These statements are both true. However, tuna are warm blooded and all other fish (but mackerel shark) are cold blooded. There are many fish that swim in both the Atlantic and Mediterranean. Therefore the answer must be B.
Answer:
Explanation:
As water temperature increases, the amount of O2 dissolved in water decreases.
The graph looks something like this (though not exactly. It just has the same sort of shape.)
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 /><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 /><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.
