Leigh is preparing popcorn for her friends. She removes a stick of butter from the refrigerator and cuts a fourth of it from the rest. Leigh remembers her lesson in school today about the conservation of mass that occurs during state changes. She wants to test what she learned, so she measures the mass of the butter she will melt. Its mass is 35 g. Then, she places the butter in the microwave and melts it. What should the mass of the liquid butter be once it is melted?

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
