The answer to this question is most likely A) Protein coat.

To know this, we must know that a virus is a single-celled organism AND classified as prokaryotic (meaning it has no nucleus like Eukaryotic cells do).

A nuclear membrane is a covering that we have around every single eukaryotic cell in our body (also known as a cell membrane), NOT prokaryotic cells.

A tail (or flagellum) is located on the side of some cells in our body and most bacterial cells.

An endospore is a resistant, asexual spore that develops in a bacterial cell.

The only choice that would make even the slightest sense is A) protein coat.

Answer from: Quest

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.
