Explanation:
Could intelligence simply be unlikely to evolve? Unfortunately, we can’t study extraterrestrial life to answer this question. But we can study some 4.5 billion years of Earth’s history, looking at where evolution repeats itself, or doesn’t.
A DNA temp is used to make a RNA strand !!
so your answer is C !!

Answer:</h2>
The force is <u>plate tectonics</u>.
<h2>
Explanation:</h2>
The lithosphere, which is the inflexible peripheral shell of a planet, is broken into structural plates. The Earth's lithosphere is made out of seven or eight significant plates (contingent upon how they are characterized) and numerous minor plates. Where the plates meet, their relative movement decides the sort of limit: focalized, unique, or change.
Seismic tremors, volcanic action, mountain-building, and maritime channel development happen along these plate limits. The general development of the plates normally runs from zero to 100 mm yearly.
<span>Sunset, this is really similar to the question about molecular clocks you asked. The more closely related the three species are, the more similar the homologous proteins will be in each of the species.
Defining 'sequence similarity' is a little bit nuanced. It can refer either to the genetic code or the amino acid code. Because the genetic code is degenerate multiple codons code for the same amino acid - mutations in the gene don't result in mutations in the proteins when the mutated codon codes for the same amino acid as the unmutated codon.
Similarly, you can sort of think of some amino acids as being redundant. In some cases, replacement of one amino acid with another doesn't result in all that much change to the protein's structure or function. The result is, as species diverge and mutations build up, they build up preferentially in certain domains of the protein and more frequently involve replacement of one amino acid with one which is pretty much similar to it.</span>
