The correct option is 
Explanation:
From the question we are told that
the cell voltage for AD is 
From the data give we can see that

i.e 
In the same way we can say that

=> 

Found the choices. Pls see attachment.
The statements that explains this phenomenon are:
1) DNA contains adenine as one of its nitrogenous bases.
2) DNA has a double-stranded structure that ensures an accurate mechanism of duplication.
Answer:
From highest to lowest:
butanol: 117.7 degree Celsius
butanone: 79.64 degree Celsius
diethyl ether: 34.6 degree Celsius
n-butane: -0.4 degree Celsius
Although the process varies slightly from one material to another, the general process is as follows:
1) Choose an appropriate container for the solid. This may be a petri dish or a beaker in which you want to prepare the solution of the solid or any other lab equipment.
2) Place the container on a mass balance, then turn the balance on. The mass balance will automatically zero-out the mass of the container, so that any mass that you add on the container will be the mass of the solid. Alternatively, you may first measure the mass of the empty container alone.
3) Add the solid using a lab spatula. The solid should be added more slowly when the reading on the scale comes close to the desired value.
4) Remove the container from the mass balance after the desired amount of solid has been added.
The answer:
<span>the overall balanced equation for the precipitation reaction occurring between silver nitrate and calcium bromide:
