DNA is an evolutionary clock that's extremely useful in our lives because it mutates. The mutations that occur in our DNA causes the organisms to diverge evolutionarily from one another, providing us our natural clock in the timeline of evolution.
You could describe it's shape, color, varieties on sizes and shape of states, how it's rounded but with a top and bottom.
The process is replication
Answer:
0.533 mol O2
Explanation:
4 Fe3O4 + O2 -> 6 Fe2O3
1 mol O2 -> 6 mol Fe2O3
x -> 3.2 mol Fe2O3
x = (3.2 mol Fe2O3 * 1 mol O2)/ 6 mol Fe2O3
x= 0.533 mol O2
