The graph illustrates the relative activity levels of three common digestive enzymes, where 0 represents no activity and 12 represents the highest level of activity. which enzyme is least active at a neutral ph of 7?

question 2 options:

trypsin

amylase

pepsin and amaylase

pepsin

C) amylase

Explanation:

Amylase, found in saliva, is most active at a neutral pH of 7. This pH is too high for pepsin and too low for optimum trypsin activity.

the answer is tropical areas. the tropical areas obtain more

radiant energy from the sun than they lose to space through terrestrial

radiation, and vice versa for polar areas. earth has an energy remaining in the

tropics and an energy scarcity for the polar areas.

explanation:

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
