A) Ingenhous

Answer 2

B) Priestly

Explanation:

• Joseph Priestly conducted an experiment to prove that oxygen is released by plants.
• The candle flame used up the oxygen and went out and the mice died due to lack of oxygen.
• When he kept the plant inside the jar there was a continuous supply of oxygen and the mice survived.
• During photosynthesis, plants use carbon dioxide, water, and sunlight to make food and they give off oxygen as a result.
• Thus without oxygen life in this planet would not exist.
