According to cell theory, scientists do not classify a virus as living because it does not have a) a membrane. b) genetic material. c) cellular structure. d) any organic molecules.

Answer;

- Cellular structure

According to cell theory, scientists do not classify a virus as living because it does not have cellular structure. Viruses have a simple cellular structure.

Explanation;

-Cell theory states that all living things are composed of one or more cells; a cell is the smallest unit that still retains the properties of life; and new cells only come from cells that already exist.

Viruses have a simple cellular structure. The new definition makes no reference to cells or organelles. Instead it uses the term "unit". A molecule could be a unit. A crystal could be a unit. A cell could be a unit.

maritime tropical may be your answer.

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.
