A student was talking with her younger brother about what she was learning. She asked him if he knew how food and oxygen got to the cells in the body. He responded, Sure, I know. This is how it works: We eat food, and it goes through food tubes to the cells. We breathe in air, and it goes through air tubes to the cells in the body.
Build on the younger brother’s ideas to provide a more scientific description of what happens when food and oxygen enter the body and travel to cells.

What relationship exists between an enzyme and a catalyst?

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution
