A radioactive isotope has a half-life of 2 minutes. How many total minutes will it take for 100-g of the isotope to get to just 6.25-g remaining

It would take 12 minutes.

8 minutes

Explanation:

G(g)                 T(min)

100 0

502

25 4

12.5    6

6.25 8

     another    way:

100/6.25 = 16

  16 = 2⁴       ( 4 half lives)    

Each half life is 2 minutes

so 4 half lives will be 8 minutes

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
