C Correct answer
Explanation

Statement 1 is correct. When things are at their most basic breaking down state, they tend to last longer. Such is the same for a rubber band, when a rubber band is stretched it causes its polymer chains to become very ordered and it expels thermal energy (heat) thus extending its life. Statement 2 is also correct. The thickening power of cellulose also allows for more air to be whipped into products like ice cream, or whipped topping.
