Answer to Question 1

Possible color change is due to the breakdown of the hemicellulose, which is promoted by an alkali.

Answer to Question 2

Microwave cooking does not change the color of the vegetable as much as cooking on the stovetop. One reason is that they do not have to be in the microwave as long to be cooked so a reaction does not occur.
