14 When a nitrogenous base is inserted into the DNA sequence of a gene, the protein product of the gene is usually nonfunctional.
Which of the following statements best explains why?
A The inserted base increases the rate of translation in the corresponding mRNA sequence.
B The inserted base causes the DNA sequence to be transcribed into the mRNA in the opposite direction.
C The inserted base sequence causes the codons in the mRNA sequence to be incorrect for the desired protein.
The inserted base signals enzymes to translate the DNA sequence rather than the RNA sequence into protein.

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 principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
