In this lab, a hydrometer is used to measure the density of sugar solutions. What would happen if the same hydrometer was used to measure the density of alcohol solutions? Density of water 1.00 g/mL Density of alcohol 0.79 g/mL The hydrometer will sink lower as you increase the amount of alcohol in the solution, because the alcohol will increase the density of the solution. The hydrometer cannot be used to measure the density of alcohol solution: it can be...

You are studying a bacterium that utilizes a sugar called athelose. This sugar can be used as an energy source when necessary. Metabolism of athelose is controlled by the ath operon. The genes of the ath operon code for the enzymes necessary to use athelose as an energy source. You have found the following: The genes of the ath operon are expressed only when the concentration of athelose in the bacterium is high When glucose is absent, the bacterium needs...

When you ran the ALP assay using pNpp, you could use a high concentration of pNpp. If you run the ALP assay using pNp and ATP, you must use a lower concentration of pNp. Why?
