## Step 1The problem asks us to identify the commonalities between two processes: burning food on a stove and cellular respiration. ## Step 2Burning food on a stove is a chemical change. This is because when food is burned, it undergoes a chemical reaction with oxygen, producing new substances such as carbon dioxide and water. This process is known as combustion, which is a type of chemical change.## Step 3Cellular respiration is also a chemical change. This process involves the breakdown of glucose and other molecules in the presence of oxygen to produce energy, carbon dioxide, and water. This process is also a chemical change because new substances are formed.## Step 4Therefore, the commonality between these two processes is that both are chemical changes.
