Explicação

## Step 1<br />The problem presents two changes: a slice of banana turning brown and snails growing shells. We are asked to identify the commonality between these two changes.<br /><br />## Step 2<br />The first change, a slice of banana turning brown, is a result of a chemical change. This is because the browning of a banana is due to the oxidation of certain compounds in the banana, which is a chemical reaction.<br /><br />## Step 3<br />The second change, snails growing shells, is also a result of a chemical change. This is because the formation of a snail's shell is due to the deposition of calcium carbonate, which is a chemical compound.<br /><br />## Step 4<br />Therefore, the commonality between these two changes is that both are chemical changes.
