plants, cellular respiration accurately represents a carbon source and the process that releases carbon from that source
<u>Explanation:</u>
Every existing body supplies CO2 off while they evoke power from their food through cellular respiration. Plants and creatures present off CO2 while living and respiring and during lifeless and rotting. Plants are significant carbon sinks, gaining up enormous volumes of CO2 through the manner of photosynthesis.
While plants also discharge CO2 during the means of respiration, the volume of CO2 exercised up by plants by photosynthesis and discharged by exhalation approximately matches out. Volcanic action, forest wildfires, and diverse anthropological exercises deliver carbon.
Answer:
The glowing splint test is a test for an oxidizing gas, such as oxygen. In this test, a splint is lit, allowed to burn for a few seconds, then blown out by mouth or by shaking. Whilst the ember at the tip is still glowing hot, the splint is introduced to the gas sample that has been trapped in a vessel. Oxygen supports combustion so a good method of testing for oxygen is to take a glowing splint and place it in a sample of gas, if it re-ignites the gas is oxygen. This is a simple but effective test for oxygen.
