High concentrations of carbon monoxide co can cause coma and possible death. the time required for a person to reach a cohb level capable of causing a coma can be approximated by the quadratic model tequals .0002 squared minus.316 plus127.9, where t is the exposure time in hours necessary to reach this level and 500less than or equals xless than or equals 800 is the amount of carbon monoxide present in the air in parts per million (ppm). a) what is the exposure time when xequals 750 ?

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.
