i won't dgest the starch, since it's not on its optimal conditions....
37 degrees Celsius
Serratia marcescens incubated at 37 degrees Celsius will have almost a clear pigmentation. However, when S. marcescens is incubated at 25 degrees Celsius it will produce a very distinct red color.

water temperature
it would become a lot slower.. just sayin!
identify two pH values at which salivary amylase activity stop?
the rate would be slower because some enzymes are resistant to temperature change (denaturation)
Usually around 45 degrees Celsius. hope this helps!
Amylase works best at body temperature, which is around 37 degrees Celsius. This is because if the temperatre is too low, the amylase will collide slow as the kinetic energy will be low. It reacts fastest and best in this temperatue as lota of kinetic energy is given to the molecules and the particles therefore collide faster. Although, when the temperature is too high, the enzymes (amylase) gets denatured which means that they loose their shape. This way they do not react.
E. coli lives in the intestines and is adapted for living there. The average body temperature is 37 degrees Celsius
