List the substrate and the subunit product of amylase. _starch & maltose respectively__ 2. What effect did boiling and freezing have on enzyme activity? Why? How well did the results compare with your prediction?__Boiling caused amylase to be denatured‚ thus inactivating the enzyme. Freezing has no effect. The function of an enzyme is directly related

As of today I still feel like that one of the hardest positions to work in is corrections. In corrections you have jails‚ state prisons and federal prisons‚ but there are different security levels within them. I will be briefly discuss the history of corrections and also give your insight to an employee who works in a prison system here in Atlanta‚ Georgia and get some personal views in his field of work. First I would like to start off by talking about jail and it is used to house criminals for
