The process in which the environment<span> selects </span>organisms<span> that will survive is called natural selection. It starts with overproduction; when an </span>organism<span> produces more offpsrings than can survive. The second is variation. Because there are so many offsprings, there will be variations.</span>
In DNA, thymine binds to adenine, and cytosine binds to guanine. This means that there is an equal amount of thymine and adenine, and there is an equal amount of cytosine and guanine.
If there is 15% thymine, there should be 15% adenine.
Note that in real life, the percentage of bases won't be 100% equal.
The raw material from which sedimentary rocks are formed is D. Weathered remains of other rocks.
