Answer:
The bones are homologous structures
Explanation:
Homologous structures are the structure which are found similar in appearance in different organisms.
The homologous structures in different organism shows that they shared a common ancestor or they diverged from a common ancestor during course of evolution that is these homologous structures are the result of the divergent evolution.
In the given question, the bat, dolphin and the cat shows the same structure of bone which indicates that they have evolved from a common ancestor and is true as they all belong to mammals.
Thus, the bones are homologous structures is correct.
The answer is 1836 nucleotide bases.
<span>It is known that three nucleotide bases in mRNA are called codon and that each codon codes for the specific amino acid. For 3 nucleotide bases in mRNA, there is 1 amino acid in a protein. So, there are 3 times more nucleotide bases in mRNA than amino acids in the protein. This can be represented mathematically:
3 nucleotide bases : 1 amino acid = x nucleotide bases : 612 amino acids
3 nucleotide bases x 612 amino acids : 1 amino acids = x </span><span>nucleotide bases
x nucleotide bases = 612 x 3 nucleotide bases
x nucleotide bases = 1836 nucleotide bases.
So, mRNA long 1836 nucleotide bases will give a protein with 612 amino acids.</span>
Is the question multiple choice?
I think so because tigers are very intellectual creatures in which could learn to adapt to new environments.
