Salivary amylase

pepsin .hope it helps...

Digestion is the breakdown of carbohydrates, proteins and fats into small soluble substances to be absorbed into the blood. Amylase, proteases and lipases are enzymes that are important in digestion.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
