The decay of uranium isotopes is used to provide information about  the age of Earth. 
<h3>
Explanation:</h3>
Isotopes of Uranium U-232, U-233 , U-234 , U-235 , U-236 , U-238 are used as fuel in nuclear reactors or as explosives for nuclear weapons. Uranium 238 is not very radioactive and it constitutes for nearly 99.3% of natural uranium on Earth and has the longest lifetime: its period is 4.5 billion years, about the age of Earth. 
Use of radiometric dating techniques help in defining the age of substances (natural or man-made) using the known decay rates of radioactive elements. Each element has an  individual decay rate and half life time.
Two Uranium isotopes (U-238 and U-235) are used for radiometric dating. Both the isotopes have different decay rates and half life period. Both are unstable and radioactive. Since two different isotopes produce two different decay clocks (one as a reference to other), it is beneficial in accurately determining the age of samples. The age of earth (rocks or other natural elements) can be easily determined using Uranium isotopes.
 
        
             
        
        
        
Answer:
Hello your question is incomplete attached below is the complete question
answer : = 1.25
Explanation:
i) Determine the rate of mtDNA percent divergence 
From the data given the most closely related specie is Chimpanzee ( 8.8 sequence  difference ) 
Note : Given that this divergence took place seven million years from now 
∴The rate of mtDNA percent  divergence per 1 millions years 
 = 8.8 / 7 = 1.25
