Question

Which of these is an example of oxidation?

1.a baked potato
2.a peeled orange
3.an apple turning brown
4.an asparagus rotting

Answer 1

I believe It's 3. If it isn't it's probably 4, because that also has to do with change. (If I'm being honest none of these really pertain to oxidation, since it has to do with weathering things but eh.)

Hope I could help!

Answer 2

3. An Apple Turning Brown

Step-by-step explanation:

When an apple is cut (or bruised), oxygen is introduced into the injured plant tissue. When oxygen is present in cells, polyphenol oxidase (PPO) enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products.
