6 0

Answer: The number of codons in the sequence is 21.

Explanation: A codon is a triplet of nucleotide which codes for a specific amino acid. Each amino acid has at least one codon that codes for it. Three nucleotide residues is required to form a codon and to code an amino acid. Since there are 63 nucleotides in the sequence, the number of codons present in the sequence is 63 divided by 3. 63/3 = 21

Are birds more closely related to mammals or to reptiles
Zepler [3.9K]
Mammals. I am no scientist, but I think that they are closer to mammals due to the fact that they are warm-blooded, and they raise their young. Reptiles are cold blooded and usually leave their offspring to fend for themselves.

Animals of the same general body types have the same anatomy true or false​
horsena [70]

Animals of the same general body types having the same anatomy is True.

Anatomy is the study of the body parts, structures and functions of

organisms.

In situations where animals have the same general body type , then it means

they also have the same anatomy. A good example is mammals which have

the same structure of  body parts and the same anatomy.

Organisms with different body structures however have an entirely different

anatomy which is why True is the most appropriate choice.
