Q. Katie wants to see if apples that are kept cold will rot or stay edible. She places an apple in the refrigerator and records the date. What should she use as a control? (a) Keep an apple in the freezer (b) Keep an apple in boiling water (c) Keep an apple in a cool place (d) Keep an apple in a warm place

Answer keep an apple in the freezer

Explanation: low the temperature will be the less will be the chances for the apple to rot.This is because low temperature prevents the growth And reproduction of microorganisms. Freezer also helps by slowing down the food's own natural processes that lead to ripening and eventual decay.
