Read the following passage. Before Rutherford conducted the gold foil experiment, the "plum pudding" model proposed by J. J. Thomson offered an explanation for the structure of the atom. Rutherford, along with two of his associates Hans Geiger and Ernest Marsden, performed an experiment in which an extremely thin metal foil was fired with a beam of alpha particles. The results of the experiment were recorded accurately by another scientist who observed the frequency of alpha particles that passed through the foil unobstructed. Use information from the passage to justify whether the characteristics of reliable scientific explanations are present in the development of the atomic theory.

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.
