Solution

Q7: (D)

Sharp bell shaped curve represents enzyme activity of thermophiles. Activity increases steeply and peaks at around its optimal temperature before denaturation (sharp loss in activity)

Q8. 70C

activity of an enzyme is highest at optimal temperature, for this thermophile it is around 80C
