While testing amylase activity, john uses a buffer of ph 6 and substrate starch. he incubates then at 104f (40c).all the tubes show glucose formation, except one, which had no starch solution. why did this happen

is this a psat question, if so do not cheat try your best.

rising temperatures because when water vapor in the air is cooled, it condenses. it turns back into a liquid and attaches to dust particles in the air. these very small water droplets group together to form clouds

where in your body is there an enzyme that does function at a high or low ph? what is the name of that enzyme and its function?

it is a. i hope this .
