While performing an experiment on the enzyme amylase, macy uses three different ph solutions: ph 3.0, ph 4.0, and ph 6.7. she finds that all the starch is broken down fastest at ph 6.7. how would you justify these findings?
a. the optimum ph for amylase is ph6.7, at which the rate of reaction is the highest.
b. the minimum ph for the amylase is ph6.7, after which the reaction takes minimum time for completion.
c. the optimum ph of amylase is between ph3.0 and ph 4.0, at which the enzyme takes maximum time for completion

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
