Step-by-step solution
A - 3: Joseph Priestley observed that in a closed bell jar, both the candle and mouse would suffocate or extinguish due to the depletion of oxygen, demonstrating that both combustion and respiration use up the air (oxygen). B - 1: When Priestley placed a mint plant in the same bell jar, he found that the air was "restored," allowing the candle to burn again and the mouse to survive, showing that plants release a substance (oxygen) that restores the air. C - 4: Ingenhousz's experiment with an aquatic plant showed th
