<span>The following are the energy systems that the body would use to provide a person with energy throughout a race:
>ATP-PC-high power, short duration,
ATP-PC system can make energy at about 36 calories minute.
>Glycolytic-moderate power/short duration
can produce energy at about 16 calories per minute.
> Oxidative-low power/long duration.
creates 10 calories per minute, approximately.</span>
Females are A. XX. Males are XY :)
<span>In marine vertebrates, the gill arches use the external gas exchange. The water holds less oxygen.
The ribs in terrestrial vertebrates have enclosed respiratory surface which is inside the body and comes as paired lungs.
Kidneys are efficient in excretion of regulation of water and nitrogenous wastes. Their reproduction is normally sexual with separate sexes.</span>

Answer:
The two problems that the transfer of information from DNA to protein must overcome are:
- How to bring the information from the nuclear DNA to the place of protein synthesis?
- How to convert this DNA information into amino acids and then into proteins?
Explanation:
The genetic information is found in the DNA and depends on a specific sequence of nitrogenous bases. This information is transcribed into the messenger RNA, whose base sequence is organized into triplets and codons, each of which encodes an amino acid, as well as establishing the pattern for starting and stopping the synthesis of a protein.
<h3>How to bring the information from the nuclear DNA to the place of protein synthesis?
</h3>
The DNA must be transcribed into messenger RNA (mRNA), a process that occurs in the nucleus of the cell. mRNA leaves the nucleus and travels to the cytoplasm, where amino acid synthesis will take place.
<h3>How to convert this DNA information into amino acids and then into proteins?</h3>
Once in the cytoplasm mRNA binds to ribosomes, structures in charge of translating the sequence of nitrogenous bases RNA to synthesize amino acids. The set of ribosomes and rough endoplasmic reticulum are in charge of the assembly of amino acids to produce peptides and proteins.
