DNA . is a long, single chain of nucleotides
cannot determine behavior traits
contains coded information for the creation of proteins
is enclosed by a nuclear membrane in prokaryotes

The correct answer would be "contains coded information for the creation of proteins".

DNA or deoxyribonucleic acid is a polymer of nucleotides.

It is the genetic material in most of the living cells present on earth. That is, it controls all the characters and traits of the living organisms.

In prokaryotes, it keeps floating in the cytoplasm whereas it is confined in the well-defined nucleus in eukaryotic cells.

The nucleotide sequence of the DNA is used as the code for the synthesis of the proteins.

It is first transcribed into the nucleotide sequence of mRNA which is further decoded into the amino acid sequence of the proteins.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.

the answer would be d : p
