Make sure that you consume the banana when it is yellowing, and less green. This is because the quality carbohydrate structure and potassium level is at its highest potential.
ethylene
well it depend are you talking about just a banana or a cake or its both.... well if your talking about a banana. the banana is physcial change +++ Fruit ripening is chemical.
Digesting a banana is a chemical reaction, an ireversible change.
Dissecting a banana is a physical change, not a chemical reaction. It involves physically separating the banana into smaller pieces, but the chemical composition of the banana doesn't change. A reversible change would be when you freeze the banana slices and then thaw them, as this can be reversed.
A banana will slowly turn black as it starts to go rotten.
No it is not a reversible change.
Purely physical.
It's chemical change
Ethylene causes the ripening process, which also causes the color change.
It would not be a physical change. A physical change is when anything changes in state of matter. (solid, liquid, and gas). Unless your banana liquified it is not a physical change. Hope that helps! ;)
