Some processes that occur in a cell are listed below. a. utilize energyb. detect changes in the environmentc. rearrange and synthesize chemical compoundswhich processes will all living organisms use to maintain homeostasis? (1) a and b, only (3) c and a, only(2) b and c, only (4) a, b, and c

idk what the question is about

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.
