Why do scientists use STP? options: A. STP has no negative numbers which makes calculations easier. B. Because temperature and pressure affect gases, scientists want to "standardize" the conditions at which gases are studied. C. Using 500 K and 500 kPa for standard temperature and pressure, conditions are kept constant. D. STP is used so that the Celsius temperature can be used in gas law calculations

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.
