Explanation:
No, A robot is a non-living thing. It is because although a robot has the ability to do work, walk or run and even recent researches even made a robot to think on their own. But they do not have feelings. If ROBOT was a living thing then its works would be automatic and it would not require human help.
<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>
