Final answer:
As a banana ripens, physical changes cause the peel to change color from green to yellow to brown.
Step-by-step explanation:
True. As a banana ripens, physical changes cause the peel to change color from green to yellow to brown. This is due to the breakdown of chlorophyll, the pigment responsible for the green color, and the production of other pigments such as carotenoids, which give the banana its yellow color, and anthocyanins, which give the banana its brown color.
