it turns black because air is around it when u open a banana use airtight Ziploc i read this in a science from scientist
When iodine comes into contact with starch, it turns black. A normal piece of paper has additive starch to make it stiffer, so when the paper comes into contact with iodine, it will turn black.
When iodine is added to starch it turns a blackish color due to a chemical reaction.
Dark blue very, near to black
the eggs are laid in the banana and when they hatch, the larva feed on the banana
A ripe banana had more time to go through mitosis rather than an unripe banana had a lower time
it stanks
Chemical change
Because they rot quicker. There's a greater surface area , both the inside and the outside , that is exposed to the air .
potassium in the banana reacts to water and melts the banana
If neither has been peeled/bitten, the banana. If they've been peeled/bitten, the apple.
BlackAns2:It is very unlikely that a ripe banana will have enough starch to turn iodine black. When iodine turns black, it is a positive test for the presence of starch.
yes, if it turns into a different colour than it is a chemical reaction. hope that helps
Well just place your left hand shove it down the toilet and grab for the banana then if its not peeled eat it
To start, make a small cut near one of the tips, then peel off a strip of the skin, then peel off more strips until it is all peeled (generally a banana can be peeled with 4 or 5 strips).
Yes
It is rotten and mushy and should not be eaten like a ripe banana. However, it is good for making banana bread.
This Banana turns blue!
