Solve this: 3. Tali's sister cut an apple into small pieces and put them in water to stop them from browning. What will be the result of this with regard to the nutrients in the apple?

The answer to your question is as follows:-
Many fruits have iron in them which when comes in contact with Oxygen it rusts and gives brown colour, this process is supported by an enzyme called polyphenol oxidase. To prevent apple from rotting we simply soak it in a bowl of water so that it doesn't come in contact with Oxygen.
I hope the above answer helps you!
Cheers!
