The answer is B. They bring oxygen from the air into the body.
The lungs don’t produce or release oxygen so it’s not A. or D. The lungs do not transform oxygen into carbon dioxide cause our bodies need oxygen not carbon dioxide so it’s not C. Hope this helps!
The only living thing that makes its own food is the plant. So the first step in a food chain is always a plant that makes its own food by sun. :)))
I hope this is helpful
have a nice day
DNA is the molecule that contains the genetic information that is transmitted hereditary and controls the cellular functioning
The original codons code for Leucine and Glutamic acid. The mutated codons code for Valine and Glutamine.
<h3>Genetic codes and amino acids</h3>
Each of the genetic codes. otherwise known as codons, translates to an amino acid.
Following the table of genetic codes with their respective amino acids:
- CTC (CUC) codes for Leucine
- GAG codes for Glutamic acid
- GTC (GUC)codes for Valine
- CAG codes for Glutamine
Thus, the glutamic acid in the original codon has been replaced with glutamine in the mutated codon while Leucine has been replaced with Valine.
