Explain how the nucleolus, ribosomes, endoplasmic
reticulum, golgi apparats function together in protein
synthesis.

The nucleolus refers to a condensed region of chromatin where the production of ribosomes takes place. Ribosomes are the regions of protein synthesis, which perform this function by aligning the amino acids in a suitable sequence, as directed by the messenger RNA.  

The ribosomes are generally found entrenched in the endoplasmic reticulum. The production of a huge amount of proteins is possible due to the presence of very large surface area provided by the ER to the ribosomes. The prime function of the ER is to transport the newly formed proteins over to the Golgi apparatus.  

The main function of the Golgi apparatus is to amend the proteins and administer them into the vesicles. From here they are mediated towards different cell parts. Hence, the mentioned cell organelles are associated with their activities of synthesis of proteins and transportation.  

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.
